Benefits of technology

[0005]Aspects and advantages of the invention are set forth below in the following description, or may be obvious from the description, or may be learned through practice of the invention.

Problems solved by technology

Temperature changes associated with the combustor may produce uneven expansion between the end cover and the insert.
Over time, the braze or weld joints between the end cover and the insert may crack or fail, possibly resulting in internal leakage between the various passages in the end cover and / or insert.
However, geometric constraints preclude adequate seating surfaces for the replacement seals in some end cover designs.

Abstract

A combustor includes an end cover with a borehole through the end cover. The combustor further includes an insert in the borehole in the end cover and at least one continuous passage through the end cover and the insert. A ring is fixedly connected to the end cover with a seal between the ring and the insert. A method for repairing a combustor includes fixedly connecting a ring to an end cover and installing a replacement insert in the end cover. The method further includes installing a seal between the ring and the replacement insert.

Description

FIELD OF THE INVENTION[0001]The present invention generally involves a combustor and a method for repairing a combustor. In particular, various embodiments of the present invention provide a system or method for modifying or repairing an end cover in the combustor.BACKGROUND OF THE INVENTION[0002]Combustors are known in the art for igniting fuel with air to produce combustion gases having a high temperature and pressure. For example, gas turbine systems, aircraft engines, and numerous other combustion-based systems may include one or more combustors that mix a working fluid, such as air, with fuel and ignite the mixture to produce high temperature and pressure combustion gases. The combustion gases may then be used to rotate a turbine, provide thrust, or perform various other forms of work.[0003]Each combustor generally includes an end cover and a liner that surround and define a combustion chamber, and the working fluid may flow along the outside of the liner to remove heat from th...
