Abstract
A method for reducing pollution emissions from a glass melting furnace using electrostatic granular bed (EGB) technology. The granules in the EGB filter are themselves formed from an alkaline earth metal material. The granules react with sulfur compounds in the exhaust gas and form a layer of alkaline earth metal sulfates and sulfites in the granules. Simultaneously alkali metal-containing particles are deposited on the granules. The accumulated layers of pollutants are easily removed by mechanical agitation.
