Classification: CPC F  Y | IPC F

Claim 11:
12. A gas turbine comprising:
a compressor that compresses air taken from an air intake line;
a combustor that mixes and combusts the compressed air compressed by the compressor and fuel;
a turbine that obtains rotational power using combustion gas generated by the combustor;
a compressed air cooling heat exchanger that cools the compressed air to produce air for heat exchange;
an air temperature adjusting heat exchanger that exchanges heat between the compressed air and the air to be supplied to the compressor;
a heat exchange amount adjusting device that adjusts a heat exchange amount of each of the compressed air cooling heat exchanger and the air temperature adjusting heat exchanger; and
a control device that controls the heat exchange amount adjusting device, wherein
the control device controls the heat exchange amount adjusting device based on a temperature of the air to be taken into the compressor,
the air temperature adjusting heat exchanger includes a first heat exchanger which is provided in the air intake line,
the first heat exchanger of the air temperature adjusting heat exchanger exchanges heat between the air and a first medium, and the air temperature adjusting heat exchanger includes a second heat exchanger that exchanges heat between the compressed air and the first medium, and
the heat exchange amount adjusting device adjusts a heat exchange amount in the second heat exchanger.
