The invention provides a gas turbine, a combined plant and a compressor by which both of augmentation of the power output and augmentation of the thermal efficiency can be realized by injecting liquid droplets into inlet air introduced into an entrance of a compressor with a single equipment which is suitable for practical use. The gas turbine includes a compressor for taking in and compressing gas, a combustor in which fuel is combusted with the gas discharged from the compressor, and a turbine driven by the combusted gas of the combustor. The gas turbine further includes a liquid droplet injection device provided on the upstream side of the compressor for injecting liquid droplets into inlet air to be supplied into the entrance of the compressor to lower the temperature of the inlet air to be introduced into the compressor so that the injected liquid droplets may be evaporated while flowing down in the compressor.

FIG. 2 is a similar view showing another embodiment of the present invention;
FIG. 3 is a similar view showing a further embodiment of the present invention;
A first embodiment of the present invention will be described with reference to FIG. 1.
A gas turbine of the embodiment of the present invention includes, as shown in FIG. 1, a compressor 1 for compressing and discharging gas, a combustor 5 to which the gas compressed by the compressor 1 is supplied, a turbine 2 driven by the combustion gas by the combustor 5, a generator 3 connected to a shaft of the turbine 2, and a electric power grid 4 for transmitting power generated by the generator 3. Exhaust gas 7 from the gas turbine is discharged into the atmospheric air through a stack 8.
In the following embodiment, it is assumed that the gas supplied to the compressor 1 is air.
