Hamilton, S; Horgan, J J

A combined powerplant 10 employing a gas turbine engine cycle 12 and a steam turbine engine cycle 14 is disclosed. The powerplant includes a partial gasifier 22 and an auxiliary combustor 20. The powerplant utilizes the heating value of coal in a two-stage combustion process by burning the gases derived from the coal within the gas turbine engine and by burning the char derived from the coal externally of the engine in the auxiliary combustor. Heat is transferred from the auxiliary combustor to the respective working mediums of both engines.
