An externally fired gas turbine system according to the present invention has a compressor for compressing ambient air and producing compressed air, an air heat exchanger for heating the compressed air to produce heated compressed air, a turbine for expanding the heated compressed air to produce heat depleted expanded air, and a generator connected to the turbine for generating electricity. According to the present invention, the system also includes combustible products producing apparatus for processing fuel to produce combustible products that include combustible gases and an external combustion chamber for burning the combustible products and transferring heat to the air heat exchanger and producing heat depleted combustion products. The system also includes a closed Rankine cycle steam power plant having a water heat exchanger for vaporizing water and producing steam using heat contained in the heat depleted combustion products. The power plant further includes a steam turbine for expanding the steam producing power and expanded steam, and a steam condenser for condensing the expanded steam producing condensate that is returned to the water heat exchanger.

1. Apparatus for producing power comprising:a) an indirect contact heat exchanger responsive to heat coming from combustion products for heating a substance and for producing products comprising a heated substance and cooled combustion products; b) means utilizing heat associated with the heated substance produced by said indirect heat exchanger for converting heat to power, said means comprising an energy converter containing a working fluid and having a working fluid vaporizer containing said working fluid that is vaporized by heat associated with the heated substance, a turbine responsive to vaporized working fluid produced by said working fluid vaporizer that, produces power and expanded working fluid, and a working fluid condenser responsive to said expanded working fluid that condenses the latter to working fluid condensate whereby said working fluid condensate is returned to said working fluid vaporizer; c) means for heating heat transfer fluid that flows in a closed loop; and d) a preheater for transferring heat from said heat transfer fluid to working fluid contained in said energy converter by transferring the heat to working fluid condensate for preheating said working fluid condensate before it is supplied to said working fluid vaporizer.
