Exhaust plenum for gas turbine

摘要

An exhaust plenum for connection to an exhaust outlet portion of a gas turbine for receiving turbine exhaust gas. The exhaust plenum includes a first wall. The first wall includes a seal attachment component in thermal contact with an exterior shell of the first wall and is adapted for attaching an annular flex seal to the first wall. The seal attachment component extends generally around a perimeter of the inlet of the exhaust plenum, and is thermally insulated from an interior space of the exhaust plenum.

1. An exhaust plenum for connection to an exhaust outlet portion of a gas turbine for receiving turbine exhaust gas therefrom, the exhaust plenum comprising:
an interior space; a first wall defining an inlet of the exhaust plenum through which exhaust gas from the exhaust outlet portion of the gas turbine enters the interior space of the exhaust plenum; and a second wall defining an outlet of the exhaust plenum through which exhaust gas exits the interior space of the exhaust plenum, wherein the first wall includes
an exterior shell having an interior-facing surface,an interior liner having an exterior-facing surface, wherein the exterior-facing surface of the interior liner generally opposes and is spaced apart from the interior-facing surface of the exterior shell to at least partially define a wall cavity therebetween, anda seal attachment component in thermal contact with the exterior shell of the first wall and adapted for attaching an annular flex seal to the first wall, the seal attachment component extending generally around a perimeter of the inlet of the exhaust plenum, wherein the seal attachment component is thermally insulated from the interior space of the exhaust plenum.
