Abstract
Embodiments of the present invention may provide to a gas turbine a fuel gas saturated with water heated by a fuel moisturizer, which receives heat form a flash tank. A heat source for the flash tank may originate at a heat recovery steam generator. The increased mass flow associated with the saturated fuel gas may result in increased power output from the associated power plant. The fuel gas saturation is followed by superheating the fuel, preferably with bottom cycle heat sources, resulting in a larger thermal efficiency gain.
