Y5-48 boiler centrifugal induced draft fan is to adapt to various coal burning and dust removal device 1 ~ 20t / h industrial boiler supporting design. Where the inlet conditions can be quite the performance but also to adapt can be selected. The maximum temperature should not exceed 250 ℃, induced draft fan must be installed before the efficiency of not less than 85% of the dust removal device to reduce the dust content of flue gas into the fan in order to facilitate the increased fan life. Boiler fan is a follower of fluid machinery, it relies on the input of mechanical energy, improve gas pressure side to send gas machinery. It works similar to the turbine compressor, due to the low gas flow rate, pressure changes little, generally do not need to consider changes in specific volume of gas that the gas as an incompressible fluid handling.
