ABSTRACT:
A method for producing power from coal in a combined cycle apparatus 10 is disclosed. A partial gasifier 22 is used to convert the coal into combustible fluids and combustible char. An auxiliary combustor 20 is employed to burn the char and provide heat to the steam turbine engine cycle. The combustible fluids are burned directly in the gas turbine engine cycle. The efficiency of the cycle is improved by adding coal to the gasifier to improve the efficiency of the gasifier and the steam turbine engine cycle.
