ABSTRACT:
An improved cross flow ceramic filter is disclosed for utilization in high temperature, high pressure applications such as found in hot gas cleaning in coal based power generation. The cross flow ceramic filter of the present invention includes a plurality of identical corrugated sheets composed of chopped ceramic fiber matrix material and a plurality of predetermined sized end blocks shaped to fill the cross section passageways formed between the partly spaced corrugations of adjacent sheets of the filter material. One advantage of the corrugated sheet cross flow filter of the present invention is that the filter may be shipped to its site in semi-cured form unassembled. When the filter is received on site, the corrugated sheets are partially separated from each other until passageways of the desired dimension are achieved. Thereafter, the end blocks and glue may be applied between the blocks and the ends of the corrugated sheets and between the apexes of the corrugations where the corrugated sheets overlap. A final cure for the filter may be made with the filter in place in the filter vessel utilizing high temperature, high pressure flue or fuel gas on site.
