Abstract: A compact but highly integrated pollution control system for use with a coal or lignite burning electrical power generating plant utilizes a stabilized continuously monitored and controlled bath through which is passed gaseous effluent containing particulate matter. In one form this may comprise a chimney of partial stainless steel construction for carrying smoke from the furnace of the plant into a body of water contained within an enclosed concrete tank where the water chemically interacts with and precipitates solids from the smoke. Within the tank a dynamic system is established which is held stable both mechanically and chemically during continuous operation. A stainless steel grill mounted just below the surface of the water breaks up air bubbles to entrap solid particles and enhance formation of a sediment.
