Chain Grate Coal-Fired Boiler
The Chain Grate Coal-Fired 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 temperature.
The Chain Grate Coal-Fired Boiler 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 water-wall tube.So the reliablie combusion equipment shall ensure the normal operation of the boiler.
The Chain Grate Coal-Fired Boiler optimization of the boiler type shall decrease the size of the boiler body,reducing the cost of the boiler house 30 per cent.
Because of excellent combustion efficiency,automatic coal supply, and automatic slag-removal,the labor intensity of the stoker shall be reduced.
