Abstract

A combustor casing exit ring (208, 210) is provided including a membrane slot (302) and a sacrificial plate (402) covering at least one wall of the membrane slot. During gas turbine operation, the sacrificial plate (402) accepts wear from contact with a component inserted into the membrane slot. A combustor (112) including an outer casing surrounding a combustion chamber (202), the outer casing including an inner combustor liner having an end portion comprising a combustor casing exit ring is also provided.
