Patent number: 8734555Abstract: This disclosure describes examples of a seal element that can prevent leaks that occur due to sagging and/or displacement of a filter device from the tubesheet in a power generating system. The seal element can have a non-uniform profile that defines a material thickness for the seal element. In one example, the non-uniform profile defines an area or section of the seal element that is thicker relative to other areas or sections of the seal element. The thicker area corresponds to certain positions on the filter device that are susceptible to movement that can occur, e.g., due to particulate build-up during operation of the turbo-machine.Type: GrantFiled: June 12, 2012Date of Patent: May 27, 2014Assignee: BHA Altair, LLCInventor: Etienne Rene Jarrier
