Weishaupt dual fuel burnersSizes 30 to 70Version NR (NO X -reduction on gas operation)1/2003 CA

DescriptionWeishaupt burners of sizes 30 to 70 were specially designed and developed forindustrial applications. The Monoblock-Burners are characterized with multipleexcellent features such as:• Big firing range and wide area of applications• Stable air fan performance – excellent combustion characteristics• Burner casing can be swung opened• Easy to install, setup and maintenance• Air damper closed off during burner stop• Oil pump and electric oil heater is standard for heavy oil burnersControlControl of air and fuel is performedaccording to the fuel type, burner sizeand requirement:• Two and three stageThe oil part of the dual fuel burnerhas a nozzle head with two or threenozzles. The capacity regulation isachieved by opening or closing the oilsolenoid valves 2 and 3 with correspondingchanges in air amount.• Sliding two stageOn sliding two stage regulation, thelow fire and high fire points are assignedwithin the control range. Theburner slides depending on heat requirementbetween both operatingpoints. There is no sudden increase ordecrease of supplied fuel amount.• ModulatingModulating burners operate accordingto the heat requirement at any operatingpoint within the control range.Reduced starting capacityThe burner starts at ignition position viaseparated pilot line. This way only asmall amount of gas flows into the combustionchamber. After a certain delaytime the burner operates in low fire.Controlled shutdown from low fireControlled shutdown of the burner isperformed only at low fire. Sudden pressuresurge in the gas supply line can beavoided.Fuel – air ratioThe regulation of fuel to air ratio variesdepending on the burner model:Size 30Burner models RGL and RGMS:Pressure side air regulation via ratio controlledsliding sleeve in the mixing headBurner model GL: Pressure side air regulationvia adjustable flame tube accordingto the firing rate2Sizes 40 to 70Burner models GL, RGL and RGMS:Pressure side air regulation via ratiocontrolled sliding sleeve in the mixingheadHeavy oil burnersHeavy oil burners are equipped with oilpreheaters, which keep the oil atrequired temperature to guaranteeproper viscosity for good atomization.A temperature monitored sequenceprogram circulates the preheated oilto the nozzle head before start andtherefore keeps the nozzles at the sametemperature.Gas trainAs standard, Weishaupt gas and dualfuel burners are always equipped withtwo main gas valves.Gas train can be built according to mostapplicable North American codes andstandards.Digital combustion managerW-FM100 and W-FM200 combustionmanager control all essential burnerfunctions, e.g. fuel and air supply andmonitor the flame with digital precision.The target is optimization of operatingconditions, maximization of economicalaspect and minimizing the emissions.Thanks to the digital combustion technology,such optimization is availabletoday at reasonable cost. Expenses forinstallation and maintenance are evenclearly lower than with conventionaltechnologies. For example, a separateremote panel is no longer required forburner control. Furthermore, remoteoperation, remote diagnostic and remotemonitoring of the appliances are nowrealizable. This increases the safety andcomfort for operator.ApplicationsThe burners can be used with heatexchanger such as boilers, air heatersand for certain process applications.Due to the fact that the burner iscapable of overcoming high combustionchamber pressure, they are most compatiblewith modern high performanceboilers.FuelsOil sectionLight oil (#2 oil), viscosity 6mm 2 /s at68F (20°C)Medium to heavy oil (#4 to #6) with viscosityup to 50mm 2 /s at 212F (100°C)Gas sectionNatural gasPropane (LPG)Installation locationThe burners are designed for indooroperation with temperature of 5F(–15°C) up to 100F (+40°C) and relativehumidity of max. 80%CertificationThe burners are in compliance with mostapplicable European and NorthAmerican standardsExcellent serviceWeishaupt has a high density sales andservice network all over the world.

The advantages ofdigital combustion managementControl and Display UnitDigital combustion managementmeans optimum combustion figures,continuous repeatability of settingvalues and ease of use.Weishaupt burners are equipped withelectronic ratio controller and digitalcombustion management to satisfy therequirements of modern combustiontechnology, which demand a precise andcontinuously reproducible supply of fueland combustion air. Only in this wayoptimal combustion figures can beensured over extended periods of time.If required, the burners can also beequipped with O 2 trim* and variablespeed control.Error free operation via AZL displayand control unitSetting and control of the burner functionsare achieved using a control anddisplay unit, the AZL, which is equippedwith an LCD display. The AZL is connectedto the combustion manager via asafety bus system and can be positionedanywhere according to the user’spreferences within 325 ft. (100 m) distancefrom the burner.Flexible communication possibilitiesThe integrated communication interfaceenables all necessary information andfunctions to be transmitted to a BMSsystem. If required, remote operation andremote diagnosis functions, which areaccessible via modem, can be installed(e.g. oil/gas change-over, adjustment ofsetting values).Communication with external systemsvia BUSIf data has to be exchanged betweenburners and other heating systems withPLC devices, the information can beaccessible via eBUS or MODBUScommunication system.Integration with building managementFor control and management functions,Weishaupt offers ProGraf NT - asoftware product that provides a realtime solution to meet all requirements.The price advantage of the newtechnologyWith improved technology and ease ofuse, combustion plant is becoming evenmore economical than ever before.• No additional burner controls arerequired, since this function is alreadygoverned by the combustion manager.Fuses and burner motor starter are theonly additional items required.• Less installation work means lesserrors: the burners are tested as acomplete unit at the factory.• If required, the W-FM 100 is availablewith an integrated modulating controllerand variable speed module. Noseparate equipment is required. Themodulating controller and variablespeed module are included as standardwith the W-FM 200.• Commissioning and service worktakes less time. The initial presettingof the burner is carried out at the factory.On site, only the site specificoperating points have to be adjusted.• To facilitate O 2 trim, only an O 2 probeand O 2 module have to be installedand connected with the W-FM 200via the internal safety BUS.* In conjunction with W-FM 200 combustionmanager4

Proven quality in detailIncreased safety via shut offassembly with solenoidvalveThe electromagnetic actuated safetyshut off device isolates the oil supply andreturn on burner models RGL40 to 70and RGMS30 to 70 when the burnershuts down. Oil shut off directly at thenozzle ensures a drip free burner shutdown. (Burner type RGL30 uses asystem without nozzle shut off).Considerable noisereduction due to soundabsorbing air inletBy utilizing sound absorbing materials onthe fan suction side it has been possibleto reduce operational noise considerably.Cut-away view of a nozzle shut of assemblyPressure side air regulationvia mixing head with ratiocontrolled sliding sleeveCut-away view of the fan housingThe forward and reverse movements ofthe regulating sleeve in the mixing headensure that the air supply gap is correctat every operating point throughout thecapacity range. This results in optimumvelocities over the whole range ofregulation. With this system, the mixingpressure is increased at low fire,improving the mixing effect of fuel and air.This results in a reduction in excess airand improved combustion efficiency dueto the constant air/fuel ratio.Turn down ratio up to 1:5Turn down ratio up to 1:3Burner sizes 40 to 70 with pressure side ratio controlled sliding sleeveBurner without pressure side sliding sleeveExample of turn down ratio for different burner models6

Pump and preheater stationsDescriptionScope of delivery - pump stationsPump unit (screw spindle pump withmotor), pressure gauge, vacuum gauge,pressure regulating valve, ball valves,suction flange, pressure flange includingcounter flanges, screws and washers,suction-side filter. All parts fullyassembled on an oil drip tray.The pump station is available in twodifferent versions - either as a singlestation unit with one pump, or as a twinstation unit with two pumps, one pumpbeing a backup unit. Should one of thepump fail, it is possible to quickly switchover to the other one.Only proven makes of pump are used.The pumps are carefully matched to thecapacity of the burner.Scope of delivery - preheater stationsPreheater stations are supplied fullyassembled on an oil drip tray. Thepreheater ensures a constant oiltemperature and as result, theappropriate viscosity of the fuel oil.There are two basic versions of thepreheater station available:1. Electric preheating (model WEV...)2. Medium preheating (model MV...)MV.. medium oil preheaterMedium preheaters are high capacity,forced circulation heat exchangers. Highcapacity is achieved with a compact,space saving construction. Hot water,steam or thermo fluid can be used asheating medium. The oil preheatersguarantee substantially stable oiltemperatures and thus good combustionfigures. The oil temperature achieveddepends on the heating medium used.When selecting and sizing, please referto the oil temperature diagrams inchapter 5.3 of the technical brochure“Weishaupt electric and medium oilpreheaters”, print No. 18. Weishauptmedium oil preheaters can be useduniversally. It is possible to change themedium at any time. The mediumpreheater can be used either as standalone unit or in conjunction with anelectric oil preheater.If operating steam at more than 110 PSI(7.5 bar) or hot water between 355F(180°C) and 390F (200°C) iscontinuously available, then an electricpreheater is not required. This is alsopossible if plant with the above minimumpressures or temperatures to beoperated with light oil or gas.If the medium temperature is notsufficient to adequately preheat the fueloil, then the electric oil preheater inputsthe additional heat required. The electricoil preheater heats the oil for the start upof the plant. If the required mediumtemperature is available then the stationswitches over to the medium oilpreheater thus saving on electricity.Suitable connection types for medium oilpreheaters can be selected, dependingon the medium available. If medium oilpreheaters are provided without electricoil preheaters, a mechanical temperatureregulator must be used with the mediumconnection fittings.Air / gas separators or oil circulationtanksPatented air / gas separators orcirculation tanks are always required andmust be quoted with the burner.By using an air / gas separator orcirculation tank, it is possible for thepreheated oil from the burner return to bemixed with oil from the burner supply line.This results in an energy saving, as it isonly necessary to partially heat the fueloil.Where one burner is operating on lightoil, it is then possible to use a two pipesystem so long as the suction vacuumdoes not exceed 6 PSI (0.5 bar). Ifseveral burners with air / gas separatorsor oil circulation tanks are being suppliedby a ring main system, then it is a goodidea to provide a manually actuateddouble shut off device with limit switchimmediately after the air / gas separatoror circulation tank. The air / gasseparator or circulation tank must beselected according to the ring mainpump rating and the burner size. Whenchoosing ring main pump units, pleaseensure that the capacity is around 1.5 - 2times of the nozzle rating.General instructionsWhen starting a boiler from a coldcondition with residual oil, the capacity ofelectric oil preheater must be at least30% of the boiler rating. On hot waterboilers up to 265F (130°C) operatingtemperature, the electric oil preheatersmust be able to produce the full boileroutput without utilizing mediumpreheaters. Use of a medium preheater isnot suitable for medium temperaturesbelow 212F (100°C). The number ofmedia oil preheaters to be selecteddepends on the oil throughput and canbe taken from the capacity charts (seethe technical brochure “Weishauptelectric and media oil preheaters”).Planning and installation instructionsAir /Gas separator, circulation tank,pump station and oil preheater stationmust be installed close to the burner aspossible.On RGMS type burners, sizes 60 and70, the time required for oil circulationduring start sequence depends on thelength of the pipework between theburner and the air gas separator orcirculation tank.The shorter the pipeline, the shorter theperiod between call for heat and oilrelease / burner start after a controlledshutdown.18
