Abstract
In an intake-air refrigeration system of intake-air cooling type gas turbine power equipment, heat discharged to the atmosphere heretofore is recovered for further utilization. A refrigerant vapor discharged from and evaporator (05) of the refrigeration system is compressed by a refrigerant compressor (02) to be transformed to pressurized refrigerant vapor. Heat carried by the pressurized refrigerant vapor is supplied to a heat utilization system (80) to be recovered therein.
Claims5
An intake-air cooling type gas turbine power equipment, comprising:
- a refrigeration system including an evaporator and a refrigerant compressor;
- an intake-air cooling chamber for cooling air taken in from the atmosphere by said evaporator of said refrigeration system;
- an intake air heating system that heats the cooled air to thereby obtain dry, low temperature air;
- an air compressor for compressing the dry, low temperature air to thereby produce compressed air;
- a combustor for burning a fuel supplied from an external system with the compressed air produced by said air compressor to thereby produce a combustion gas;
- a gas turbine driven rotationally under the action of said combustion gas produced by said combustor;
- and
- an electric generator operatively coupled to a rotor shaft of said gas turbine for generating electric energy, being driven through rotation of said rotor shaft;
- wherein the refrigerant vapor leaving said evaporator of said refrigeration system is compressed by said refrigerant compressor to be transformed to a pressurized refrigerant vapor, and
- wherein heat carried by said pressurized refrigerant vapor is supplied to the intake air heating system.
