Abstract
Abstract An expanded-vapor-driven device is driven by pressurized vapor from a generator, and a pressurized-liquid-driven device is driven by pressurized liquid from the same generator. The working fluid in the generator is preferably a mixture of two different fluids, one of which is more volatile than the other and which is soluble in the other. The vapor and liquid exhaust from the two devices is piped to an absorber unit where the vapor and liquid are cooled and remixed before being recycled back to the generator. The absorber is located in the air inlet path to the burner for the generator and preheats the primary and secondary air for the burner. The mixed fluid from the bottom of the absorber is pumped to a heat exchanger which is connected so as to be in a heat exchange relationship with the hot liquid that is moving from the bottom of the generator to the pressurizedliquid-driven device. This preheats the mixed fluid just before it is pumped into the generator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A power plant comprising a closed generator for a working fluid, means for heating the working fluid in said generator to vaporize the fluid and pressurize the vapor thereof, an expandedvapor-driven device having a vapor inlet port and a vapor outlet port, a pressurized-liquid-driven device having a liquid inlet port and a liquid outlet port, vapor conduit means coupling the upper portion of said generator to the vapor inlet port of said expanded-vapor-driven device to drive the same, liquid conduit means coupling the lower portion of said generator to the liquid inlet port of said pressurized-liquid-driven device to drive the same, and means including an absorber coupling the outlet ports of both of said devices to said generator, said absorber being operable to condense the vapor exhausted from said expandedvapor-driven device and combine it with the liquid from the pressurized-liquid-driven device to provide working fluid for return to said generator, said means for heating said working fluid comprising a fuel burner and said absorber being mounted in the path of the air input for said burner to preheat said air input while the latter serves as cooling air for the absorber.
Claim 2
Dependent Claim
191 words
A power plant comprising a closed generator for a working fluid, means for heating the working fluid in said generator to vaporize the fluid and pressurize the vapor thereof, an expandedvapor-driven device having a vapor inlet port and a vapor outlet port, a pressurized-liquid-driven device having a liquid inlet port and a liquid outlet port, vapor conduit means coupling the upper portion of said generator to the vapor inlet port of said expanded-vapor-driven device to drive the same, liquid conduit means coupling the lower portion of said generator to the liquid inlet port of said pressurized-liquid-driven device to drive the same, and means including an absorber coupling the outlet ports of both of said devices to said generator, said absorber being operable to condense the vapor exhausted from said expandedvapor-driven device and combine it with the liquid from the pressurized-liquid-driven device to provide working fluid for return to said generator, said means for heating said working fluid comprising a fuel burner and said absorber being mounted in the path of the air input for said burner to preheat said air input while the latter serves as cooling air for the absorber.
Claim 3
Dependent Claim
217 words
A power plant having a working fluid mix which consists of a mixture of two fluid portions, a first one of said fluid portions being more volatile than a second one of said fluid portions and being soluble in said second fluid portion, a closed generator for said working fluid, means for heating the working fluid in said generator to vaporize the first fluid portion thereof and to pressurize the vapor thereof and place the second fluid portion under pressure, a fluid-driven device having a fluid inlet port and a fluid ouTlet port, conduit means coupling a portion of said generator which has the second fluid portion of the fluid inlet port of said device to drive the device, means including an absorber for coupling the fluid outlet port of said device to said generator, means for returning the first fluid portion from the generator to the absorber, said absorber being operable to condense said first fluid portion and including means for combining the two fluid portions to form a fluid mix for return to said generator, said means for heating said working fluid comprising a burner and said absorber being mounted in the path of the air input for said burner to preheat said air input while the latter serves as cooling air for the absorber.
Claim 4
Dependent Claim
217 words
A power plant having a working fluid mix which consists of a mixture of two fluid portions, a first one of said fluid portions being more volatile than a second one of said fluid portions and being soluble in said second fluid portion, a closed generator for said working fluid, means for heating the working fluid in said generator to vaporize the first fluid portion thereof and to pressurize the vapor thereof and place the second fluid portion under pressure, a fluid-driven device having a fluid inlet port and a fluid ouTlet port, conduit means coupling a portion of said generator which has the second fluid portion of the fluid inlet port of said device to drive the device, means including an absorber for coupling the fluid outlet port of said device to said generator, means for returning the first fluid portion from the generator to the absorber, said absorber being operable to condense said first fluid portion and including means for combining the two fluid portions to form a fluid mix for return to said generator, said means for heating said working fluid comprising a burner and said absorber being mounted in the path of the air input for said burner to preheat said air input while the latter serves as cooling air for the absorber.
Claim 5
Dependent Claim
57 words
A power plant as defined in claim 2 and further comprising a heat exchanger coupled between said generator and the inlet port of said fluid-driven device, said heat exchanger also being coupled between said absorber and said generator and being operable to cool the fluid entering said device and to heat the working fluid entering said generator.
Claim 6
Dependent Claim
27 words
A power plant as defined in claim 1 wherein the absorber is mounted in the path of both the primary and secondary air input for said burner.
Claim 7
Dependent Claim
