Point-Source PM Controls by Emerging and Conventional Technologies
Advantages Disadvantages Cannot control a high-temperature (>550º F) Lower pressure drop than venturi for fine PM stream without a precooler removal (i.e.,2–6 in. H 2O compared with Cannot control highly humid stream > 40 in. H 2 O for Venturi) Special fabric requirements Simple to operate Mechanical collectors required for large (>20 Can collect electrically resistive PM µm)
