The goal of this program was to develop and fabricate an initial set of ceramic fiber reinforced, ceramic matrix composite, hot gas candle filters for testing in a simulated pressurized fluidized bed combustion (PFBC) environment. Four full-scale ceramic fiber reinforced candle filters were fabricated in a multi step process. The substrate was filament wound using Nextel{trademark} 312 yarn and then coated with silicon carbide by chemical vapor deposition (CVD) to form a ceramic composite shape that provides the candle`s structural shape, toughness, and strength. Filter layer material was applied over the surface and then bonded with silicon carbide in a chemical vapor infiltration, CVI, step.
