Abstract

PROBLEM TO BE SOLVED: To increase the output of a turbine without increasing the inlet temperature and pressure of the turbine by mixing additional fuel restraining the fluctuations of the temperature and pressure of combustion gas after material having a high gas constant has been mixed to combustion gas to be fed to the turbine from a combustor. SOLUTION: Air 11 taken in from the outside is compressed by a compressor 1, the compressed air is led to a combustor 2, and mixed with fuel 15 fed from a fuel feed device 5 so as to be burnt. In this case, the combustor 2 is suplemented with a water feed device 4 and an additional fuel feed device 6 in order to make the gas constant of combustion gas 13 high. Water is thereby injected to combustion gas 13, and concurrently, additional fuel 16 required to make gas temperature high up to a temperature prior to water injection, is fed to the inside of the combustor 2. After that, combustion gas 13 is then expanded in the inside of a turbine 3 so as to allow the turbine 3 to produce its rotational output, and concurrently, the rotational output is then transmitted to the compressor 1 and a generator 9 respectively through respective shafts 8 and 81.
