ABSTRACT:
A gas turbine apparatus has an air compressor for compressing air, a combustor capable of combusting the compressed air, a turbine rotatable by a gas discharged from the combustor, and a recuperator for exchanging heat between the air supplied from the air compressor and an exhaust gas discharged from the turbine. The gas turbine apparatus includes a fuel supply system having a first fuel supply device for supplying a fuel having a large heating value to the combustor, a second fuel supply device for supplying a gas having a small heating value to the combustor, and a switching device operable to switch the first fuel supply device and the second fuel supply device based on a temperature of the air compressed by the air compressor or the exhaust gas discharged from the turbine.
