Composite cycle plant

Abstract

Abstract PURPOSE: To enhance thermal efficiency of a composite cycle by combining a gap turbine cycle with a Rankine cycle which uses low boiling fluid as working fluid, via an intermediate cooler of a gas turbine compressor. CONSTITUTION: Suction air of a compressor 1 is compressed to a specified pressure while adiabatic compression and constant pressure cooling are repeated by the compressor 1 and a multi-stage intermediate cooler 2 mounted between stages. Air, which leaves the compressor 1, is guided to a combustor 4 after being preheated at a heat exchanger 3, and then guided to a turbine 5 after generating hot high pressure gas. On the other hand, low boiling point medium after given pressure by a pump 8 and heated at the intermediate cooler 2 via heat exchange with compressed air, is guided to a heat exchanger 7 and heated by gas turbine exhaust gas to become vapor. It flows into a turbine 9 and works. The low boiling point medium which has rotated the turbine 9 is cooled and liquefied in a condensor 10. COPYRIGHT: (C)1982,JPO&Japio
