DHL Series Biomass Fired Boiler Introduction

The Industrial energy saving DHL series biomass fired boiler is drawn on the basis of the other biomass boilers experi-ence, through the optimization design to made it. The fuel adaptability, make it can apply to various different ty-pes of straw fuel. and it’s high combustion efficiency, especially can solve the straw fuel chlorine, sulfur content is high on the boiler heating surface effect and reduce the corrosion of equipment and wear. The smoke also reduces the pollution to the environment, and it has the characteristics of high combustion efficiency and low pollution, while the furnace is pure burning straw, do not need to add other bed material, so from the ash,slag can be directly used as fertilizer, so it’s a kind of high efficiency energy saving and environm-ental protection products.


DHL Series Biomass Fired Boiler Advantages


Safe Water Circulation

The DHL series biomass fired boiler adopts a unique water circulation structure, the drum is free from heat and the heated water flows in one direction. In the event of a power outage, the water system does not vaporize and the water circulation is safe and reliable.


Anti Seismic Structure

Corner tube boiler adopts non-framework structure, boiler proper weight is supported by membrane wall and down comer, and all membrane walls are all welded into one whole, with good anti-seismicity.


Complete Sealed Structure

  1. All around the boiler proper is made of welded membrane walls, and the steel structure is completely sealed to prevent the occurrence of air leakage.
  2. The upper part of the boiler can be divided according to the size of the railway transportation limit.
  3. The excess air coefficient after the heating surface of the boiler tail is only less than 1.2, which not only reduces the heat loss of the exhaust fumes, reduces the power consumption of the induced draft fan, but also greatly reduces the environmental pollution of the boiler house.
