A filtering apparatus for separating particulates from a hot gas stream using hollow, tubular filter elements has a housing with a laterally extending support plate for the filter elements separating the housing into upper and lower sections. The tops of the filter elements are biased against the support plate and the bottoms thereof restrained from lateral movement by restraining rings. Blowback and purge gas systems provide for cleaning of the filter elements and maintenance of the blowback system clear of the solids or condensation products that might...


In an apparatus for filtering of particulates from a particulate-containing high temperature gas stream wherein the gas stream is passed through the walls of a hollow, tubular filter element having an outer wall and clean gas discharged from an open end of the filter element and particulates collected on the outer wall thereof, with means provided to pass a blowback gas into the open end of the filter element to discharge collected particulate material from the outer wall thereof and clean the same, the improvement comprising: a housing, having a wall wi...
