    摘要: A process for generating power from the expansion of steam in a steam turbine system. The steam is generated by at least partially vaporizing pre-heated water by heat exchange against a first fuel gas that is generated exothermically. The at least partially vaporized water is then heated to produce the steam by heat exchange against expanded combustion product gas that is generated by the combustion of a second fuel gas in the presence of compressed oxygen-containing gas and the subsequent expansion of the combustion product gas. The steam is then expanded in a steam turbine system having more than one pressure stage to produce power and an expanded steam stream.

    摘要: A superheater in a power plant that superheats steam to operation conditions exceeding an operating limit of an associated steam-producing boiler. The superheater combusts oxygen and fuel with cooled recycled combustion gas to produce a CO2-rich combustion product gas stream at a fixed temperature. The combustion gas is used as the heat transfer fluid in the superheater's heat exchanger. The CO2-rich flue gas stream allows for efficient capture of substantially pure CO2. The superheater may be retrofitted to an existing power plant as a separate component, external to the boiler. The plant may thus have its electrical power output increased, while its overall CO2 emissions per nit of generated power is decreased, even when inexpensive, readily-available fossil fuels are used as the primary fuel for filing the boiler and/or the superheater.
