Title:
【発明の名称】熱回収方式蒸気冷却ガスタービン
Document Type and Number:
Japanese Patent JPH10510897
Kind Code:
A
Abstract:
A recuperative steam cooled gas turbine in which steam used to cool the turbine section is subsequently introduced into the combustors, thereby recuperating the heat absorbed by the steam during cooling. The steam is generated in a heat recovery steam generator and then directed to a manifold within the turbine shell. From the manifold, the steam flows through passages formed within the interior of the vane by a baffle, thereby cooling the vane and heating the steam. The steam is then discharged from the vane into a chamber that collects the compressed air from the compressor. In the chamber, the heated steam mixes with the compressed air and the air/steam mixture then flows into the combustors, where it serves to reduce NOx generation from the combustors and increase power output from the turbine.
