ABSTRACT:
A method and apparatus for improving the overall operating efficiency of a gas turbine system by purifying relatively hot turbine exhaust gas to remove environmentally harmful components therefrom, by converting a portion of the thermal energy of the exhaust gas to mechanical work and by reclaiming a portion of the thermal energy of the exhaust gas by transferring it to other fluids. Purification to remove harmful components is advantageously accomplished using regenerators. Conversion of thermal energy to mechanical work is usefully accomplished in a primary turbine motivated by hot combustion gas and in a helper turbine motivated by a relatively hot heat exchange fluid which has derived its thermal energy by exchange with heated solids in thermodynamically efficient regenerators.
