Abstract
An exhaust gas diffuser interface includes a stainless steel shell with varying levels of insulation. The varying levels of insulation concentrate thermal expansion and contraction at the turbine outlet end allowing it to be connected to the outlet by way of a seal weld. This construction allows expansion and contraction of the diffuser interface in unison with the attached turbine outlet, as well as the diffuser inlet.
Claims13
An interface adapted to be positioned between a gas turbine and a downstream exhaust gas apparatus, said interface comprising:
- an interface connector to be attached to the exhaust gas outlet of said gas turbine;
- a flexible member attached to said interface connector;
- a thermal transition member downstream from said flexible member and attached to said downstream apparatus;
- and
- thermal insulation mounted on said thermal transition member of continuously increasing thermal resistivity with increasing distance from said exhaust gas source along substantially the entire length of said transition member.
An exhaust gas interface between a gas turbine and a downstream exhaust apparatus, said interface comprising:
- a sealing member adapted to be welded in a gas tight sealing arrangement to the exhaust outlet of said gas turbine;
- a flexible member secured to said sealing member constructed to thermally flex an amount corresponding to the thermal expansion and contraction of said exhaust outlet;
- and
- a transition member extending between said flexible member and said downstream exhaust apparatus and having increasing internal thermal insulation along substantially the entire length of said transition member as said transition member extends in the downstream direction.
