Abstract
A method for cooling down a gas turbine, wherein the gas turbine is run down from the power operation thereof to cool-down operation, and wherein a liquid is sprayed into air sucked in by a compressor of the gas turbine during the cool-down operation, and wherein the liquid is sprayed into the sucked-in air in dependence on a humidity of the sucked-in air, a flow velocity of cooling air flowing in the gas turbine in the region of at least one flow-guiding component of the gas turbine, which component is to be cooled, and a temperature difference between a temperature of the sucked-in air and a temperature of the at least one flow-guiding component of the gas turbine.
