Abstract
A gas turbine power generating system comprising, in the preferred embodiment, three gas turbine engines in series-connected flow communication employing high pressure hydrogen and oxygen as the fuel. Pre-heated pressurized steam (or a steam and water mixture) is fed to the initial gas turbine combustor for combustion coolant. Steam, consisting of the products of combustion plus the vaporized coolant, is exhausted from the first turbine into the combustor of the next turbine for re-heating via the combustion therein of the high pressure hydrogen and oxygen. The exhaust steam from the intermediate turbine is in turn re-heated in the combustor of the final turbine. The final exhaust steam is then passed through a recuperative heat exchanger to pre-heat the pressurized cooling water so that, when injected into the first combustor, it is vaporized prior to entering the first turbine.
