ABSTRACT:
Unclean fuel, such as coal is reduced to particle size passing 200 mesh in an attrition mill. Pyrite and ash removal is performed in conjunction with the attrition milling. The resulting fine particles are combusted in the turbine exhaust gas and the products of combustion indirectly heat the turbine operating gas. Control is provided by bypass around the heat exchanger and/or auxiliary clean fuel combustion.
