<strong>Weishaupt</strong> industrial burners<br />
WK40 to WK70<br />
for combustion air temperatures up to 250°C<br />
1/2000 CA
General<br />
<strong>Weishaupt</strong> WK type industrial<br />
burners were developed to meet<br />
special industrial and commercial<br />
requirements. The burners are<br />
suited for operation with or<br />
without preheated combustion air<br />
as required. Very high flue gas<br />
temperatures occur on many<br />
industrial processes (e.g. thermal<br />
fluid boilers) due to the high<br />
media temperatures. A<br />
considerable amount of energy<br />
can be recovered from the hot flue<br />
gases by using a heat exchanger<br />
in the flue gas system to recover<br />
the heat. This technology can<br />
result in improvements in<br />
efficiency of up to 8%.<br />
The burners are also often used on<br />
installations without preheated<br />
combustion air. Reasons for this could be<br />
as follows:<br />
● The customer requires a separate<br />
combustion air fan.<br />
● An industrial burner is specified.<br />
● The resistances in the heat exchanger<br />
are too high to use a monobloc burner.<br />
● The combustion rating is too high to<br />
use a monobloc burner.<br />
Burner types WK40 and WK50<br />
Burners operating with preheated<br />
combustion air are supplied with an<br />
insulated burner housing and a coolingair<br />
fan unit, for which a separate coolingair<br />
fan is supplied. An oil pump is fitted<br />
on oil and dual fuel (oil/gas) burners and<br />
residual oil burners are further equipped<br />
with an electric preheater. On request,<br />
the WK 40 burner can be supplied with a<br />
separate pump and preheater assembly -<br />
this is often the case with industrial<br />
installations. The burner housing is not<br />
insulated for burners operating at normal<br />
combustion air temperatures.<br />
Burner type WK70<br />
Burners operating either at normal<br />
combustion air temperatures or with<br />
preheated combustion air are both fitted<br />
with internal insulation as standard. For<br />
burners operating at normal combustion<br />
air temperatures the internal insulation<br />
serves as a sound absorber and<br />
consequently the burner noise level is<br />
below 85 dB(A). The pump and<br />
preheater assembly is supplied<br />
separately.<br />

Insulated burner housing for<br />
preheated combustion air<br />
The insulation of the burner housing<br />
prevents the emission of temperature<br />
and noise. Even with combustion air<br />
temperatures of 250 C, the surface<br />
temperature of the housing is less than<br />
100 C. On WK40 burners the oil pump<br />
and, where applicable, the oil preheater<br />
are fitted away from the burner housing<br />
and are thus protected from the heat. A<br />
separate cooling air fan is supplied to<br />
cool the control unit and the flame<br />
monitoring device.<br />
Tried and tested components<br />
Sizes 50 to 70 have the same mixing<br />
assembly as is used on the size 50 to 70<br />
Monarch burners.<br />
Simple maintenance<br />
Diffuser, ignition electrodes and the gas<br />
mixing assembly are easily accessible<br />
when the cover is opened. The flame<br />
tube can also be taken out through the<br />
opening in the housing once the mixing<br />
assembly has been removed. The oil, gas<br />
and air regulating components are neatly<br />
arranged and are easily accessible.<br />

The oil burners fire distillate and residual<br />
fuel oils to DIN 51 603 with a viscosity<br />
up to 6 mm 2 /s at 20°C (distillate oil EL)<br />
or 50 mm 2 /s at 100°C (residual oil S).<br />
The gas and dual fuel burners are tested<br />
for use with the following gases to EN<br />
437 and DVGW Worksheet G260/I:<br />
natural gas E (formerly designated<br />
natural gas H) and natural gas LL<br />
(formerly designated natural gas L), as<br />
well as liquid petroleum gas.<br />
General<br />
Standard execution burners (material,<br />
construction and protection) are<br />
designed for operation indoors within a<br />
temperature range of -10°C to +40°C<br />
(details on special measures for oil<br />
storage in sub-zero temperatures and on<br />
operation outdoors are available on<br />
request). There are various special<br />
executions available on request, such as<br />
additional equipment to comply with TRD<br />
<strong>604</strong> or new technologies such as<br />
electronic compound regulation (ECR),<br />
O 2 trim and speed control.<br />

Description<br />
Regulation<br />
The burners alter their capacity<br />
proportionally, depending on the heat<br />
requirement. Depending on the type of<br />
control the burner is either:<br />
■ sliding two stage (basic version)<br />
■ modulating<br />
The servomotor run time between partial<br />
and full load is 42 seconds. With sliding<br />
two stage regulation, the partial and full<br />
load positions are fixed within the<br />
regulating range. Depending on heat<br />
demand, the burner slides to one load<br />
point to the other, thus preventing rapid<br />
cycling.<br />
By fitting a suitable controller into the<br />
control panel the standard sliding two<br />
stage burner can be fully modulating.<br />
Modulating burners operate at any load<br />
point within the burner range, depending<br />
on the heat required.<br />
WKGL40/2-A<br />
Increased safety due to nozzle head<br />
shut off device with nozzle solenoid<br />
A type tested shut off device is fitted in<br />
the nozzle and shuts off the oil flow<br />
directly in the nozzle orifice. No fuel oil<br />
can leave the nozzle head, thus<br />
increasing safety.<br />
Nozzle recirculation on residual oil<br />
burners<br />
During prepurge on residual oil burners,<br />
heated oil circulates through the nozzle<br />
and oil line system so that on flame<br />
establishment the oil is at the correct<br />
temperature.<br />
Precise oil temperature regulation<br />
with a <strong>Weishaupt</strong> oil preheater<br />
<strong>Weishaupt</strong> residual oil burners are fitted<br />
with oil preheaters, which maintain the<br />
preheated temperature and thus the fuel<br />
viscosity constantly at the desired set<br />
value. This results in uniform atomisation<br />
and combustion efficiency.<br />
WKGL40/2-A<br />
Flame supervision<br />
The burner control box, which is fitted in<br />
the control panel, sequences burner<br />
operation automatically. It monitors the<br />
flame by means of a flame sensor.<br />

The full-tone and half-tone areas together show the total ratings<br />
range. When sizing burners ensure that the required nominal rating<br />
lies within one of the full-tone areas.<br />
The capacity ranges are based on an installation altitude of 500 m<br />
above sea level.<br />
