ABSTRACT:
An apparatus 10 for consuming coal in powering a gas turbine engine 12 is disclosed. The apparatus includes an auxiliary combustor 16 and a partial gasifier 18. The gasifier 18 produces combustible char and combustible fluids. The combustible fluids are burned in the gas turbine engine. The combustible char is burned in the auxiliary combustor to form high temperature gases. Heat is transferred from the high temperature gases to the working medium flow path of the gas turbine engine. The exhaust from the gas turbine engine provides combustion air to the fluidized bed combustor.
