Integration of a gas turbine with back pressure power generation as a more efficient combined cycle plant

Magazine article, 1982

The rising cost of energy has compelled most countries to seek methods of economizing on their energy consumption, typically by the use of more energy-efficient generation processes. The combined gas and steam turbine process is one example of a step in this direction. This article reviews an investigation that has, among other things, demonstrated the feasibility of increasing the electricity produced by a back-pressure power generation plant by 30 to 40 percent for the same thermal load by combining an industrial back-pressure power generation plant with a gas turbine. In the long term this should prove highly attractive, since the electricity produced by back-pressure generation requires only half as much fuel input as electricity generated in a condensing steam power station.
