Abstract
A constant pressure air storage supply for gas turbine power plants which comprises a cavern and a water supply. In order to prevent the blowing-out of the cavern water through the riser tube there is provided within such riser tube a servomotor-operated regulation valve. This valve, upon occurrence of a certain pressure drop within the cavern, which signals the blow-out danger, is controlled by a pulse transmitter and throttles to the requisite degree the outflow from the cavern.
Claims2
A constant pressure air storage installation having a water supply for gas turbine power plants containing a gas turbine, comprising:
- a subterranean cavern;
- an air compressor;
- an electric motor for driving the air compressor independently of the gas turbine;
- said subterranean cavern serving for the storage of compressed air delivered by the air compressor;
- connection lines extending between the cavern and the air compressor and the gas turbine;
- a compensation basin;
- a riser tube connecting the compensation basin with the cavern;
- and
- means for regulating the throughflow resistance within the riser tube in dependency upon a course as function of time of a pressure drop arising within the cavern, in order to safeguard against unintentional outflow of water out of the cavern and through the riser tube, to thereby prevent blow-out of water from the cavern due to the action of the compressed air in the cavern.
