Title:
STEAM INJECTION NOZZLE DESIGN OF GAS TURBINE COMBUSTION LINERS FOR ENHANCING POWER OUTPUT AND EFFICIENCY
Document Type and Number:
WIPO Patent Application WO2002014672
Kind Code:
A9
Abstract:
A steam injection nozzle system for injecting steam into a combustion liner (10) of a gas turbine for enhancing power output and efficiency of the gas turbine. The combustion liner has a plurality of dilution holes for supplying air to the combustion chamber to create turbulence. A steam manifold (51) surrounds the combustion liner and has a plurality of steam injection nozzles (55). Each steam injection nozzle being disposed opposite a corresponding dilution hole, without touching the combustion liner, for injecting the steam directly into the combustion liner through the dilution holes. The steam is injected without altering an existing amount of air through the plurality of dilution holes, resulting in a constant amount of air through the plurality of dilution holes independent of the amount of steam injected therein within a predetermined range of steam.
