ンプラント。1) A gas turbine device comprising a compressor, a hydrogen-oxygen combustor and a gas turbine, a first heat exchanger for recovering heat from the exhaust gas of the gas turbine, and a gas leaving the first heat exchanger. A second heat exchanger that further recovers heat from a portion of the turbine exhaust, a pipe line that returns the gas turbine exhaust that has exited the second heat exchanger to the inlet of the compressor, and the first heat exchanger. Driven by the second turbine driven by the remaining part of the gas turbine exhaust that has exited and the steam obtained by sequentially heating the condensate of the second turbine by the second and first heat exchangers, The exhaust gas is returned to the hydrogen-oxygen combustor. In a hydrogen-oxygen combustion turbine plant including a third turbine, the compressor and the gas turbine are each divided into a plurality of parts, and the third compressor is provided between the divided compressors. Two turbines A hydrogen-oxygen combustion turbine plant, characterized in that a water injection device using the condensate as a water source is provided, and the rotation axes of the divided gas turbines are different from each other.

【００１２】上記解決手段１）においては、圧力比が大
きい場合、圧縮機は分割型、ガスタービンは多軸（分割

最適に選択できるので、効率の向上は勿論のこと、圧縮
機のサージングやタービンの軸振動の回避、羽根車周速
と蒸気流れ速度に起因する性能低下（衝撃波の発生）の
抑制といった課題を解決し易くなる。In the solution means 1), when the pressure ratio is large, the number of rotations can be optimally selected by making the compressor a split type and the gas turbine multi-axis (divided and the rotation axis is different). In addition to improving efficiency, it is easy to solve problems such as surging of the compressor, avoiding shaft vibration of the turbine, and suppressing performance degradation (generation of shock waves) due to impeller peripheral speed and steam flow speed.
【００１３】解決手段１）ではまた、分割された圧縮機

度を低下させて、構造設計を容易にすることができる。
そしてその水源としては第２のタービンの復水を用いる
ので、ロスを最小にとどめることができ、別途水源を準
備する手間やコストを省略できる。In the solution means 1), since the water injection device is provided between the divided compressors, the steam heated by the compression is effectively cooled and the inflow temperature to the next-stage compressor is increased. Can be reduced to facilitate structural design.
Since the condensate of the second turbine is used as the water source, loss can be minimized, and the labor and cost of separately preparing a water source can be omitted.

ことができる。そして第２，第３のタービンからの蒸気

ら、効率上のメリットは大きい。As the cooling steam for the gas turbine, the extraction steam of the second turbine is used in the solving means 2) and the exhaust gas of the third turbine is used in the solving means 3). Therefore, the temperature and the pressure are fine. Cooling steam can be supplied. Since the steam from the second and third turbines is steam that has already finished work in those turbines, the efficiency advantage is great.

いので、効率が向上する。Further, if the cooling steam is discharged to the main stream, a large loss occurs, but in the solution means 4), the gas turbine and / or the combustor is cooled by the steam extracted from the exhaust of the third turbine, and then recovered. However, the efficiency is improved because it is not discharged into the mainstream.
