G4-68, Y4-68 centrifugal ventilation and induced draft fans are suitable for supporting ventilation and draft fans of steam boilers under 230t / h in thermal power plants. When there are no other special requirements, G4-68 can also be used for mine ventilation and general ventilation.
The medium conveyed by the ventilator is air, and the maximum temperature shall not exceed 80 ℃; the medium conveyed by the induced draft fan is smoke, and the maximum temperature shall not exceed 250 ℃. Before the induced draft fan, a dust removal device with a dust removal efficiency of not less than 85% must be installed to reduce the dust content of the flue gas entering the fan to increase the service life of the fan.
Both the ventilator and the induced draft fan are made into a single suction, each with No. 8-16 and a total of 7 machine numbers.
