A gas turbine is provided in which the quantity of cooling air required to cool the turbine is reduced by the evaporative cooling of air bled from the compressor discharge for cooling purposes. The evaporative cooling is accomplished by spraying pressurized water into a bleed pipe which diverts the cooling air from the compressor discharge to the turbine.
