Part of high-pressure air is extracted from the vicinity of the final stage of a compressor and is introduced into a water spraying chamber, and water at the normal temperature is injected into the high-pressure air from a nozzle installed in the water spraying chamber, to prepare a cooled coolant. The coolant sometimes contains water drops. The cooled coolant is fed into coolant passageways which are provided inside a moving blade in a manner to extend from the root part to the tip of the moving blade. When the coolant passes through the passageways, th...
A method of cooling a moving blade of a gas turbine in which high-pressure air from a compressor is passed through a combustor to make it a combustion gas, the combustion gas is introduced into a main gas passageway with a cascade including the moving blade disposed therein, and power is taken out by expansion of the combustion gas, comprising the steps of: extracting part of the high-pressure air from the compressor in order to use it for cooling; spraying water into the extracted air, and mixing water drops with the air and cooling said air, to prepare...
