4 tons coal fired/biomass/wood fired boiler

DZL seires 4 tons coal fired/biomass/wood fired 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.

Main Characteristics of 4 tons coal fired/biomass/wood fired boiler

1.The overall layout is compact, covers a small area. Only single storey layout is needed for the boiler

room, low cost on infrastructure construction, convenient for transportation, and short installation

period.   

2.Using spirally corrugated tubes, strengthen the disturbance of flue gas, high heat transfer efficiency.

3.Reasonable design, safe and reliable operation, flat fire bed, and high thermal efficiency.

4.Complete auxiliaries, mechanized coaling and slag tapping, convenient operation.

5.Use chain grate, low coal leakage, good ventilation, wide adaptability of different coals.

6.The boiler shell use aluminium silicate board for heat preservation, low heat loss.

7.Equipped PLC full automatic intelligent control system, operate automatically.

8.Full automatic interlock protection program, has the protection function of water shortage, over

pressure, over temperature, gas leakage, flame out, and electric leakage, etc.

9.By equipping with economizer, make full use of flue gas heat, increase the thermal efficiency.
