High Furnace for Burning Biomass Wood Sawdust Rated Steam and Hot Water Boiler

High Furnace for Burning Biomass Wood Sawdust Rated Steam and Hot Water Boiler

1.The boiler shall adopt double drum,monolayer arrangement,compact structure,as well as large heating surfaces which aremore 10% than those of same kinds of products,featuring the following advantages such as sufficient output,safe and reliableoperation,short construction period,low installation cost ect.
2.The design of cyclone reburning chamber in furnace resulted in the decrease of dust contained in the flue gas.At the same time,incandescent carbon black particles shall burn further,enhancing the boiler thermal efficiency,decreasing gas blackness,as a result,the gas emission concentration shall meet the requirements of grade A environmental protection area.
3.The grate shall employ the technology patent of small roller structure,boundary grate and so on,improving the operation reliability of the boiler.
4.Since the adoption of technology patent for the sealed wind chamber and bilateral grate air register,and the application of machining cone seal structure to grate adjusting air eauipment,the sensitivity of the grate shall be improved.
Boiler main body will be loaded on the 20' or 40' FR(flat rack) containers with weather cloth,boiler accessories will be packed with plywood boxes and loaded in the 20-feet or 40-feet GP(Standard) containers.

Weclome to Qingdao,we will talk more details,check our workshop and running boilers.
