A method for improving the overall thermal efficiency of a coal power generation plant by transferring heat from a raw synthesis gas stream (101) to solid fuel (107) used as the primary feed to the gasifier (112), comprising the steps of initially cooling the syngas exhaust (101) by transferring heat to a makeup conveyance gas feed (104) to the dry feed preparation system, feeding a solid fuel component and a portion of the makeup gas stream into a grinding mechanism (106) for the solid feedstock, forming a two-phase solids/gas stream (108) comprising ground feedstock particulates and makeup gas, heating and drying the ground solid feedstock particulates to remove water, separating and removing water vapor formed in the heating and drying step, and feeding the heated and dried solids/gas stream to the gasifier (106).
