1. A post for contacting an exhaust liner having a first net pressure at a first region, the post comprising:
an interface region;
a periphery for contacting the exhaust liner in sealing engagement with the exhaust liner, the periphery defining a perimeter of the interface region;
a shank extending from the periphery and to a first pressure region; and
a hollow passageway internal to the shank, providing fluid communication between the interface region of the post and the first pressure region to create a pressure differential adjacent the interface region;
wherein the first pressure region results in a second net pressure at the interface region, urging the exhaust liner adjacent the interface region against the periphery, the second net pressure greater than the first net pressure, while preventing fluid leakage across the perimeter between the exhaust liner and the interface region.
