ABSTRACT:
Hot gas filter for separating solid particles carried along in high temperature or waste gases having a filter casing made of heat-resistant brickwork, in which there is provided at least one oblong filter cell one end of which ends in a hot gas supply duct whereas the other end is tightly closed by a removable cover. The walls of the filter cell are at least partly made of perforated bricks, through which the hot gas entering the filter cell may overflow to a treated gas discharge duct. The filter cell is lined over the whole length thereof with a replaceable filter hose of heat resistant fabric or tissue, preferably non-woven ceramic fiber fabric or a fabric of ytrium-oxide stabilized zircon-oxide fibers.
