FF 03 10 09 "Development of Metallic Filters for Hot Gas Cleanup in Pressurized Fluidized Bed Combustion Applications" by Iver E. Anderson, Brian Gleeson and Robert L. Terpstra, Iowa State University, Ames, IA. 13 p.
Alternative alloys derived from the wide array of aerospace superalloys will be developed for hot gas filtration to improve on both ceramic filters and "first-generation" iron aluminide metallic filter materials. New high performance metallic filters should offer the benefits of non-brittle mechanical behavior at all temperatures, including ambient temperature, and improved resistance to thermal fatigue compared to ceramic filter elements, thus improving filter reliability. A new powder processing approach also will be established that results in lightweight metallic filters with high permeability and weldability for enhanced capability for filter system manufacturing.
