Hot gas particulate filters are key components for the successful commercialization of advanced coal-based power-generation systems such as Pressurized Fluidized-bed Combustion (PFBC), including second- generation PFBC, and Integrated Gasification Combined Cycles (IGCC). Current generation monolithic ceramic filters are subject to catastrophic failure because they have very low resistance to crack propagation. To overcome this problem, a damage -tolerant ceramic filter element is needed. Westinghouse, with Techniweave as a major subcontractor, is conducting a three-phase program aimed at providing advanced candle filters for a 1996 pilot scale demonstration in one of the two hot gas filter systems at Southern Company Service`s Wilsonville PSD Facility. The Base Program (Phases I and II) objective is to develop and demonstrate the suitability of the Westinghouse/Techniweave next generation composite candle filter for use PFBC and/or IGCC power generation systems. The optional Task (Phase III, Task 5) objective is to fabricate, inspect and ship to Wilsonville 50 advanced candle filters for pilot scale testing.
