Liquid injection in a gas turbine during a cooling down phase

The invention relates to a method for cooling a gas turbine comprising a rotor, said method being carried out after the operation of the gas turbine and whereby the rotor is driven at least intermittently during a cooling phase at a reduced nominal speed. To provide a gas turbine with a reduced down...

Zusammenfassung:The invention relates to a method for cooling a gas turbine comprising a rotor, said method being carried out after the operation of the gas turbine and whereby the rotor is driven at least intermittently during a cooling phase at a reduced nominal speed. To provide a gas turbine with a reduced down time, a liquid is introduced at least intermittently into the air stream upstream of the compressor during the cooling phase.
