Model: 4-73 Series
4-73 Series Centrifugal Fan With the for Boilers and Mineral Industries
In normal operations, the medium conveyed by the ventilation fan is air, with a maximum temperature not exceeding 80 ℃. The medium conveyed by the induced draft fan is flue gas, with a maximum temperature not exceeding 250 ℃. A dust removal device must be installed in front of the induced draft fan. According to the general use of power plants, the content of dust and hard particles should not exceed 150mg/m3. (G4-73 design temperature is 20 ℃, Y4-73 design temperature is 200 ℃).
