摘要： A combined cycle system includes gas and steam turbines, a saturator (201) and a fuel gas superheater (202) for supplying moisturized heated fuel gas to the gas turbine, a gas turbine exhaust heat recovery system for generating steam and heating water for the superheater and a saturator heater for a recycle water conduit (211). A constant ratio of water supplied to the fuel gas saturator to dry fuel gas supplied to the fuel gas saturator is maintained by adjusting (203) the flow of the recycle water stream. Additional properties of the moisturized fuel gas, such as temperature, moisture content, composition, and heating value, are also used to control the water recycle stream to supply consistent moisturized fuel gas to the gas turbine system.

摘要： Fuel gas is saturated with water heated with a heat recovery steam generator heat source. The heat source is preferably a water heating section (162) downstream of the lower pressure evaporator to provide better temperature matching between the hot and cold heat exchange streams in that portion of the heat recovery steam generator. The increased gas mass flow due to the addition of moisture results in increased power output from the gas and steam turbines (116,118). Fuel gas saturation is followed by superheating the fuel, preferably with bottom cycle heat sources (160), resulting in a larger thermal efficiency gain compared to current fuel heating methods. There is a gain in power output compared to no fuel heating, even when heating the fuel to above the LP steam temperature.
