Abstract
A regenerable filter for use with exhaust gas streams containing combustible particles, the filter including a filter medium upon which the particles build up as the filter medium removes the particles from the gas stream, a scraper to remove the particles, except for a precoat, from the filter medium, and a burner to burn the removed particles outside the main exhaust gas exit.
