ABSTRACT:
The improved liner comprises a base plate that mounts to the wall of the nozzle, at least one inner tube having a plurality of leg supports thereon for mounting to the base plate, a cylindrical seal attached to the bottom of the inner tube, and an outer tube loosely mounted about the inner tube and seal with the leg supports extending therethrough. The outer tube is not fixedly attached to the inner tube or seal or leg supports and thus can move in response to pressure and temperature changes. Both the inner and outer tubes have holes therein to allow for the flow of cooling air from the inner tube to the outer tube to the hot area of gas flow.
