1. Use

  gy4-68 type boiler centrifugal pass, fan is suitable for the thermal power plant in the 230t/h steam boiler under the Pass, Fan series.In the absence of other special requirements, the g4-68 type can also be used for mine ventilation and general ventilation.

  The medium to be transported by the fan is air, the maximum temperature shall not exceed 80 ℃, and the medium to be transported by the fan shall be flue gas, and the maximum temperature must not exceed 250 ℃.
Before the fan, the dust removal device with no less than 85% dust removal efficiency should be added to reduce the dust content of the flue gas entering the fan, so as to improve the service life of the fan.
