Abstract

Abstract In a power plant which furnishes low-grade heat to a Rankine cycle turbo-generator (24, 28) operating with an organic fluid, a fast-starting prime mover (36) is selectively coupled to the generator (28), the generator capacity of the generator (28) being oversized relative to the individual capacities of the turbine (24) and the prime mover (36).

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 55 words
A power plant that furnishes low grade heat to a Rankine cycle turbogenerator (24, 28) operating with an organic fluid, characterized in that a fast starting prime mover (36) is selectively coupled to the generator (28) whose generating capacity is oversized relative to the individual capacities of the turbine (24) and the prime mover (36).
Claim 2
Dependent Claim 55 words
A power plant that furnishes low grade heat to a Rankine cycle turbogenerator (24, 28) operating with an organic fluid, characterized in that a fast starting prime mover (36) is selectively coupled to the generator (28) whose generating capacity is oversized relative to the individual capacities of the turbine (24) and the prime mover (36).
Claim 3
Dependent Claim 18 words
A power plant according to Cla.im 1 characterized in that the prime mover is an internal combustion engine.
Claim 4
Dependent Claim 18 words
A power plant according to Cla.im 1 characterized in that the prime mover is an internal combustion engine.
Claim 5
Dependent Claim 24 words
A power plant according to Claim 2 characterized in that the turbine (24) and the internal combustion engine (36) are of substantially equal capacity.
Claim 6
Dependent Claim 17 words
The invention of claim 2 characterized in that the internal combustion engine (36) is a diesel engine.
Claim 7
Dependent Claim 94 words
A peaking of peak shaving power plant for operating from a source of low grade heat; a Rankine cycle turbine utilizing an organic working fluid; a boiler responsive to said low grade heat for vaporizing the working fluid; and a. generator driven by the turbine, characterized in that the generator has a generating capacity in excess of the capacity of the turbine; and characterized in the provision of a prime mover with a work capacity less than the generating capacity of the generator; and means for selectively coupling the prime mover to the generator.
Claim 8
Dependent Claim 94 words
A peaking of peak shaving power plant for operating from a source of low grade heat; a Rankine cycle turbine utilizing an organic working fluid; a boiler responsive to said low grade heat for vaporizing the working fluid; and a. generator driven by the turbine, characterized in that the generator has a generating capacity in excess of the capacity of the turbine; and characterized in the provision of a prime mover with a work capacity less than the generating capacity of the generator; and means for selectively coupling the prime mover to the generator.
Claim 9
Dependent Claim 22 words
A peaking or peak shaving power plant according to Claim 5 characterized in that the prime mover is an internal combustion engine.
Claim 10
Dependent Claim 22 words
