摘要： 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.

摘要： A refractory brick particularly suited for constructing a diffusor wall for an industrial heat source. The brick includes a substantially tubular body having a first end, a second end opposed to the first end, an inner surface defining a passageway extending in the longitudinal direction of the body from the first end to the second end, and an outer peripheral surface extending from the first end to the second end. The outer peripheral surface has a complementary shape that allows mating of a plurality of the bricks to form cooperatively a diffusor wall. Mating means is formed on or in the outer peripheral surface for engaging corresponding mating means formed on or in outer peripheral surfaces of adjacent bricks when assembled as a diffusor wall.
