ABSTRACT:
A gas turbine driven powerplant having one or more compressors for producing a down stream air flow, a heat exchanger positioned down stream of the compressors followed by a side stream flow coolant line, a regenerator positioned down stream of the heat exchanger and side stream coolant line, a combustor positioned down stream of the regenerator, one or more turbines positioned down stream of the combustor and mechanically coupled to the compressors, and a power turbine positioned down stream of the turbines. Combustible effluent flows through the heat exchanger and to the combustor, and air discharged from the compressors flows through the heat exchanger and to the coolant line and regenerator. Heat is transferred from the compressor discharge air to the combustible effluent, thereby producing cooling air and heating the combustible effluent. The heat exchanger can be a heat exchanger or a methane/steam reformer which produces a hydrogen-rich, low NO.sub.x, steam diluted combustible effluent. In further embodiments, a small portion of the cool air is combined with the recuperation water in a heat recovery unit to allow vaporization of the water throughout the initial portion of the heat exchange path and form a two phased feed of water and air to the combustor. Additionally, in all embodiments a portion of the cooled compressed air can be processed by a compressor/expander for providing coolant to the turbines, compressors, and auxiliary equipment.
