Boiler forced fan and induced draft fan is mainly used in forced draft and induced draft fan system of the boiler. Forced,induced draft fan can be used for mine ventilation and general ventilation.

 

 

 

The conveying medium of the forced draft fan is air,the highest temperature should not be more than 80°C;while the conveying medium of the induced draft fan is flue gas,the highest temperature should not be more than 250°C.

 

 

 

Induced draft fan must be equiped with dust removal device at front,so as to reduce the flue gas dust content which flows into the fan,reduce smoke dust to fan abrasion and improve the serious life of the fan.
