Abstract:
A hydrogen combustion turbine plant, comprising:a compressor adapted to compress a gas to generate a compressed gas;a combustor adapted to mix the compressed gases with O.sub.2 and H.sub.2 gasses fed to the combustor, and burning and heating the mixture to form a high temperature combustion gas;a first turbine driven by the combustion gas;a channel adapted to supply a first exhaust gas from said first turbine to said compressor;a second turbine driven by the first exhaust gas partly bled from said channel;a third turbine driven by steam, said steam being provided by condensing a second exhaust gas from said second turbine and subsequently evaporating the condensate in at least one heat exchanger provided in said channel; anda cooling unit adapted to provide at least a part of a third exhaust gas from said third turbine to said first turbine to cool said first turbine.
