Abstract
A combined cycle power plant having a steam generator and a gas turbine which makes use of a high temperature liquid couplant, or heat exchange arrangement, and a low temperature liquid couplant, or heat exchange arrangement, for maximizing use of the heat available in the power plant. The high temperature liquid couplant extracts heat from the gases leaving a coal gasifier, and is used in (1) a high temperature air heater for the gasifier, and (2) a high temperature fuel preheater of a steam generator. The low temperature liquid couplant extracts heat from the exhaust gases of the steam generator, and is used as (1) preheat for the high temperature liquid couplant, (2) low temperature air preheater for the gasifier, (3) a booster fan inlet heater, and (4) a low temperature fuel preheater for the steam generator.
