Wear reduction kit for gas turbine combustors

A wear reduction kit for a combustion system of a turbine comprising:

• a) a plurality of U-shaped inserts for use with a gas turbine transition piece having a peripheral end frame at one end thereof, said peripheral end frame having a continuous U-shaped peripheral slot therein, open in a radially outward direction wherein said plurality of U-shaped inserts are sized and shaped for insertion within said peripheral slot, and further wherein said U-shaped inserts are formed of material having a hardness greater than said end frame;
• b) at least a pair of substantially H-shaped guide block elements for use in securing a transition piece of a gas turbine combustor to a transition piece support, wherein each of said guide block elements is securable to said transition piece and adapted for engagement with a respective pair of cooperating guide finger elements secured to said support;
• and at least a pair of covers for said pair of guide finger elements, and wherein said guide block elements are formed of material having a hardness greater than said finger element covers;
• and
• c) cooperating combustor flow sleeve and combustor liner stop elements wherein the first stop element is adapted to be secured to a combustor flow sleeve and said liner stop element is adapted to be secured to a combustion liner, wherein said first and second stop elements have cooperating engagement surfaces, said engagement surfaces of said flow sleeve stop element having a hardness less than the engagement surfaces of said liner stop element.
