Constant pressure air storage installation with water supply for gas turbine power plants

摘要

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.
