In 1978, Lone Star Industries (LSI) received the necessary environmental permits to construct a portland cement plant at Davenport, California of 750,000 tons annual capacity. This plant was a replacement for a smaller plant which utilized three Lepol or grate kilns of 1941 vintage. A cement plant has been continuously operated at the site since 1906. The new plant was furnished with state-of-the-art equipment which featured a roller mill for raw material preparation and a four stage preheater, precalciner pyroprocessing (kiln) system. The plant came on stream in 1981. Although a few other precalciner kiln systems had been operated in the world at that point in time, none was coal fired. Because of economics and a commitment by the domestic portland cement industry to the U.S. government to use coal for fuel in all possible plants, the Davenport plant was designed for coal firing in both the kiln and precalciner. It is well known that a portland cement kiln system has the ability to absorb considerable quantities of the sulfur dioxide which results from the combustion of a fuel.
