Abstract
A power generating system includes a condensing steam turbine fed with steam from a boiler, wherein the air supply for the boiler combustion process is preheated by means of a heat pump system comprising at least one heat pump 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.
Claims19
A power generating system comprising:
- a condensing steam turbine fed with steam from a boiler, wherein an air supply to the boiler for a boiler combustion process in the boiler is preheated before entry to the boiler by means of a heat pump system comprising at least one variable drive heat pump;
- wherein the condensing steam turbine is coupleable to an electrical generator for generating electricity, a transformer is connected to the electrical generator for supply of electricity to a grid, and
- wherein energy provided from at least one of cooling the electrical generator and cooling the transformer is used to pre-heat condensate returning from the condensing steam turbine, by direct heat exchange or via the heat pump system.
A method for generating power, the method comprising:
- operating a power generating system comprising a condensing steam turbine fed with steam from a boiler, wherein an air supply to the boiler for a boiler combustion process in the boiler is preheated before entry to the boiler by means of a heat pump system comprising at least one variable drive heat pump;
- and
- wherein energy provided from at least one of cooling an electrical generator and cooling a transformer is used to pre-heat condensate returning from the condensing steam turbine, by direct heat exchange or via the heat pump.
