ABSTRACT:
An externally fired gas turbine system according to the present invention has a compressor for compressing ambient air and producing compressed air, an air heat exchanger for heating the compressed air to produce heated compressed air, a turbine for expanding the heated compressed air to produce heat depleted expanded air, and a generator connected to the turbine for generating electricity. According to the present invention, the system also includes combustible products producing apparatus for processing fuel to produce combustible products that include combustible gases and an external combustion chamber for burning the combustible products and transferring heat to the air heat exchanger and producing heat depleted combustion products. The system also includes a closed Rankine cycle steam power plant having a water heat exchanger for vaporizing water and producing steam using heat contained in the heat depleted combustion products. The power plant further includes a steam turbine for expanding the steam producing power and expanded steam, and a steam condenser for condensing the expanded steam producing condensate that is returned to the water heat exchanger.
