Control of Heavy Metal Emissions from Waste Incinerators

Abstract

Incineration of municipal wastes is being increasingly used as a means of managing waste disposal problems due to limited avail-ability of landfill space. Emissions from waste incineration plants must be controlled to the lowest possible concentration to minimize health impact. An emission control system consisting of a semi-dry scrubber in conjunction with a dry venturi and a fabric filter has been employed at various plants. Operating data from this system indicates extremely low emissions including heavy metals, particulates, sulfur dioxide and hydrogen chloride.
