ASME PTC21 : 1991

Determines the performance characteristics of equipment designed to collect particulate matter from a gas steam. Specifies methods for determining the performance of the equipment with regard to the following: (a) overall mass collection efficiency of the equipment; (b) particulate matter concentration at inlet and outlet of collector; (c) efficiency of collection according to size of particle; (d) resistance to gas flow, i.e., the total pressure drop across the equipment; (e) quantity of gas passing through the equipment; and (f) power consumption of the collection equipment. Includes the rules and instructions for the particulate matter collection equipment.
