SZL Chain Grate Coal Fired Steam Boilers
1.The
boiler shall adopt double drum,monolayer arrangement,compact
structure,as well as large heating surfaces which are more 10% than
those of same kinds of products,featuring the following advantages such
as sufficient output,safe and reliable operation,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.
