Abstract: A ceramic filter construction having particular use for removing particulate material in a catalytic incineration system. The ceramic filter is mounted in a plenum through which exhaust gas containing particulate material is conducted. Particulate material is removed from the gas stream as it flows through the ceramic filter. To automatically clean the filter, a fuel burner is located upstream of the filter and extends across the plenum and divides the plenum into a pair of flow paths which merge downstream of the burner adjacent the filter. During the cleaning cycle, the burner directs a flame toward the filter. A damper is positioned in each flow path and the dampers can be independently operated to vary the volume of gas in each flow path and deflect the flame to cause the flame to translate across the surface of the filter to burn off combustible material adhered to the filter.
