Abstract
A closed cycle gas turbine system is described employing a precooler for cooling the gas prior to compression. A closed loop coolant circuit for the precooler employs a heat exchanger. A storage tank is provided for storing a supply of coolant at a temperature substantially lower than the temperature of coolant in the coolant circuit at the discharge side of the heat exchanger. Means selectively circulate the coolant in the storage tank through the precooler to provide a power increase, when needed, in the gas turbine system.
Claims10
A closed cycle gas turbine system comprising, turbine means, compressor means, means for circulating a gas for expansion in said turbine means and compression in said compressor means, a precooler for cooling the gas prior to compression in said compressor means, a closed loop coolant circuit for circulating a coolant through said precooler, said coolant circuit including a heat exchanger for cooling the coolant therein, a storage tank for storing a supply of coolant at a temperature substantially lower than the temperature of coolant in said coolant circuit at the discharge side of said heat exchanger, and means for selectively circulating the coolant in said storage tank through said precooler to provide a power increase in said gas turbine system.
In a gas-cooled nuclear reactor system for producing electrical power and including means for controlling the gas temperature at the outlet of the reactor core, a closed cycle gas turbine system comprising, turbine means, compressor means, means for circulating the reactor coolant gas for expansion in said turbine means and compression in said compressor means, a precooler for cooling the gas prior to compression in said compressor means, a closed loop coolant circuit for circulating a coolant through said precooler, said coolant circuit including a heat exchanger for cooling the coolant therein, a storage tank for storing a supply of coolant at a temperature substantially lower than the temperature of coolant in said coolant circuit at the discharge side of said heat exchanger, and means for selectively circulating the coolant in said storge tank through said precooler to provide a power increase in said gas turbine system.
