A heat recovery system for taking out a mechanical energy from hot exhaust gas from a gas turbine comprises at least two exhaust-gas boiler each having drum of an interior pressure different from each other, a steam turbine, a generator driven by the steam turbine, steam condenser and a plurality of heat exchanger. The heat exchanger is disposed in advance of the drum of the respective exhaust-gas boiler so that a feed-water circulating through the heat recovery system is pre-heated before entering into each drum by means of a cooling water which is used to cool blades of the gas turbine and becomes very hot. |
