Abstract

DC60 (10/07/44) Method of repairing annular vaporization cooled liner (12,14) for the combustion chamber (10) of a gas turbine. The ring-shaped part (34) of the liner (12,14), including the damaged area. is removed from between the upstream (30) and downstream (32) sections of the liner (12,14). The sheet metal is formed into an annular replacement (40) with axial seams. At least one line (42) extending between the source end (44) and the destination end (46) of the replacement part (40). The replacement part (40) is sized. and the same shape as the Removed annular (34) of the liner (12,14) upstream (44) of the annular section removed The forming is connected to the upstream (30) portion of the liner (12,14) and the downstream (46) of the formed ring segment is connected to the downstream segment (32) of the liner.

Claims (8)

Disclaimers (all) that will not appear on the advertisement page: 1.Method of repairing the cooled liner by damaged annular vaporization of gas turbine combustion chamber. Consists of steps Removing the liner ring, including damaged areas from during The source and the destination of the liner. Sheet metal forming is a replacement for the ring shape. With seams along At least one axis Filed between the ends of the origin Of the replacement part and the destination end Will be opposite the end of the source said The replacements are made to be the same size and shape as the aforementioned removeable ring portion of the liner. Connection of the upstream end Of the replacement part instead of the formed ring To the aforementioned part of the liner and the end-end connection of the formed annular replacement. With the destination side of the liner 2. Method as described in claim 1, where seams are formed by welding. Model using a liptron 3. Method as stated in claim 1, where the formed ring portion is connected to the said source. And with the destination side thereof By electron beam welding 4. Method as set out in Clause 1, where the replacement is deformed. Permanently to keep in shape Finally, after being connected to the source and destination sections of the liner. 5.The method described in claim 1, where the liner is heat treated. After the replacement part Is connected to the source resistance. And the destination of the liner 6. Method as described in claim 1, where the heat holes are machined in the liner after the replacement part. Is connected to the source part And the destination of the liner 7. Method as described in claim 6, where heat holes are machined in the liner at a different location than heat holes in the removed ring part. 8. Method as described in claim 6, where the heat holes are machined in the liner with a different size than the vent holes in the removed ring part.
