ABSTRACT:
A combination gas-turbine and steam-turbine process and a power plant that utilizes the process. A waste-heat recovery system with a steam-circulation system is downstream and a pressurized furnace with a combustion chamber is upstream of a gas turbine. Flue surfaces that heat air are accommodated in the furnace. A pressurized gasifier parallels the furnace. Flue gas from the furnace, preheated combustion air, and combustion gas from the gasifier are forwarded to the combustion chamber. The heat of combustion liberated in the furnace by heating the flue gas to beyond its combustion temperature is transmitted exclusively to the combustion air being forwarded to the combustion chamber.
