摘要： 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.

摘要： A supercritical steam combined cycle system including a gas turbine; a supercritical steam turbine system including a supercritical section, a high pressure section, an intermediate pressure section and at least one low pressure section; and a supercritical steam heat recovery steam generator (HRSG) for receiving exhaust gas from the gas turbine for heating fluid from the steam turbine system. The HRSG includes a supercritical evaporator arranged to supply steam to a superheater between the supercritical evaporator and the inlet of the HRSG and a reheater receiving cold reheat steam from and returning reheated steam to the steam turbine system. The reheater includes a first section disposed downstream of and a second section disposed upstream of the supercritical evaporator along the exhaust gas flow path. Cool reheat steam from the steam turbine system is received by the first reheater section and steam leaving the first reheater section is supplied to the second reheater section upstream of the supercritical evaporator.

摘要： An embodiment of the present invention may take the form of a system and method that may use at least one solar heating system to heat the fuel consumed by a turbomachine. An embodiment of the present invention may incorporate concentrated solar power (CSP). Generally, CSP systems incorporate a plurality of lenses, mirrors, or combinations thereof and a tracking system to focus a large area of sunlight forming a small concentrated beam of light. The concentrated light may then be used as a heat source. In an embodiment of the present invention, the heat source may be used to partially or completely heat the fuel consumed by a turbomachine. CSP systems may take the form of a solar trough system, a parabolic dish system, a solar power tower system, or the like.

摘要： In a combined cycle power system having a gas turbine and one or more bottoming cycle expansion turbines for driving one or more generators, compressor inlet air to the gas turbine is cooled. An extraction is taken from the distillation condensation sub-system of the Kalina cycle and throttled to a lower pressure, with a corresponding temperature drop for supply to a low pressure evaporator in heat exchange relation with ambient air flowing to the compressor inlet to cool the ambient air. The partially evaporated multi-component mixture exiting the low pressure evaporator is returned to the spent vapor stream from the low pressure expansion turbine for combination therewith and condensation. Consequently, compressor inlet air inlet to the gas turbine is cooled, thereby increasing mass flow and turbine output.
