Abstract
A combustor wall louver for ducting a flow of compressed air through an inlet opening in the combustor wall from a source of compressed air outside the combustor where the louver is a circumferentially extending member, mounted to an interior surface of the combustor wall and covering the inlet opening with outlet openings fed by a channel in flow communication between each outlet opening and the inlet opening. Preferably, the circumferential member is made of arcuate segments of cast metal removably mounted to the interior surface of the combustor wall with threaded studs.
Claims17
A gas turbine combustor assembly comprising:
- a combustor having a liner wall and a louver assembly extending circumferentially around an interior surface of the liner wall and threadingly mounted thereto, the assembly including a plurality of arcuate segments disposed end-to-end, each segment having circumferentially extending side walls, the sidewalls disposed angularly towards one another to provide each segment with a narrow closed end and a wider open end, the narrow end disposed inwardly relative to the combustor, the wider end mating with the liner wall, each segment co-operating with the liner wall to define an enclosed space therebetween, the enclosed space communicating with at least one inlet opening defined in the liner wall and a plurality of outlet openings defined in the segment, wherein each segment includes end bulkheads extending between lateral ends of the side walls, the bulkheads and sidewalls bounding therebetween the enclosed space and, wherein each bulkhead includes at least one outlet opening.
A louver segment for a gas turbine combustor, the combustor having a circumferentially extending liner wall, the louver segment comprising:
- an arcuate member adapted to extend partially circumferentially around an interior surface of the liner wall, the member having circumferentially extending side walls, the side walls disposed angularly towards one another to thereby provide the segment with a narrow closed end and a wider open end, the open end adapted to mate with the liner wall to define an enclosed space therebetween, the enclosed space communicating with a plurality of outlet openings defined in the segment, wherein the segment includes end bulkheads extending between lateral ends of the side walls to bound therebetween the enclosed space and, wherein each bulkhead includes at least one outlet opening, the enclosed space adapted to communicate with at least one inlet opening defined in the liner wall.
