PURPOSE:To enable gas fuel to be preheated while eliminate the necessity for an external heat source for preheating the gas fuel, by introducing an outlet side pipe of a water injection pump into an exhaust duct and heating delivery water so as to utilize thermal energy in exhaust gas. CONSTITUTION:Air is inducted from a suction duct 7, and the air, after it is compressed by a compressor 2, is forced to be fed to a combustor 8. While fuel is stored in a liquid state in a tank 13, and the fuel, after its pressure is increased by a booster pump 12, is vaporized in a carburetor 11 being allowed to flow into the combustor 8 via a pressure control valve 10 and a flow control valve 9. And a turbine 4, in which high temperature gas from the combustor 8 is used as rotating energy, both rotates a generator 5 and discharges the gas from an exhaust duct 6. In the above system, water from a water tank 15, increasing the pressure by a water injection pump 16, is allowed to flow passing in the exhaust duct 6. And the system, introducing into a gas fuel preheater 14 the water increasing its temperature, allows gas fuel to flow into the combustor 8 by increasing a temperature of the gas fuel. |
