PURPOSE:To improve the thermal efficiency of a turbine cycle by previously cooling the compressed air forming a multi-phase mixture performing the heat recovery of the turbine exhaust gas with a part of the multi-phase mixture. CONSTITUTION:A part of the compressed air from an air compressor AC2 enters through a pipe 7 into a self heat exchanger SR, is cooled, is branched through an auxiliary air compressor AC3 into pipes 11-13, is mixed with the pressurized liquid phase water injected through pipes 31-33 to form a multi-phase mixture, and is introduced into the self heat exchanger SR, intermediate cooler IC, and low temperature side recuperator R3 respectively. Then, the multi-phase mixture with its heat recovered there is joined with the remainder of the compressed air and is introduced into a high temperature side recuperator R1. The compressed air forming the mlti-phase mixture is cooled by a part of the multi-phase mixture in the above-mentioned self heat exchanger SR. |
