Process and apparatus for the generation of power

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.
