Air Pollution Cocntrol Technology Fact Sheet
Air flow capacity is a function of the resistance, or pressure drop across the filter and particle loading. As the dust cake forms on the filter, the resistance increases, therefore, the air flow rate decreases. Since the filter is not cleaned, t he air flow rate continues to decrease as the system operates. After the pressure drop across the ...
