Combined cycle power plant

A combined cycle power plant (10) including a gas turbine (12), a steam turbine (18) and a heat recovery generator (24), for thermally connecting the gas turbine (12) and the steam turbine (18). The heat recovery steam generator (24) has a duct (28) for receiving hot exhaust gas (32) from the gas turbine (12). The heat recovery steam generator (24) is also associated with a heating system (34) for receiving feed water (36) for heating to steam. A heat pipe (30) having a first end (29) disposed within the duct (28) operates to remove heat there from. A second end (31) of the heat pipe (30) disposed within the heating system (34) operates to transfer heat to the feed water (36).
