Abstract
A power generation system that comprises a first power generator; a first turbine operable to drive the first power generator; a vaporizer operable to vaporize a working fluid, wherein the vaporized working fluid turns the first turbine; and a condenser operable to condense the vaporized working fluid exiting the first turbine, wherein the condenser is coupled to the vaporizer such that the condensed working fluid is vaporized in the vaporizer. The power generation system also comprises a second power generator; a second turbine operable to burn a fuel to drive the second power generator; a switch to selectively operate the second turbine independently of the first turbine; and a heat exchanger coupled to the second turbine to receive flue gas from the second turbine when operated, wherein heat is transferred in the heat exchanger from the flue gas to the vaporized working fluid after the vaporized working fluid exits the vaporizer and prior to the vaporized working fluid entering the first turbine.
