It is very important to control the speed of flue gas passing through the filter material (called filtration speed) during the operation of bag filter. The filtration speed is generally 0.5-2m/min, and the efficiency for particles larger than 0.1μm can reach more than 99%, and the equipment resistance loss is about 980-I470Pa.
