6-51 series centrifugal draft fan

Fan form

　　The air volume of 6-51 series centrifugal induced draft fan is: 2752-498507㎥/h, the wind pressure is: 1706-8265Pa, the power is: 18.5kw-2000kw, the blower and the induced draft fan are made into single suction form. There are 42 specifications in total with 21 machine numbers from №8 to 31.5F. The fan transmission mode is F type (ie: double support structure), and the connection between the motor and the fan adopts an elastic coupling for direct drive. An example of the full name of the product is as follows: G6-51-1№20F right 45 degrees/135 degrees, where G and Y represent the boiler supply fan and the boiler induced draft fan respectively, 5 is the pressure coefficient of the highest efficiency point, 10 times the whole, and 51 is the ratio Speed, 1 is the first design, №20 means the impeller diameter is 2000mm.

Details description

　　The 6-51 boiler draft fan is mainly used for the draft fan system of 2t/h~670t/h steam boilers in thermal power plants, and it also meets the requirements of the performance parameters of the high pressure head of the fluidized bed furnace. This series of fans can also be used for dust removal, mine ventilation and general ventilation systems. The medium conveyed by the blower is air, and the medium conveyed by the induced draft fan is flue gas or gas containing impurity particles. When the impurity concentration is less than 200mg/m3, it can be used for more than four years. It can also be used if the impurities are large, but the service life is relatively shortened. The temperature used by the draft fan should not exceed 250°C. And has the characteristics of high efficiency and low noise, it is a centrifugal fan product series with a wide range of performance.
