Abstract
A system incorporating an agglomerator is provided for removing fine particulates from a gas stream. The agglomerator (100) is coupled to a flue (12) for agglomerating fines (30) entrained in a gas stream, the agglomerates (40) reentrained into the gas stream are carried by ductwork (14) to an existing particulate removal system (20). Agglomerator (100) includes at least two screen electrodes (102, 104) for charging the particulates (30) and temporarily collecting the charged particles on the collection electrode screen (104). The charging electrode (102) is provided with a plurality of spaced pointed electrode elements (108), the spacing therebetween being proportional to a spacing between the two screen electrodes (102, 104). The screen electrodes (102, 104) have a grid spacing sufficiently large to insure reentrainment of the agglomerates (40) back into the bulk gas stream for separation by the existing particulate removal system (20).
