Combination power generating system

Abstract

A combination power generating system includes a first power generating system, which boils water into steam to turn a first turbine for driving a first generator to generate electricity, and a second power generating system, which utilizes waste heat from the first power generating system to heat an organic solvent into organic vapor for turning a second turbine to drive a second generator to generate electricity.

1 . A combination power generating system, comprising:
 a first power generating system, said first power generating system comprising a first generator for generating electricity, a first turbine for rotating said first generator to generate electricity, a first steam boiler holding a predetermined amount of water, heater means for heating the water in said first steam boiler into steam for turning said first turbine in driving said first generator to generate electricity, and a first cooling coil means for cooling the steam passing through said first turbine into condensed water and guiding the condensed water back to the said first steam boiler; and   a second power generating system, said second power generating system comprising a second boiler holding an organic solvent and surrounding a part of said first cooling coil means for enabling said solvent to be heated into organic vapor by heat energy of steam that goes out of said first turbine into said first cooling coil, a second generator for generating electricity, a second turbine rotated by the organic vapor produced in said second boiler for rotating second generator to generate electricity, a second cooling coil means for cooling the organic vapor passing through said second turbine into condensed solvent and guiding the condensed solvent back to said second boiler, and a cooling pond for circulating a cooling water or cooling air to cool down said second cooling coil.
