Igniter tube and method of assembling same

摘要

An igniter tube assembly (100) includes an axis of symmetry (134) extending therethrough, an igniter tube (110) that includes a first opening extending coaxially therethrough having a diameter sized to receive a portion of the igniter (62) therethrough such that the igniter tube circumscribes the igniter and such that a gap is defined between the igniter tube and the igniter, a ferrule (200) coupled to the igniter tube, and a plurality of cooling air openings (140) extending through at least one of the igniter tube and the ferrule to facilitate channeling cooling air into the gap.
