EXHAUST GAS DIFFUSER INTERFACE

摘要

An improved 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. The result is an interface that is less expensive, easier to fabricate and install, and capable of achieving a longer service life.
