Gas turbine installation

A plate fin type recuperator for heating humid compressed air containing liquid phase water by combustion exhaust gas with a combustion exhaust gas channel and a compressed air channel partitioned from each other by a tube plate,

• wherein a pitch of fin members and a height of said fin members forming the compressed air channel are set to values sufficient to prevent the liquid phase water contained in the compressed air from bridging between adjacent two of said fin members or tube plates under action of surface tension.

A plate fin type recuperator for heating humid compressed air containing liquid phase water by combustion exhaust gas,

• wherein said recuperator comprises a first region for heating the humid compressed air containing liquid phase water and a second region for heating the humid compressed air from which the liquid phase water has evaporated in the first region, and
• a pitch of fin members disposed in the first region is set to the Laplace length.

A plate fin type recuperator for heating humid compressed air containing liquid phase water by combustion exhaust gas,

• wherein said recuperator comprises a first region for heating the humid compressed air containing liquid phase water and a second region for heating the humid compressed air from which the liquid phase water has evaporated in the first region, and
• a pitch of fin members and a height of said fin members installed in said first region are set to values sufficient to prevent the liquid phase water contained in the compressed air from bridging between adjacent two of said fin members or tube plates under action of surface tension.

A gas turbine power system comprising a compressor for compressing air, a combustor for combusting the air compressed by said compressor and fuel, a turbine driven by combustion gas produced in said combustor, a recuperator for performing heat exchange between exhaust gas exhausted from said turbine and the compressed air supplied to said combustor from said compressor, and a humidifier for supplying liquid phase water to the compressed air supplied from said compressor,

• wherein said recuperator is a plate fin type recuperator for heating humid compressed air containing liquid phase water by combustion exhaust gas, and a pitch of fin members forming a compressed air channel is set to the Laplace length.
