FIELD: gas turbines for combined-cycle plants. SUBSTANCE: method for cooling down coolant of gas turbine of combined-cycle plant that has first evaporation loop with steam drum includes organization of heat transfer between coolant and cooling agent circulating in second evaporation loop connected to steam drum. Coolant temperature is controlled by varying temperature of cooling agent for which purpose condensate is injected into separate evaporation loop. EFFECT: improved cooling conditions of gas turbine. 6 cl, 1 dwg
