This disclosure describes an apparatus which will enable high temperature filtration of particulate laden gases through a composite filter that consists of a layer of in-expensive granular filter media that is supported on a high temperature porous media. It also describes a method for regenerating the composite filter media when the pressure drop across said media becomes too high. The purpose of such a high temperature composite filter is to inexpensively facilitate the filtration of high temperature gases bearing sticky particulate in a low pressure drop continuous and reliable manner. Particulate from hot gases are captured by the granular filter media. When the pressure drop across a filter element becomes too high, a reverse flow of gas through the high temperature porous media causes the granular media to slide down the inclined porous media. New granular media is introduced at the top of the inclined filter element to replace granular media that is discharged from the bottom end of the inclined filter element.
