Abstract
The gas turbine system (GT) includes a combustor (2) having a fuel injection nozzle assembly (4) for jetting hydrogen gas (H) and pure water (W), a reservoir (12) for pooling the pure water (W) to be supplied to the combustor (2), a gas compressing device (10) for boosting the hydrogen gas (H) to be supplied to the combustor (2), a fuel supply passage (6) for guiding the boosted hydrogen gas (H) towards the combustor (2), and a pressurizing passage (16) communicating between the reservoir (12) and the fuel supply passage (6) for pressurizing the pure water (W) by means of the boosted hydrogen gas (H).
Claims5
A gas turbine system which comprises:
- a combustor, haying a fuel injection nozzle assembly to inject a gas fuel and an injection water;
- a reservoir to pool the injection water to be supplied to the combustor;
- a fuel boosting unit to increase the pressure of the gas fuel to be supplied to the combustor;
- a fuel supply passage to supply the gas fuel boosted by the fuel boosting unit into the combustor;
- a pressurizing passage communicating with the reservoir and the fuel supply passage to increase the pressure of the injection water by the aid of the boosted gas fuel;
- and
- an injection water introducing passage to connect the combustor with the reservoir, the injection water introducing passage supplying the injection water to the combustor,
- wherein the gas fuel and the injection water are separately supplied to the fuel injection nozzle assembly of the combustor.
