Abstract:
A gas turbine, comprising:a compressor for compressing and discharging gas supplied thereto;a combustor in which fuel is combusted with the gas discharged from said compressor;a turbine driven by the combusted gas of said combustor;a liquid droplet injection device for injecting liquid droplets into gas to be supplied into said compressor to make the temperature of the gas to be introduced into said compressor lower than the temperature of air on the upstream side of said liquid droplet injection device and the temperature of ambient air so that the injected liquid droplets introduced into said compressor together with the gas may be evaporated while flowing through said compressor; andwater recovery means disposed in a path of the exhaust gas for recovering water included in exhaust gas coming out from said turbine, and means for supplying the recovered water to said liquid droplet injection device; andwherein said water recovery means is a heat exchanger which employs liquified natural gas as coolant.
