Title:
燃料ガスを加湿加熱する方法及び装置
Document Type and Number:
Japanese Patent JP4700786
Kind Code:
B2
Abstract:
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.
