Abstract:
A Multi-stage steam-power/working process for the generation of electric energy in a cycle by using an additional gaseous energy carrier for increasing pressure, temperature and mass of a working fluid in the power/working process and for recirculation of the working fluid in the power/working process, the process comprising the following steps:continuously using steam as said working fluid, performing the cycle in a closed multi stage gas-turbine plant, storing the working fluid as a condensate before start-up and after shutdown between a prime mover and a driven machine in a working-fluid storage vessel, converting stored energy of the working fluid and of the additional gaseous energy carrier into mechanical energy using said closed gas-turbine plant, utilizing an oxyhydrogen gas reaction to produce a conversion product and using said conversion product as an additional vaporous working fluid, combusting hydrogen and oxygen and using additional vaporous working fluid resulting from combusting said hydrogen and oxygen for increasing the pressure, temperature and mass of the working fluid directly at a blading stage of the closed multi-stage gas turbine plant, feeding steam as the working fluid together with the conversion product from the oxyhydrogen gas reaction to a compression stage of the cycle, and using thermal energy of expanded gas-turbine exhaust steam to pre-superheat the the working fluid after being compressed.
