A pollution abatement system utilizing an afterburner and a downstream smoke-conditioning assembly including a chemical reaction filter device having a drum containing substantial quantities of loose furnace slag or limestone, the surface of which is continuously maintained reactive by the abrading action produced as the drum is continuously rotated. Furnace smoke discharged from the afterburner is injected with steam to provide sufficient quantities of water to chemically react the SO2 component in the furnace smoke with the limestone. The material abraded from the limestone passes from the drum through a series of holes formed in the peripheral surface thereof which are maintained open by contact with a series of spaced spoked wheels.
