Abstract: The invention provides a method of generating power using a combined cycle, comprising operating a first power system in which fuel is burned to generate primary power and a flue gas stream at a flue gas temperature greater than 450° C., and operating a second power system to generate secondary power from the heat comprised by the flue gas stream, the second power system comprising a waste heat recovery heat exchanger. The method further comprises passing the flue gas stream through the waste heat recovery heat exchanger, passing a pressurized waste heat recovery fluid through the waste heat recovery heat exchanger to receive heat from the flue gas stream thereby obtaining a pressurized vaporous waste heat recovery fluid having a temperature in the range of 350° C.-500° C. The waste heat recovery fluid comprises more than 75 mol % of fluorinated ketones.
