Vapor power plant

Claim 1

A vapour power plant driven with a working fluid vapourized from cool liquid including trichromonofluoromethane having a freezing point lower than minus 30* C and a boiling point lower than 95* C, comprising an evaporator delivering a vapourized working fluid, a prime mover communicating at its inlet port with said evaporator for receiving the vapourized working fluid therefrom, a regulator valve disposed between said evaporator and said prime mover for adjusting the flow of said vapourized working fluid to be delivered to said prime mover a vapour condenser communicating at its inlet port with an outlet port of said prime mover for receiving and liquefying an exhaust discharged therefrom, a liquid reservoir communicating at its inlet with said condenser for temporarily storing a cool liquid fed therefrom and communicating at outlet port with an inlet port of said evaporator through a first pump interposed between said reservoir and said boiler and a cooling means communicating at its inlet port with a second outlet port of said reservoir through a second pump and at its outlet port with a second inlet port of said condenser, said first and second pump feeding said cool liquid in said reservoir to said evaporator and said cooling means, respectively, the liquid forcedly cooled in said cooling means being fed into said condenser for cooling and liquefying the exhaust discharged from said prime mover in the succeeding cycle.
