Abstract

A fly ash agglomerator for improving the efficiency of the electrostatic precipitators. Contaminated gas is passed through a charger wherein suspended particles become elec­ trically charged, and thence past a plurality of parallel plates aligned with the flow direction. An AC voltage source applied to the plates subjects the charged particles to a high voltage AC field, which causes the larger-sized particles to sweep past the smaller-sized particles. The smaller particles adhere to the larger particles, thereby increasing the mean particle size. The gas stream is then passed through a collector to remove the particles from the gas stream.
