Product Description

Coal fired single drum threaded fire pipe steam boiler

1.The boiler shall employ single return screwed pipe,arched tube plate,and aerofoil flue,which shall make quasi-steel resistance of the shell to change into quasi-steel,avoiding tube plate crack due to high temp.

2.The rational design of cycle scrap,shall prevent the bottom of the shell from being heated & swelling.Water circulation reliabilities shall be improved by installing supply water injectors,avoiding the ash deposition of water-wall tube.So the reliablie combusion equipment shall ensure the normal operation of the boiler

3.The optimization of boiler type shall decrease the size of boiler body,reducing the cost of boiler house 30%

4.Because of excellent combustion efficiency,automatic coal supply,automatic slag-removal,the labor intensity of the stoker shall be reduced

SZL coal fired steam boiler

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.
