ABSTRACT:
A combined cycle power generating system includes high, intermediate and low pressure vapor turbines for driving a generator or other load by expanding a multi-component fluid mixture through the turbines. A gas turbine is drivingly connected to the generator or other load. The expanded multi-component mixture exhausted from the intermediate pressure turbine flows in heat exchange relation with the fuel inlet to the combustor for the gas turbine whereby the gas turbine fuel is preheated to reduce fuel consumption of the gas turbine and increase combined cycle efficiency.
