DZL seires coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.), it is honored as Chinese famous brand. This series boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically and strong adaptability of different fuels. The fuel could be II class bituminous coal, the diameter should be 6-25mm, and ash content should be less than 32.4%. Otherwise, DZL series boiler could also burn biomass fuel, including wood, straw, bagasse, rice husk, coconut shell, cotton seeds, peanut shell, etc.

Technical Parameters

Features of DZL Series 3 Pass Biomass Wood Coal Fired Steam Boiler

Advantage of coal steam boiler

1. stably maintain biomass gasification combustion and suspended combustion, flue gas in the high temperature furnace stay for a long time after times air distribution, full combustion, high fuel utilization, no black smoke.

2. The dust, carbon dioxide, sulfur dioxide and other environmental indicators are better than the national emission standards, conforming to the current international emission reduction policies, the environmental protection department approved the use of the boiler in a city environmental protection area.

FAQ

1.What are the spare parts for DZL/SZL series coal/biomass fired boiler?

Generally, the spare parts are instrumentation valve, grate plate, gasket, etc.

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 completed.
2.The thermal efficiency is higher than the vertical boiler,
3.Horizontal type: less thermal loss, stronger output, and higher steam quality.

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
