Furnace air blower is widely used in 1~500t/h industrialand civil boilers, hot blast stoves, incinerators, drying furnaces, bakingovens, aging furnaces, annealing furnaces, bread ovens and ceramic kiln forblast combustion. Use for combustion and elimination of wet waste fumes.
The medium to be transported shall be air or othernon-flammable and explosive materials, non-corrosive to steel materials andfree of viscous substances. The blower allows the temperature of the medium tobe -20 to 80 ° C, the relative humidity 90%, and the content of dust and hardparticles contained in the dust does not exceed 150 mg/m 3 . The temperature ofthe flue gas conveyed by the induced draft fan can be as high as 250 °C, andthe smoke-eliminating and dust-removing device with the dust removal efficiencynot less than 85% should be installed in front of the fan to ensure that thegas hard particle content entering the induced draft fan does not exceed 250mg/m3.
The power of the induced draft fan motor refers to thelong-term stable working power of the gas delivered by the fan at a selectedflow rate and pressure of 200 ° C. If the temperature of the conveying gas isas low as 200 ° C, the gate must be reduced by means of gates or the like. Theair volume of the fan or increase the power of the motor, otherwise it is easyto cause the motor or electrical costume, which even burned!
