Abstract : The sytem for the protection of the vanes and disc of a gas turbine from abrupt cooling during a sudden shutdown, containing a throttle for air-flow blockage, is distinguished by the fact, that, for the purpose of improving the protection of the turbine vanes and disc from abrupt cooling by providing a gradual flame-out, the system is equipped with an air-throttle-interacting and preclosure-operating system of partial (up to 25% of basic) fuel supply into the combustion chamber after closure of the check valve, and is accomplished in the form of a bypass line with an automatic valve which is gradually closed by means of a servomotor.
