Abstract
Fine particles contaminating a gas stream are removed from the gas stream by moving the gas stream at a velocity of between 50 and 500 feet per second; dispersing relatively larger solid collector particles in the gas stream to cause the collector particles to capture the fine particles by interception and inertial impaction and thereby form agglomerates consisting of the collector particles having the fine particles adhered thereto; and removing the agglomerates from the gas stream. Following removal from the gas stream the agglomerates may be cleaned to separate the fine particle material from the collector particles so that the collector particles can be redispersed into the gas stream.
