Abstract
Abstract A heat exchanger in a close cycle gas turbine power plant has, on its heat abduction side, a system of cooling units connected to it by means of which the efficiency of the plant is considerably increased. Such units consist of evaporators and vapor turbines with condensers and air coolers, the vapor turbines being driven by vapors generated in the evaporators. The latter, in turn, are heated by the heat abduction side of the heat exchanger in the main cycle. The exhaust vapors are precipitated in condensers and cooled down by air coolers and recoolers and partly circulated back to the heat abduction side of the heat exchanger in the main cycle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A closed cycle power plant, comprising a gas turbine having an intake and an exhaust, a work gas cooling heat exchanger having a heater side and a heat abduction side, said heater side of said heat exchanger being connected between said intake and said exhaust of said gas turbine, an air cooler, an evaporator having a liquid chamber and a vapour chamber, said liquid chamber of said evaporator being connected to said heat abduction side of said heat exchanger through said air cooler, said vapour chamber of said evaporator being also connected to said heat abduction side of said heat exchanger through a condensation vapour turbine.
Claim 2
Dependent Claim
106 words
A closed cycle power plant, comprising a gas turbine having an intake and an exhaust, a work gas cooling heat exchanger having a heater side and a heat abduction side, said heater side of said heat exchanger being connected between said intake and said exhaust of said gas turbine, an air cooler, an evaporator having a liquid chamber and a vapour chamber, said liquid chamber of said evaporator being connected to said heat abduction side of said heat exchanger through said air cooler, said vapour chamber of said evaporator being also connected to said heat abduction side of said heat exchanger through a condensation vapour turbine.
Claim 3
Dependent Claim
19 words
The closed cycle power plant as claimed in claim 1, further comprising a pipe conduit bypassing said vapour turbine.
Claim 4
Dependent Claim
44 words
The closed cycle power plant as claimed in claim 1, wherein said evaporator has a plurality of vapour chambers and said vapour turbine has a plurality of stages and each of said vapour chambers is connected to a different stage of said vapour turbine.
Claim 5
Dependent Claim
60 words
The closed cycle power plant as claimed in claim 1, further comprising a mixing condenser and cooler means connected in series with and downstream from said vapour turbine, said cooler means connected with said mixing condenser comprising a dry air cooler and being provided with a branch connected to said heat abduction side of said work gas cooling heat exchanger.
Claim 6
Dependent Claim
53 words
The closed cycle power plant as claimed in claim 1, further comprising valve means between said heat abduction side of said work gas cooling heat exchanger and said evaporator, and means for controlling said valve means dependent on the pressure prevailing in the heat abduction side of said work medium cooling heat exchanger.
Claim 7
Dependent Claim
100 words
The closed cycle power plant as claimed in claim 1, further comprising a surface condenser with a cooler side connected downstream from said vapour turbine, a wet air cooler connected to said cooler side of said surface condenser, a dry air cooler downstream said liquid chamber of said evaporator, a recooler having a cooler side and a heater side, said cooler side of said recooler being arranged downstream said dry air cooler, and pipe conduit means connecting said heater side of said recooler to said cooler side of said surface condenser said pipe conduit means bypassing said wet air cooler.
