    Abstract: A power plant comprises supplies of hydrogen fuel, oxygen fuel and water, a boiler comprising a burner for combusting hydrogen and oxygen to produce heat, combustion products and low/intermediate-pressure steam and a first heat exchanger configured to heat water to generate high-pressure steam, and a steam turbine comprising a first turbine configured to be driven only with the high-pressure steam to provide input to a first electrical generator and a second turbine configured to be driven by low/intermediate-pressure steam from the boiler. A method of operating a steam plant comprises combusting hydrogen fuel in a boiler to produce combustion products and LP/IP steam, turning a turbine with the combustion products, condensing water from the combustion products in a condenser, heating water from the condenser in a heat exchanger within the boiler to produce HP steam and turning a turbine with the steam from the first heat exchanger.

    Abstract: The invention relates to a steam generation plant, comprising a steam generator (1) with a combustion chamber (8), an evaporator, a superheater (9), an intermediate superheater (12), a condenser (14), a feed water preheater (16, 19, 19′) regeneratively heated by steam, a steam turbine set (2) with a high-pressure section (4), a medium pressure section (5) and a low-pressure section (6), a flue gas line (22), connected to the combustion chamber (8), an air supply line (21), for the supply of combustion air to the burner in the combustion chamber (8) and an air preheater (3) with flue gas and combustion air passing therethrough. An air line (23) branches off from the air supply line (21) downstream of the air preheater (3) in said steam generation plant and supplies an air-fractionation unit (25). Air coolers (34, 35) are arranged in the air line (23) through which the condensate or feed water from the condensate/feed water circuit from the steam generator (1) flows. The oxygen output from the air fractionation unit (25) is connected to the burner of the combustion chamber (8) by means of an oxygen line (26).
