Product Description
DZL coal fired boiler
Products features:
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.
