Abstract: A cooling tower for reducing process gas temperature by vaporization of liquid water while maintaining a dry bottom operation. The gas discharge duct is located in the lower hopper of the tower and a preferred orientation of spray nozzles insures minimum condensation of the atomized water spray. The water supply is regulated by a cascade control system employing both proportional and derivative modes of control during steady state operation and only proportional control during start-up operation.

Abstract: A reverse pulse baghouse equipped with a self-contained service chamber having ventilation control in which ambient cooling is induced by the exhaust fan of the baghouse. Within the dirty-air plenum, the bags are of progressively greater length toward the center of the baghouse in order to minimize particle reentrainment and each bag is sealed against an integral collar of the tube sheet to prevent gas leakage. The hopper section, for funneling dust cake to a hinged, screw conveyor trough, is removably connected to the upper section of the baghouse and is so sized to invertably nest within the upper section during shipment.
