Combustors with quench inserts

A method for installing an insert in an air admission hole of a combustor liner, the insert including a body portion, a shoulder, and an inlet portion and the combustor liner having a liner wall with a first side and a second side, the method comprising the steps of:

• inserting the inlet portion through the air admission hole from the first side to the second side until the shoulder abuts the hot side, wherein the air admission hole has a generally non-circular shape;
• and
• deforming the inlet portion such that the inlet portion has an outer diameter greater than a diameter of the air admission hole such that the inlet portion and the shoulder capture the combustor liner to retain the insert relative to the air admission hole, wherein the deforming step includes swaging the body portion of the insert such that an outer circumference of the body portion matches the generally non-circular shape of the air admission hole.
