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.

Claim (Index 10):
The method according to  claim 1 ,\n wherein operating the second power system comprises circulating a working fluid through a heat engine, such as a Rankine cycle, to generate the secondary power, the heat engine comprising a heat source heat exchanger and a heat sink heat exchanger, wherein the method comprises\n passing the waste heat recovery fluid through the heat source heat exchanger, \n passing the working fluid through the heat source heat exchanger to obtain a heated working fluid by receiving heat from the waste heat recovery fluid.
