| Abstract |
Ceramic cross-flow filters were designed to provide high temperature, high pressure removal of particulates from hot gas streams in coal fueled power systems, with the benefit of high surface area per unit volume. An important need has been identified as a one-piece monolithic ceramic crossflow filter, rather than the most recent segmented filter that has been known to delaminate/separate in service. Current ceramic technology has proved incapable of forming a complex one-piece shape such as this, with an acceptable permeable, porous ceramic material. Blasch's unique and proprietary injection mold ceramic forming process has commercially produced complex shapes of this nature for many years, but of a non-permeable ceramic. In the earlier SBIR Phase I work, permeable, porous ceramic compositions were developed, targeted to meet the filtration and other requirements of crossflow filters. In this SBIR Phase II effort, the ceramic composition data and lab scale process techniques established in Phase I are being used as the basis for prototype production of full-size monolithic ceramic cross-flow filters. After production, these prototypes will be subjected to filtration testing, followed by post-test characterization. |
