Abstract
Either atmospheric pressure or superatmospheric pressure high temperature gases, as from a gasifier or other circulating fluidized bed reactor, are filtered using monolithic ceramic filter elements mounted in an advantageous manner within a vessel. At least one generally upright hollow chamber element is mounted by a tube plate within the vessel, and has at least one gas impervious side wall having a column of openings in it, an open end, and a closed end. Monolithic ceramic filter elements are mounted in the openings. A number of chamber elements are typically provided, e.g. mounted in a circular pattern, and/or mounted to extend downwardly from a top tube plate and upwardly from a bottom tube plate. Backflushing of the filter elements dislodges separated particles, which fall down to the bottom of the vessel and are removed through a central discharge opening.
