ON THE HISTORY OF<br />

THE SWEDISH SECTION FOR DETONICS AND COMBUSTION<br />

(AFFILIATED WITH THE COMBUSTION INSTITUTE IN 1955)<br />

by<br />

Stig R. Johansson<br />

The Setting<br />

Alfred Nobel 1833 – 1896.<br />

It may not be a coincidence that <strong>the</strong> inventor of dynamite was a Swede ; Alfred Nobel. In Sweden, <strong>the</strong><br />

road towards industrialization was highly dependent on rock blasting, not only <strong>for</strong> <strong>the</strong> building of roads in<br />

a physical sense, but also, e.g., <strong>for</strong> use in <strong>the</strong> mine industry. An important mile stone on <strong>the</strong> road – in a<br />

metaphorical sense – is <strong>the</strong> building of railroads, <strong>and</strong> especially <strong>the</strong> railroad from <strong>the</strong> iron mine in Kiruna<br />

over <strong>the</strong> rocky mountain ridge to <strong>the</strong> ice-free Atlantic shipping port at Narvik in Norway. This gigantic<br />

undertaking around <strong>the</strong> turn of <strong>the</strong> previous century was facilitated by <strong>the</strong> fact that Sweden <strong>and</strong> Norway,<br />

until 1905, constituted a union under Swedish supremacy. Projects like this boosted <strong>the</strong> Swedish<br />

explosives industry, <strong>and</strong> engaged many skilful engineers, chemists, <strong>and</strong> physicists in <strong>the</strong> area of what is<br />

referred to today as "energetic materials".

The Founder<br />

Professor Carl Hugo Johansson (1898-1982) at <strong>the</strong> time when his 1949 “working group” became a<br />

Special Section of <strong>the</strong> National Committee <strong>for</strong> Mechanics within <strong>the</strong> Swedish Royal Academy of Sciences,<br />

KVA. (Courtesy <strong>the</strong> Royal Academy of Engineering Science, IVA.)<br />

A skilful physicist of a later generation was Carl Hugo Johansson. After a master’s degree in 1917 –<br />

at <strong>the</strong> age of 19! – in electrical engineering at Chalmers University of Technology, CTH, in Go<strong>the</strong>nburg<br />

<strong>and</strong> fur<strong>the</strong>r studies at <strong>the</strong> University of Lund, he became demonstrator to Professor Gudmund Borelius in<br />

1923 at <strong>the</strong> Department of Physics at <strong>the</strong> Royal Institute of Technology, KTH, in Stockholm. In 1939, he<br />

was appointed assistant professor at that department, where, up to 1945, he was instrumental in developing<br />

it into <strong>the</strong> prestigious Department of Technical Physics. Among his research achievements were <strong>the</strong><br />

discovery of <strong>the</strong> order-disorder rearrangement in metal alloys in <strong>the</strong> 1920s, <strong>and</strong> <strong>the</strong> periodic structure of<br />

alloys in <strong>the</strong> 1930s. His research in <strong>the</strong> field of <strong>the</strong>rmoelectricity led to <strong>the</strong> foundation of <strong>the</strong> absolute<br />

<strong>the</strong>rmoelectric scale.<br />

During World War II, Carl Hugo Johansson was one of <strong>the</strong> first scientists employed by <strong>the</strong> Swedish<br />

Military Physical Research Institute, which later became FOA, where he became deputy research director<br />

in <strong>the</strong> field of explosives in 1945. The following year he was appointed manager of <strong>the</strong> recently-started<br />

<strong>detonics</strong> laboratory of <strong>the</strong> Nitroglycerine Company at Vinterviken outside Stockholm. In 1957, he was<br />

bestowed a personal professorship. The rest of his life was devoted to explosives <strong>and</strong> rock blasting<br />

techniques. Detonics is, by <strong>the</strong> way, a word coined by him.

The Background<br />

Rock blasting<br />

A paramount civilian use of explosives in Sweden is <strong>for</strong> rock blasting, not least in mines. Mechanical<br />

<strong>and</strong> physical problems related to this use left <strong>the</strong>ir mark on <strong>the</strong> research activities in <strong>the</strong> field of explosives,<br />

activities dominated by <strong>the</strong> Swedish Detonics Research Foundation , SveDeFo. From 1953 to<br />

1963, Professor Johansson was managing director of SveDeFo, an organization which was also located at<br />

Vinterviken.<br />

Professor Johansson was a member of <strong>the</strong> Royal Academy of Engineering Science , IVA. He was<br />

engaged in IVA’s Section <strong>for</strong> "fundamental <strong>and</strong> border sciences of physics", where he founded a committee<br />

<strong>for</strong> rock blasting techniques ( Sw. Samarbetskommittén för bergsprängningsteknik). The purpose<br />

was to create a discussion <strong>for</strong>um <strong>for</strong> fur<strong>the</strong>ring knowledge <strong>and</strong> exchanging experience concerning <strong>the</strong><br />

physical aspects of rock blasting.<br />

The chemical side<br />

While <strong>the</strong> application of explosives <strong>and</strong> o<strong>the</strong>r energetic materials calls <strong>for</strong> good knowledge in physical<br />

<strong>and</strong> mechanical sciences, a deeper underst<strong>and</strong>ing of <strong>the</strong> processes of energy release has to be found in <strong>the</strong><br />

field of chemistry, especially within <strong>the</strong> recalcitrant investigation area of chemical kinetics. This release is<br />

extremely fast, thus <strong>the</strong> term "energetic", so <strong>the</strong> study of <strong>the</strong> chemistry behind it was not – <strong>for</strong> experimental<br />

reasons – really possible in <strong>the</strong> early days. The subject "Combustion <strong>and</strong> flame" ( Sw. Förbränningslära)<br />

was <strong>the</strong>re<strong>for</strong>e more or less excluded from <strong>the</strong> scholarly chemistry. But by <strong>and</strong> by <strong>the</strong> need <strong>for</strong><br />

chemical knowledge arose.<br />

Since <strong>the</strong> academic institutions were of little help, <strong>and</strong> in order to do something about it, people like C.<br />

H. Johansson in Sweden <strong>and</strong> Bernard Lewis in <strong>the</strong> U.S. founded scientific/technical bodies of practitioners<br />

<strong>for</strong> <strong>the</strong> fur<strong>the</strong>ring of relevant knowledge, e.g., by means of conferences <strong>and</strong> colloquia.<br />

Presentation of <strong>the</strong> Swedish "Section"<br />

The Johansson body, or discussion group, called "working group" by him, was founded in 1949 as a<br />

free <strong>and</strong> uncommitted society. Professor Johansson <strong>and</strong> Dr. Lewis knew each o<strong>the</strong>r, so when <strong>the</strong> Combustion<br />

Institute was founded several years later, <strong>the</strong>y decided that <strong>the</strong> Swedish "working group in<br />

<strong>detonics</strong>" in addition should constitute <strong>the</strong> Swedish <strong>section</strong>, or subcommittee of <strong>the</strong> Combustion Institute;<br />

<strong>the</strong> decision to that effect was taken by <strong>the</strong> Institute in 1955, <strong>the</strong> year after its foundation. Originally,<br />

however, <strong>the</strong> word Section was not related to <strong>the</strong> Combustion Institute.<br />

In 1939, <strong>the</strong> Swedish Royal Academy of Sciences, KVA, founded a "national committee <strong>for</strong> mechanics”<br />

(Svenska nationalkommittén för mekanik). This committee was subdivided into a number of "special<br />

<strong>section</strong>s", <strong>and</strong> in 1954 C. H. Johansson’s group was accepted as "<strong>the</strong> special <strong>section</strong> <strong>for</strong> <strong>detonics</strong>"; "<strong>and</strong><br />

<strong>combustion</strong>" was added later, probably when its personality was split <strong>and</strong> it became a <strong>section</strong> of <strong>the</strong><br />

Combustion Institute as well. Later "special" was removed, <strong>and</strong> <strong>the</strong> name "Sektionen för detonik och förbränning"<br />

(The Section <strong>for</strong> Detonics <strong>and</strong> Combustion) was established.<br />

It is doubtful whe<strong>the</strong>r <strong>the</strong> term " <strong>detonics</strong>" was ever properly defined. It may, anyhow, be regarded as a<br />

h<strong>and</strong>y abbreviation of "sciences <strong>and</strong> applications of PEP substances", where "PEP" st<strong>and</strong>s <strong>for</strong> Pyrotechnics,<br />

Explosives, <strong>and</strong> Propellants, alias "energetic materials".<br />

The Section’s "personality"<br />

The Section is very in<strong>for</strong>mal, <strong>and</strong> is run without <strong>for</strong>mal by-laws. Implicit by-laws exist, though. They<br />

are registered in <strong>the</strong> minutes (<strong>and</strong> in 1998 codified as a separate document) of <strong>the</strong> meetings of <strong>the</strong> Working<br />

Committee, in <strong>the</strong> case decisions of this kind were taken. One such by-law states that <strong>the</strong> Section’s "board"<br />

should consist of an unspecified number of engineers, scientists, etc., engaged in production, R&D, <strong>and</strong><br />

application of energetic materials in a broad sense ( i.e., including conventional fuels <strong>for</strong> heat <strong>and</strong> power<br />

production). Ano<strong>the</strong>r one states that <strong>the</strong> Section should be managed by a team – <strong>the</strong> Executive Committee<br />

– consisting of <strong>the</strong> President, <strong>the</strong> Vice-President, <strong>and</strong> <strong>the</strong> Secretary. The appointment of <strong>the</strong>se officers is<br />

<strong>the</strong> responsibility of <strong>the</strong> Working Committee, not of <strong>the</strong> membership at large, <strong>for</strong> which no <strong>for</strong>mal annual<br />

meetings are held. As a consequence, <strong>the</strong> composition of <strong>the</strong> Working Committee – "which when needed


4<br />

renews itself", as <strong>the</strong> codified by-laws state –, <strong>and</strong> especially <strong>the</strong> Executive Committee, tends to be ra<strong>the</strong>r<br />

permanent (vide infra); people are welcome to stay as long as <strong>the</strong>y wish <strong>and</strong> think <strong>the</strong>y can contribute.<br />

This means stability, but not at <strong>the</strong> expense of hampering <strong>the</strong> realization of new ideas; <strong>the</strong> problem, if any,<br />

is ra<strong>the</strong>r to activate <strong>the</strong> members in that respect. Membership is gratis, <strong>and</strong> no fees are paid to <strong>the</strong> officers<br />

of Executive Committee, or to members of <strong>the</strong> Working Committee. All work done is truly idealistic.<br />

All this makes <strong>the</strong> Section a ra<strong>the</strong>r special organization. The Working Committee, <strong>and</strong> especially <strong>the</strong><br />

Executive Committee, supports <strong>the</strong> members by providing <strong>the</strong>m with in<strong>for</strong>mation <strong>and</strong> by arranging<br />

conferences, lectures, courses, etc.<br />

The Swedish Section has more than 280 members, <strong>the</strong>reof 9 % in <strong>the</strong> o<strong>the</strong>r Nordic countries, except<br />

Icel<strong>and</strong>. Members span from people with practical production experience <strong>and</strong> workers in <strong>the</strong> field to<br />

company managers in industry, <strong>and</strong> from students to professors at academic institutions. This span reflects<br />

<strong>the</strong> Sections ambitions: to bridge <strong>the</strong> un<strong>for</strong>tunate gap between <strong>the</strong> world of practical experience <strong>and</strong> need<br />

(“know how”) <strong>and</strong> <strong>the</strong> knowledge-generating, scientific world (“know why”).<br />

The purposes of <strong>the</strong> Section.<br />

The Working Committee corresponds to C. H. Johansson’s original discussion group. The points below<br />

were <strong>for</strong>mulated by this discussion group, <strong>and</strong> are primarily instructions <strong>for</strong> <strong>the</strong> Committee, <strong>the</strong> execution<br />

of which being to <strong>the</strong> benefit of <strong>the</strong> membership at large:<br />

• Supply in<strong>for</strong>mation concerning ongoing investigations per<strong>for</strong>med at domestic as well as at <strong>for</strong>eign<br />

research institutes.<br />

• Arrange contacts between domestic <strong>and</strong> <strong>for</strong>eign research institutes.<br />

• Supply in<strong>for</strong>mation on scientific conferences.<br />

• Supply in<strong>for</strong>mation on scientific <strong>and</strong> technical literature.<br />

• Arrange lectures <strong>and</strong> colloquia on questions of common interest.<br />

• Invite <strong>for</strong>eign scientists to lecture, <strong>and</strong> in connection <strong>the</strong>rewith arrange visits to domestic institutes.<br />

• Organize task <strong>for</strong>ces <strong>for</strong> solving fundamental research problems, measuring problems, etc.<br />

• Fur<strong>the</strong>r educational activities.<br />

In later years, an additional activity took over, viz., <strong>the</strong> arranging of national <strong>and</strong> international conferences.<br />

But this activity is in fact of an overall nature <strong>and</strong> encompasses all <strong>the</strong> original intentions above.<br />

As from 1970, one to three newsletters ( Sw. Meddel<strong>and</strong>en) per year are distributed to <strong>the</strong> members.<br />

With a few exceptions, this is nowadays done electronically. In addition to pieces of general in<strong>for</strong>mation,<br />

such as a list of up-coming conferences, <strong>the</strong> newsletters also contain contributions from <strong>the</strong> members,<br />

debate articles, etc.<br />

The Executive Committee<br />

The number of presidents since <strong>the</strong> foundation more than 50 years ago is only four (4). The number of<br />

secretaries is slightly higher: five. The first vice-president was elected in 1960, <strong>the</strong> fourth in 2003. The<br />

personnel history is given in Appendix 1.<br />

The Working Committee<br />

The function of <strong>the</strong> Working Committee is mainly advisory. It consists of persons with scientific <strong>and</strong><br />

practical experience within <strong>the</strong> Section’s activity areas.<br />

Meetings are held irregularly, one to four times per year, as need may be. The Section is homeless, as<br />

far as real estate is concerned, so <strong>the</strong> meetings are as a rule combined with study visits to PEP- <strong>and</strong> <strong>combustion</strong>-related<br />

companies <strong>and</strong> institutions.<br />

Presently, <strong>the</strong> numerical strength of <strong>the</strong> Working Committee is twelve.<br />

In December 1997, KVA’s national Committee <strong>for</strong> Mechanics discontinued its "special <strong>section</strong>s". This<br />

was un<strong>for</strong>tunate <strong>for</strong> <strong>the</strong> Section, not so much because <strong>the</strong> royal status disappeared, but mainly because <strong>the</strong><br />

Section’s name had become internationally known <strong>and</strong> something of an established trademark. (Changing<br />

into "The Swedish Association <strong>for</strong> Detonics <strong>and</strong> Combustion", or something like that, was felt as detri mental as if


5<br />

<strong>the</strong> Coca-Cola Co. should change its name to "The No. 1 Beverage Co."). But luckily enough, <strong>the</strong> affiliation with<br />

<strong>the</strong> Combustion Institute remains.<br />

Co-operation with <strong>the</strong> Swedish Competence Centre <strong>for</strong> Energetic Materials, <strong>KCEM</strong><br />

The reorientation of military research in Sweden after <strong>the</strong> end of <strong>the</strong> cold war in addition to <strong>the</strong> restructuring<br />

of <strong>the</strong> Swedish military <strong>and</strong> civilian explosives industry meant difficulties <strong>for</strong> <strong>the</strong> Section to get<br />

people to volunteer <strong>for</strong> <strong>the</strong> practical work connected with <strong>the</strong> arranging of conferences.<br />

A good solution to this problem presented itself when <strong>the</strong> Swedish Competence Centre <strong>for</strong> Energetic<br />

Materials, <strong>KCEM</strong>, came into existence on 1 January 2002. A close, in<strong>for</strong>mal co-operation was agreed<br />

upon, which – among o<strong>the</strong>r things – secured <strong>the</strong> continuation of <strong>the</strong> Section’s well-established international<br />

conference series.<br />

<strong>KCEM</strong> resides in Karlskoga, “<strong>the</strong> Nobel town”. It is a non-profit foundation, which counts among its<br />

members various national-defence organisations, universities, <strong>and</strong> manufacturing companies. Some<br />

<strong>KCEM</strong> projects are financed by <strong>the</strong> European Union, EU. Among <strong>the</strong>se projects is a distance-learning<br />

system <strong>for</strong> training personnel engaged in companies manufacturing pyrotechnic <strong>and</strong> explosives products.<br />

Section’s secretary on<br />

<strong>the</strong> occasion of <strong>the</strong> third<br />

disposal conference in<br />

Karlskoga in November<br />

2003.<br />

The Section runs three international conference series dealing with special PEP <strong>and</strong> <strong>combustion</strong> issues,<br />

viz., ageing <strong>and</strong> stability of explosives <strong>and</strong> o<strong>the</strong>r PEP materials, pyrotechnics, <strong>and</strong> (environmentally<br />

friendly) disposal. The conferences constituting <strong>the</strong>se series are:<br />

• The International Symposium on Chemical Problems Connected with <strong>the</strong> Stability of Explosives<br />

(<strong>the</strong> S series, which started in 1967).<br />

• Pyroteknikdagen (The Pyrotechnical Day), (<strong>the</strong> P series, which started in 1969).<br />

• The International Disposal Conference (<strong>the</strong> D series, which started in 1997).<br />

International Symposium on Chemical Problems Connected with <strong>the</strong> Stability of Explosives<br />

This series, <strong>the</strong> " S" series, was started in 1967 by <strong>the</strong> <strong>the</strong>n president, Dr. Jan Hansson, FOA. Being<br />

responsible <strong>for</strong> stability testing of energetic materials, he searched <strong>for</strong> faster <strong>and</strong> more reliable methods.

“Science unites”; Professor Sergej Novikov, Fellow of <strong>the</strong> Soviet Academy of Sciences, Dr. Jacob Savitt,<br />

U.S.A., Professor Momotaro Suzuki, Japan, <strong>and</strong> Dr. Jan Hansson, 1 June 1976, at <strong>the</strong> 4th Stability<br />

Symposium, S 4, at Mölle.<br />

This work led him to introduce thin-layer chromatography <strong>and</strong> micro- calorimetry – <strong>and</strong> an international<br />

communication <strong>and</strong> discussion vehicle.<br />

The S series has become an internationally recognized conference series <strong>for</strong> presenting <strong>and</strong> discussing<br />

new findings concerning, e.g., chemical kinetics <strong>and</strong> test methods related to <strong>the</strong> ageing of PEP materials,<br />

<strong>and</strong> safe h<strong>and</strong>ling of ammunition. Twelve conferences have been held so far; <strong>the</strong> thirteenth takes place in<br />

June 2004.<br />

At <strong>the</strong> outset, participation was based on personal invitation only. This limitation is no longer valid, but<br />

<strong>the</strong> number of participants is never<strong>the</strong>less kept on <strong>the</strong> low side. Depending on <strong>the</strong> capacity of <strong>the</strong> venue<br />

chosen, a typical range is 50-70 participants. This size makes possible one of <strong>the</strong> ingredients of <strong>the</strong> “Jan<br />

Hansson touch”: intimacy.<br />

The degree of "internationality" is ra<strong>the</strong>r high: around twenty countries are, as a rule, represented. In<br />

<strong>the</strong> "cold war" days, <strong>the</strong> series meant a possibility <strong>for</strong> scientists from <strong>the</strong> East <strong>and</strong> <strong>the</strong> West to meet <strong>and</strong><br />

become personal friends. This kind of "match making" was one of Jan Hansson’s distinguishing marks.<br />

He himself had personal friends in many countries, from China to Japan – counted westward. Even if<br />

English was <strong>the</strong> common language, his knowledge in Russian <strong>and</strong> Chinese, in addition to German <strong>and</strong><br />

French, streng<strong>the</strong>ned <strong>the</strong> contacts with <strong>for</strong>eign scientists.<br />

As from <strong>the</strong> 12th Symposium in 2001, future conferences will, in honour of <strong>the</strong> creator, be officially<br />

named " Jan Hansson Symposium on Chemical Problems Connected with <strong>the</strong> Stability of Explosives ".<br />

Future conferences will be arranged in close co-operation with <strong>KCEM</strong>.<br />

Appendix 2 is a list of <strong>the</strong> 302 papers presented so far <strong>and</strong> published in <strong>the</strong> Section’s green-coloured<br />

proceedings volumes. The listing is in alphabetical order by presenter/author.

Traditionally, <strong>the</strong>se conferences start with a welcoming buffet supper Sunday night <strong>and</strong> end <strong>the</strong><br />

following Thursday morning. Monday night, a "socializing" banquet takes place. The banquet is preceded<br />

by some kind of entertainment, usually a folk dancing per<strong>for</strong>mance. A spouses programme is run in<br />

parallel with <strong>the</strong> sessions, except <strong>for</strong> Tuesday afternoon, when a common excursion is arranged.<br />

The pictures below are snapshots from <strong>the</strong> various "S" activities. The tenth Stability Symposium, S 10,<br />

in 1995 meant jubilee celebration. Professor Per-Anders Persson, New Mexico Tech, U.S.A., a collaborator<br />

with Carl Hugo Johansson <strong>and</strong> a long-time member of <strong>the</strong> Working Committee, spoke at <strong>the</strong> banquet<br />

in honour of <strong>the</strong> occasion – <strong>and</strong> of Jan Hansson. The speech is included in <strong>the</strong> S 10 proceedings. Here is<br />

an excerpt:<br />

These symposia have developed, as conceived by Dr. Hansson, into a permanent Swedish<br />

international feature in energetic materials science. Each has a select, limited number of<br />

invited speakers who all stay at <strong>the</strong> same hotel <strong>for</strong> <strong>the</strong> duration of <strong>the</strong> meeting. Each is timed<br />

to coincide with <strong>the</strong> week <strong>the</strong> short Nordic summer is at its most beautiful.<br />

Dr. Hansson has been able to attract <strong>the</strong> best of <strong>the</strong> scientists from around <strong>the</strong> world to<br />

<strong>the</strong>se Symposia. The proceedings volumes, in addition to becoming <strong>the</strong> main economic support<br />

<strong>for</strong> <strong>the</strong> Section, have developed into an important source of high-class in<strong>for</strong>mation about <strong>the</strong><br />

stability of explosives. This has undoubtedly contributed to increased safety in <strong>the</strong> explosives<br />

industry, though no one can count exactly how many accidental explosions have been<br />

prevented <strong>and</strong> how many lives have been saved by <strong>the</strong> work done by Dr. Hansson <strong>and</strong> those<br />

working with him in arranging <strong>the</strong>se unpretentious Symposia on Chemical Problems<br />

Connected with <strong>the</strong> Stability of Explosives.<br />

presented a paper on "experimental studies to produce a composition which is able to resist decomposition";<br />

<strong>the</strong> title is "Composition – Decomposition". The "paper" was presented by a bassoon, a clarinet, a<br />

flute, an oboe, <strong>and</strong> a French horn playing <strong>the</strong> movements "Nitrocellulose", " Nitroglycerine", Diphenyl-


amine", " Centralite" <strong>and</strong> "Jan Robert Hansson", respectively. The score is published in <strong>the</strong> S 7 proceedings.<br />

Pyroteknikdagen (The Pyrotechnical Day)<br />

This series, <strong>the</strong> P series, was also started by Dr. Jan Hansson. The first conference took place in<br />

Stockholm in 1969, <strong>the</strong> 9 th <strong>and</strong> latest one in Lund in 1990. Whe<strong>the</strong>r "last" has to be substituted <strong>for</strong> "latest"<br />

remains to be seen. The decline of pyro matters in Sweden has put <strong>the</strong> Pyro Day in a state of st<strong>and</strong> by.<br />

The first conference was a national – or ra<strong>the</strong>r Nordic – one, with all <strong>the</strong> nine papers presented <strong>and</strong><br />

published in Swedish. At <strong>the</strong> second conference in 1971, five out of seven papers were presented in<br />

Swedish by Swedes but published in English. It was not until 1973 that a non-Sc<strong>and</strong>inavian <strong>for</strong>eigner<br />

appeared <strong>and</strong> started <strong>the</strong> internationalisation of <strong>the</strong> P series; his name was Professor Joseph H. McLain,<br />

President of Washington College, Chestertown, MD, U.S.A.<br />

Appendix 3 (pp. 42-47) lists <strong>the</strong> 84 papers presented <strong>and</strong> published in <strong>the</strong> Section’s red-coloured<br />

International Disposal Conference<br />

The D series, was started in 1997 by Dr. Stig Johansson. With an R&D background in pyrotechnics<br />

(matches), <strong>combustion</strong> <strong>and</strong> flame (disposal of match waste), <strong>and</strong> in <strong>the</strong> management of a CEN (<strong>the</strong><br />

European St<strong>and</strong>ardization Organization) working group on st<strong>and</strong>ardization related to disposal of used<br />

packaging by way of combustive energy recovery, he thought that a <strong>for</strong>um <strong>for</strong> discussing various aspects<br />

of PEP <strong>and</strong> <strong>combustion</strong>-related disposal issues was worth trying. The common scientific feature is<br />

"chemical conversion in self-propagating reaction zones" (an essential component of a strict scientific<br />

<strong>combustion</strong> definition presented by Dr. Johansson at P 1 in 1971, <strong>and</strong> anew at D 1 in 1997).<br />

Of course, <strong>the</strong> idea of merging areas traditionally considered to have nothing in common was<br />

questioned. There<strong>for</strong>e, <strong>the</strong> preface of <strong>the</strong> second proceedings volume may tell why <strong>the</strong> Section decided to<br />

continue <strong>the</strong> series:<br />

The previous International Disposal Conference, held in Lund in November 1997,<br />

was a tentative thing to which we did not dare to assign an ordinal number at <strong>the</strong><br />

outset. Fortunately enough, <strong>the</strong> trial balloon turned out to fly all right, so we took a


13<br />

chance <strong>and</strong> issued <strong>the</strong> collection of papers as Proceedings of <strong>the</strong> First International<br />

Disposal Conference.<br />

Three years later we could notice with relief <strong>and</strong> pleasure that <strong>the</strong> second<br />

conference worked out quite well also, <strong>and</strong> resulted in <strong>the</strong> present “Volume 2”.<br />

Admittedly, joining toge<strong>the</strong>r such diverse zone reaction phenomena as those<br />

connected with <strong>combustion</strong> in incinerators <strong>and</strong> reclamation of items designed to<br />

deflagrate or detonate (e.g., munitions) may seem a bit out of <strong>the</strong> ordinary. But so are<br />

burning <strong>and</strong> flames, detonations <strong>and</strong> explosions, <strong>and</strong>, especially so, environmental<br />

<strong>and</strong> safety problems related to <strong>the</strong>m. Better control requires deeper underst<strong>and</strong>ing of<br />

what is going on, <strong>and</strong> – probably more often than not – thinking along new lines.<br />

Exploring <strong>and</strong> discussing such a common feature as chemical conversion in selfpropagating<br />

reaction zones at large might <strong>the</strong>re<strong>for</strong>e be worth trying. Fur<strong>the</strong>rmore, in<br />

order to speed up <strong>the</strong> refining of available “know how” into “know why” – that is<br />

what scientific research boils down to –, all types of deflagration <strong>and</strong> detonation<br />

processes should be studied <strong>and</strong> analysed toge<strong>the</strong>r. Here bits <strong>and</strong> pieces of <strong>the</strong><br />

immense body of practical experience constitute <strong>the</strong> necessary vehicle. Many speakers<br />

rode it.<br />

A new feature this time was <strong>the</strong> self-ignition <strong>the</strong>me, a <strong>the</strong>me that light was thrown<br />

upon from different angles : <strong>the</strong>ory, cases, <strong>and</strong> practical demonstration. Underst<strong>and</strong>ing<br />

<strong>the</strong> nature of zone reactions should, of course, include an underst<strong>and</strong>ing of how<br />

<strong>the</strong>y come about, i.e., of <strong>the</strong> ignition process, self-ignition being <strong>the</strong> most treacherous<br />

<strong>and</strong> insidious one.<br />

As long as fires, emission of stack gas, h<strong>and</strong>ling of explosives, etc., continue to<br />

bo<strong>the</strong>r mankind <strong>and</strong> <strong>the</strong> environment, especially in connection with disposal <strong>and</strong><br />

demilitarisation processes, we will try to continue <strong>the</strong>se interdisciplinary-based conferences.<br />

The second conference was held in Linköping. The third, which was held in Karlskoga in 2003, was a<br />

success beyond all expectations. In fact, <strong>the</strong> three years interval has been questioned – it is too long.<br />

Survey of Combustion Research in Sweden<br />

This conference was held at <strong>the</strong> Chalmers University of Technology ( CTH) in Go<strong>the</strong>nburg 21-22<br />

October 1998. It consisted of eight plenary lectures <strong>and</strong> 61 poster presentations <strong>and</strong> had ga<strong>the</strong>red 108<br />

participants, of <strong>the</strong>m 107 from Sweden.<br />

This conference was meant to be <strong>the</strong> start of a " C" (<strong>for</strong> "<strong>combustion</strong>" of non-PEP fuels) series, but <strong>the</strong><br />

C people preferred to go <strong>the</strong>ir own way <strong>and</strong> founded <strong>the</strong> Nordic-Sc<strong>and</strong>inavian Section of <strong>the</strong> Combustion<br />

Institute in 1999.<br />

(Geographical note: according to <strong>the</strong> Swedish National Encyclopaedia, <strong>the</strong> Nordic countries are five:<br />

Denmark, Finl<strong>and</strong>, Icel<strong>and</strong>, Norway, <strong>and</strong> Sweden. Sc<strong>and</strong>inavia sometimes st<strong>and</strong>s <strong>for</strong> Denmark, Norway,<br />

<strong>and</strong> Sweden, sometimes <strong>for</strong> <strong>the</strong>se three countries plus Finl<strong>and</strong>, <strong>and</strong> finally <strong>for</strong> <strong>the</strong> Sc<strong>and</strong>inavian peninsula,<br />

i.e., Norway <strong>and</strong> Sweden. Inappropriately, <strong>the</strong> five Nordic countries are now <strong>and</strong> <strong>the</strong>n called Sc<strong>and</strong>inavia.)<br />

The 16th International Pyrotechnics Seminar<br />

The subject conference was arranged by <strong>the</strong> Section in "<strong>the</strong> Match Town of <strong>the</strong> World", Jönköping, in<br />

1991. This was a big commitment that required <strong>the</strong> involvement of Jönköping’s commercial conference<br />

<strong>and</strong> exhibition centre, Elmia. Twenty countries were represented with a total of 158 participants. Dominating<br />

countries were, in order of magnitude, Sweden, U.S.A., U.K., <strong>and</strong> France.

At <strong>the</strong> exhibition, which was run in parallel with <strong>the</strong> conference by Elmia, <strong>the</strong> Swedish Match Co. saw<br />

to it that Jönköping could live up to its nickname “<strong>the</strong> Match Town of <strong>the</strong> World” by presenting an<br />

entirely environment-friendly match: no sulphur, no hexavalent chromium in <strong>the</strong> head composition. This<br />

match has been on <strong>the</strong> market ever since.<br />

Joint European Combustion Symposia<br />

1992: Toge<strong>the</strong>r with <strong>the</strong> French <strong>and</strong> <strong>the</strong> Italian <strong>section</strong> of <strong>the</strong> Combustion Institute, <strong>the</strong> Swedish<br />

Section organized a joint <strong>combustion</strong> symposium held on Capri, Italy, 21-24 September 1992.<br />

1996: Toge<strong>the</strong>r with <strong>the</strong> Portuguese, British, <strong>and</strong> Spanish <strong>section</strong> a similar <strong>combustion</strong> symposium was<br />

organized; it was held in Funchal, Madeira, 27 July – 2 August, 1996.

Task Forces<br />

Task <strong>for</strong>ces <strong>for</strong> dealing with actual problems have been appointed on an ad hoc basis from time to<br />

time. Typical questions of common interest have been selection <strong>and</strong> st<strong>and</strong>ardization of test methods <strong>for</strong><br />

PEP materials, <strong>and</strong> studying <strong>and</strong> commenting on new legislation proposals concerning fireworks <strong>and</strong><br />

pyrotechnics in general.<br />

The 1960s: Working groups <strong>for</strong> establishing st<strong>and</strong>ardized test methods <strong>for</strong> explosives.<br />

1974: Investigatory <strong>and</strong> examination work <strong>for</strong> <strong>the</strong> purpose of extending <strong>the</strong> Section’s activities in <strong>the</strong><br />

field of energy production by way of "ordinary" <strong>combustion</strong> (boilers, internal-<strong>combustion</strong> engines, etc.).<br />

The aim was to appoint an engaged vice-president with <strong>the</strong> pronounced object to develop <strong>the</strong> Section’s<br />

<strong>combustion</strong> area. Combustion research in Sweden in those days was, however, less extensive; in retrospect<br />

<strong>the</strong> idea was obviously a quarter of a century ahead of its time.<br />

1975: Study <strong>and</strong> discussion of a draft law <strong>for</strong> "regulating <strong>the</strong> pyrotechnical field with regard to public<br />

life". The problem behind this was display accidents <strong>and</strong> nuisance (driving dogs <strong>and</strong> old folks crazy with<br />

loud crackers, blasting people’s mail boxes, etc.) connected with fireworks. The task <strong>for</strong>ce’s verdict was<br />

passed on to <strong>the</strong> law makers.<br />

Publications<br />

The Section has published – <strong>and</strong> sold – proceedings from all <strong>the</strong> conferences, symposia, <strong>and</strong> colloquia<br />

ever run by <strong>the</strong> Section (see Appendix 6). In addition, <strong>the</strong> Section has translated Professors Andrejev’s<br />

<strong>and</strong> Beljajev’s Theory of Explosives (item No. 4 on <strong>the</strong> list), which appeared in Russia in 1960, from<br />

Russian into German. The German translation was published in 1964 by Erwin Barth Verlag in Germany.<br />

Travelling Grants<br />

The Section has given travelling grants to students <strong>and</strong> young scientists <strong>for</strong> enabling <strong>the</strong>m to participate<br />

in international conferences. The recipients <strong>and</strong> <strong>the</strong> conferences <strong>the</strong>y went to are listed in Appendix 7.<br />

In 1983, <strong>the</strong> Working Committee decided that <strong>the</strong>se grants should be named Carl Hugo Johansson<br />

Travelling Grant in honour of <strong>the</strong> Section’s founder.<br />

"Back to <strong>the</strong> Future"<br />

The Swedish Section of <strong>the</strong> Combustion Institute will continue its traditional activities in <strong>the</strong> areas of<br />

energetic materials <strong>and</strong> <strong>combustion</strong> of ordinary fuels, <strong>the</strong>reby spanning all aspects from practical applications<br />

<strong>and</strong> experience to academic research work. One of <strong>the</strong> tasks of <strong>the</strong> latter is to elevate practical<br />

observations to applicable knowledge (know why). To judge from <strong>the</strong> endless occurrence of explosion <strong>and</strong><br />

fire accidents around <strong>the</strong> world, better <strong>and</strong> deeper underst<strong>and</strong>ing <strong>and</strong> knowledge of <strong>the</strong> fundamentals of<br />

self-propagating reaction zones, especially ignition, are no doubt required.<br />

The executive responsibility <strong>for</strong> <strong>the</strong> Stability conference series, though, will as from S 13 in 2004 be<br />

taken over by <strong>KCEM</strong>, while <strong>the</strong> Section is responsible <strong>for</strong> <strong>the</strong> scientific content.<br />

The need <strong>for</strong> a purely <strong>combustion</strong>-oriented, academic organization led to <strong>the</strong> foundation of <strong>the</strong> Nordic-<br />

Sc<strong>and</strong>inavian Section of <strong>the</strong> Combustion Institute in 1999. This distribution of <strong>the</strong> work means increased<br />

strength in <strong>the</strong> PEP, i.e., energetic materials, <strong>and</strong> <strong>combustion</strong> areas, respectively. Fruitful co-operation is<br />

provided <strong>for</strong> by exchange of board members. An example of a “non-PEP” <strong>combustion</strong> issue fur<strong>the</strong>red by<br />

<strong>the</strong> Section is combustive energy recovery of household <strong>and</strong> industrial waste, which is a very complex fuel<br />

requiring advanced <strong>combustion</strong> <strong>and</strong> environmental-oriented cleaning techniques.
