Abstract:
Apparatus for generating power comprising:a) a gas turbine unit having a compressor for compressing ambient air and producing compressed air, a combustion chamber to which said compressed air is supplied, a source of relatively high grade fuel for burning in said combustion chamber and producing combustion gases, a gas turbine connected to a load and to said compressor for expanding said combustion gases and driving said load, and for producing exhaust gases;b) an energy converter responsive to said exhaust gases for converting heat therein to power, said energy converter including a working fluid vaporizer containing a working fluid that is vaporized by said exhaust gases, a turbine responsive to vaporized working fluid produced by said working fluid vaporizer for producing power and expanded working fluid, a working fluid condenser responsive to said expanded working fluid for condensing the latter to working fluid condensate, and means for returning said working fluid to said working fluid vaporizer;c) means for heating heat transfer fluid that flows in a closed loop; andd) a preheater interposed between said working fluid condenser and said working fluid vaporizer, said preheater transferring heat from said heat transfer fluid to working fluid utilized by said energy converter.
