Abstract
An improved and high capacity gas igniter for furnaces and burners. The igniter can include an igniter tip that is annular in shape and includes various holes of different sizes and angular projections distributed throughout. The igniter tip may utilize a slip-joint-like mechanism or sleeve that connects inner and outer tubes of a guide tube that allows the inner tube to slide when undergoing thermal expansion. This configuration alleviates stress from building up on the inner tube and igniter tip, preventing damage.
