Book excerpt: 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. Progress thus far in Phase II (through the first half of the project) includes design of a prototype full size monolithic ceramic cross-flow filter, acceptable material screening tests including room temperature permeability and particulate collection efficiency, design and fabrication of a mold, development of a larger scale process to produce prototypes, and production of some initial prototype filters. The overall primary objective of this Phase II project is to use the ceramic composition data and lab scale process techniques established in Phase I for prototype full scale production and filtration testing/ characterization of monolithic ceramic cross-flow filters.

Book excerpt: High-temperature, high-pressure particulate control is required to protect turbine equipment and to meet environmental stack emissions standards in coal-fueled power systems. Ceramic cross flow filters have high surface area per unit volume for removing particulates from these hot gas streams. A one-piece monolithic ceramic cross flow filter is needed. Mullite bonded, porous, permeable alumina ceramics were made on a lab scale with the Blasch injection forming process. Permeability and other initial targeted property requirements were achieved:>200 cd (1 iwg/fpm), room temperature modulus of rupture1000 psi, particle size 100/200 mesh, pore size 20 microns. It is concluded that it is feasible to use the proprietary Blasch process to form cross flow filters.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced, coal-fueled, power generation systems utilizing pressurized fluidized bed combustion (PFBC) and integrated gasification combined cycle (IGCC) technologies are currently being developed for high-efficiency, low emissions, and low-cost power generation. In spite of the advantages of these promising technologies, the severe operating environment often leads to material degradation and loss of performance in the barrier filters used for particle entrapment. To address this problem, LoTEC Inc., and Oak Ridge National Laboratory are jointly designing and developing a monolithic cross-flow ceramic hot-gas filter. The filter concept involves a truly monolithic cross-flow design that is resistant to delamination, can be easily fabricated, and offers flexibility of geometry and material make-up. During Phase I of the program, a thermo-mechanical analysis was performed to determine how a cross-flow filter would respond both thermally and mechanically to a series of thermal and mechanical loads. The cross-flow filter mold was designed accordingly, and the materials selection was narrowed down to Ca{sub 0.5}Sr{sub 0.5}Zr4P6O24 (CS-50) and 2Al2O3-3SiO2 (mullite). A fabrication process was developed using gelcasting technology and monolithic cross-flow filters were fabricated. The program focuses on obtaining optimum filter permeability and testing the corrosion resistance of the candidate materials.

Book excerpt: Ceramic filter of various configuration have been used to filter particulates from hot gases exhausted from coal-fired systems. Prior ceramic cross-flow filters have been favored over other types, but those previously horn have been assemblies of parts somehow fastened together and consequently subject often to distortion or delamination on exposure hot gas in normal use. The present new monolithic, seamless, cross-flow ceramic filters, being of one-piece construction, are not prone to such failure. Further, these new products are made by novel casting process which involves the key steps of demolding the ceramic filter green body so that none of the fragile inner walls of the filter is cracked or broken.
