Product Name: Coal/Biomass/Rice Husk/Coco Nut /Bagass/Solid Wood Fired Steam Boiler Model NO.: DZL1, 2, 4, 6, 8, 10 Usage: Industrial Burning Style: Chamber Combustion Boiler Manufacturing Level: A Pressure: High Pressure Drum Placement: Horizontal Boiler Water Circulation: Forced Circulation Media: Steam Structure: Fire Tube Installation: Packaged Boiler Fuel: Coal-Fired Function: Water Boiler, Steam Boilers Trademark: QD Hammer Transport Package: Naked by 40' Ot or Flat Rack Containers Origin: Qingdao HS Code: 84021900 Product Description DZL series coal fired boiler is single drum water-fire tube boiler, chain grate type. Water wall tubes at left and right sides of furnace are the radiated heating area. it has two wings at furnace and screw fire tube in the drum are convection heating area. The upper drum, water wall tube and its heads are in symmetrical arrangement mode. This why furnace structure is in reasonable arrangement and high efficiency. This series boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.This boiler uses the new scientific achievement, such as arch tube plate and corrugated tube, to solve the problem of tube plate flaw and water wall tube explosion, improve the heat transfer efficiency and thermal efficiency, increase the output. The boiler is wide adoptability of different fuels, such as coal, biomass fuel, wood, straw, bagasse, rice husk, coconut shell, etc.DZL Series Steam Boiler SpecificationBoiler ModelDZL2-0.7/1.25/1.6-AIIDZL4-1.25/1.6/2.5-AIIDZL6-1.25/1.6/2.5-AIIDZL8-1.25/1.6/2.5-AIIDZL10-1.25/1.6/2.5-AIIDZL20-1.25/1.6/2.5-AII.Rated Evaporation Capacityt/h24681020Operation PressureMpa1.25/1.61.25/1.6/2.51.25/1.6/2.51.25/1.6/2.51.25/1.6/2.51.25/1.6/2.5Steam TemperatureºC170/194/204194/204/226194/204/226194/204/226194/204/226194/204/226Water-inlet TemperatureºC202020105105105Boiler Heating Efficiency %≥78≥78≥80≥80≥80≥82Area of Stokerm23.25.147.49.611.423.15Coal Available II type bitumite, low heat capability:17700-21000KJ/kgWater PumpModel1½GC5×71½GC5×72GC-5×62½GC6×6DG12-25×7DG25-35×5Motor PowerKW5.5/7.5/117.5/11/18.515/18.515/18.518.5/2230/37Blast FanModelG6-41-13NO5.4AG6-41-13NO6.4AG6-41-13NO7.1AG6-41-13NO8.5AG6-41-13NO8.5ATG20-1Ventilation m³/h4358-23107358-359610354-539418137-936918137-936732079Wind PressurePa994-12541181-14361697-22702535-33912535-33912559Motor PowerKW35.57.518.518.537Induced Draft FanModelY6-41-13NO5.4CY6-41-13NO7.1C1Y6-41-13NO10CY6-41-13NO11.2DY6-41-13NO11.2DGY20-15Ventilationm3/h8901-435015219-817132144-1660741773-2157841773-2157873308Wind PressurePa2568-32402454-32832574-34442764-36972764-36973515Motor PowerKW1122374555110Dimensions of Biggest Parts for ShipmentM5.82×2.1×3.26.5×2.66×3.526.7×3×3.548.0×3.2×3.588.45×3.2×3.5810×4.8×3.55Weight of Biggest Parts for ShipmentT18/19/2027/29/3132/33/3442/43/4445/47/4930/31/32Remark: This parameter is just for reference, for exact parameter,subject to our drawings.Technicaladvantages1.Wingflue can cooldownsmokeinhightemperaturetubesheet,avoidsubcooledboiling, reduceboilerbottomheatload,avoidtubesheetcrack,avoiddrumdeformation.2.Archtubeplate can Improvetubesheetflexibility,reduceweldingseamthermalstress. remove braceandavoidtubesheetcrack.3.Thread tube can enhanceheattransfer,reducedrumsize,improveflexibility, reduceweldingseamthermalstress.DesigncharacteristicsSootinertialseparationdeviceissetinsideboilerandBigvolumenaturalsedimentationchamberissetonthereararchtop.Smokeflowspeedsisslowhere,someparticlesinthesmokecanbeseparatedoutbecauseofgravity.Thesmoketurnsfastattheheadofwingflue,andmanyparticlesareseparatedoutbecauseofinertia.Itlowsoriginalemissionconcentration.Theashinthereararchcanfallonthegratebyashfallinghole,thenberemoved,whichdecreasessecondarypollution.Theboileroperateswellandturnsoutthattheoriginalemissionconcentrationislessthan2000mg/Nm³.Besides,withtheequippedhighefficiencydustcollector,theboileremissionconcentrationsatisfiesnational1-classstandard.Theintenseradiationfurnacearchcanformreasonable'A'stylefiretopromptthecombustion.Watercoolingwallformsfurnaceuponthegrate.Itisbigenoughtoburnthecoalcompletely.Thereasonablearcharrangementensuresflowspeed.Meanwhile,theinsidethreadsmoketube,highefficientburningdevice,well-designedarchesandhighqualityinsulationmaterialsandothercharacteristicsensuretheboilerthermalefficiencyishigherthannationalstandard.
