Company Profile
Product Details
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.

Features of DZL Series 3 Pass Biomass Wood Coal Fired Steam Boiler
| Advanced Design and Configuration | Function / Advantage |
| New Dust Collection | Achieve almost zero pollution |
| Smoke and Dust Separation Chamber | Decrease the original emission concentration of smoke |
| Splayed Wall | Has the function of dust suppression, protect environment |
| Small Scale Flaker Type Grate | New metallurgy formulate make the grate withstand high temperature more than 1600℃, make sure running without stop even when repair. |
| Spirally Corrugated Tube | Improve heat transfer coefficient, thermal efficiency increase to 83%. |
| Airfoil Shaped Flue | Decrease the flue gas temperature in the area of high temperature tube plate, prevent tube plate cracking and swell. |
| Spark Retaining Wall in Furnace | Improve the combustion efficiency. |
| New Type Furnace Arch | Strength combustion, improve the adaptability of different coal types, and improve combustion efficiency |
| Header Backwater Ejection | Avoid water wall tube crack |
| Large Heating Area | Make sure excess output |
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
