Filtration system configurations particularly useful for cleaning high temperature raw gas containing fine particulates such as that discharged from coal gasification and fluidized bed combustion processes. Thin filter elements, having elongated clean channels on one side of a gas permeable ceramic membrane and shorter dirty channels on the other side, extend radially outward from a central duct. Raw gas flows about and through the filter elements, and clean gas which permeates the membrane enters the duct. The elements are cleaned by a back pulse of clean air, spitting the particulates to the bottom of the containing vessel and through an outlet. A high density filter packing within a containing pressure vessel is achieved by nesting a plurality of the duct and filter element modules, or through other orientations and filter element configurations.
