1.ISO9001/ASME
2.High Mechanization
3.National Designed A-class Boiler Manufact
4.Safe and Reliable Quality
5.Lower fuel

1.Product features:

(1). The boiler shall employ single return screwed pipe, arched tube plate, and aerofoil flue, which shall make quasisteel

resistance of the shell to change into quasi-elastomer, avoiding tube plate crack due to high temperature.

(2). The rational design of cycle scrap, shall prevent the bottom of the shell from being heated and swelling.Water

circulation reliabilities shall be improved by installing supply water injectors, avoiding the ash deposition of waterwall

tube. So the reliabile combustion equipment shall ensure the normal operation of the boiler.

(3). The optimization of the boiler type shall decrease the size of the boiler body, reducing the cost of the boiler

house 30 per cent.

(4). Because of excellent combustion efficiency, automatic coal supply, and automatic slag-removal, the labor

intensity of the stoker shall be reduced.
