A power generating system (200) includes a condensing steam turbine (210) fed with steam from a boiler (201), wherein the air supply (202) for the boiler combustion process is preheated by means of a heat pump system (254) comprising at least one heat pump (258) with at least one compressor, before entry to the boiler. A method for generating power using the power generating system is also described. A method and apparatus for extracting heat from the gases of a combustion process are also described. |
