Professional Industrial Coal And Biomass Pellet Fired Steam Boiler
for plastic foam
This steam boiler adopt chain grate,suitable for molding pellet
fuel,can add a small amount of wood,wood block,also can burn with
This boiler adopt the newest achievements in scientific research,
such as:Arched Tube plate, thread smoke tube etc, solve the tube
plate crack of shell type boiler, Water wall tube burst, low
efficiency, insufficient of power,Poor pf coal type adaptability

(M pa )
1. Designed with horizontal, three passes, all-wet back structure.
2. Fire tubes are surrounded by water, and these design making
efficient up to 80%
3.Threaded tube: Strengthen the heat transfer, increase the boiler
4. Big combustion room design: increase furnace heating area,
decrease boiler size, and reduce the emission of the Nox Corrugated
hearth make the boiler safer.
5.Adopting water seal eliminate slag, slag through grate drop into
1.With efficient special designed spirally corrugated tube----Making boiler’s actual capacity is 10-15% higher than name plate
2.It uses new hearth with large volume, ----Improving boiler efficiency,reducing fuel consumption in
3. Most advanced technology for arch ---- Boiler's hearth has a dust separation reversing chamber,it
ensures that the original dust discharge concentration is
4.Optimally designed steam separator ----facilitates vapour gravity separation,and makes the steam
humidity lower than 1%, obviously lower than international standard
This is Applied for Textile Mill,Food and
Beverage,Chemical,Medicine,Light Industry,Rubber,Printing and
Dyeing Plant,Paper Mill,Wood Processing,Garment and Laundry etc.
1.What are the spare parts for DZL/SZL series coal/biomass fired
Generally, the spare parts are instrumentation valve, grate plate,
2.What are the differences between vertical type boiler and
horizontal type boiler with the same capacity?
1.Structure of vertical boiler is compact, occupy a limited area,
2.Convenient on installation and removal.
3.Low cost and investment on capital construction. Steam exhausted
fast and sufficient.
1.The combustion space of horizontal is big, fuel can be burned
2.The thermal efficiency is higher than the vertical boiler,
3.Horizontal type: less thermal loss, stronger output, and higher
3.What are the limitation (size, humidity, chemical element
concentrations) of coal fuel/solid fuel/wood fuel?
Size requirement of coal:6-25mm
Size requirement of blending coal: <50mm (the coal less than 6mm
should less than 30%)
Diameter of biomass particle: 6~10mm, length: 25~50mm, water
content < 15%, ash content < 2%, sulphur content<0.07%,
chlorinity <0.07%, nitrogen content < 0.5%
4.What is the size of furnace door and blower hopper?
Size of furnace door:
Standard elliptical furnace door:300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500
