ABSTRACT:
A gas turbine set, a heat recovery boiler and a steam turbine are operated in a combined cycle to generate electric power. A gasifier generates fuel gas for the gas turbine from a reaction of fuel and compressed air supplied from the gas turbine. The booster compression process is regenerative, i.e. the air is cooled by the booster outlet air before entry to the booster and the booster outlet air is reheated by the booster inlet air prior to passage to the gasifier. Generated fuel gas is controllably heated by a heater using hot water from the heat recovery boiler. Gasifier process control is provided by a fuel ratio controller which varies the gasifier inlet fuel flow as gasifier inlet air flow varies with plant load changes.
