摘要:
A power generating method that includes the steps of burning a reformed fuel in the presence of air in a combustor (118) of a gas turbine (138) to generate a hot exhaust gas is disclosed. The hot exhaust gas is then passed through a turbine section of the gas turbine to generate power and, thereafter, the hot exhaust gas (140) is passed through a heat recovery system (112) where the hot exhaust gas is successively cooled as it passes through a series of heat exchangers. Heat exchangers comprising the heat recovery system include combustion air pre-heater(s) (114); a thermochemical recuperator (or reformer) (128), wherein hot exhaust gas provides the endothermic heat of reaction necessary to reform a raw fuel/steam mixture to the combustible, reformed fuel that is eventually burned in the combustor; and one or more water/steam heater (142) which supply steam to a low-pressure, condensing steam turbine (152) of a bottoming Rankine cycle to generate additional power.
