Method and the device in order the gas turbine combuster liner and the transition piece joint cooling and it dilutes to adjust

摘要

A combuster liner includes a forward end and an aft end and the aft end having a reduced diameter portion and a cooling and dilution sleeve overlying the reduced diameter portion thereby establishing a cooling plenum therebetween. A plurality of cooling and dilution air entry holes are formed in the cooling and dilution sleeve and a plurality of cooling and dilution air exit holes formed adjacent an aft edge of the liner such that, in use, cooling and dilution air flows through the cooling and dilution air entry holes, and through the plenum, exiting the cooling and dilution air exit holes and thereby cooling and dilution tuning the aft end of the combuster liner without having to remove the transition piece.
