Abstract

Solid carbonaceous fuel, such as bituminous coal, is copulverized with a basic metal reactant to provide a microground prepared fuel predominantly in minus 325 mesh particles of high specific surface area. The prepared fuel is fed directly to a burner and effects ninety-five percent (95%) or better removal of the sulfur from the fuel prior to emission.
