Abstract
An apparatus for burning solid particulate fuels in a top-fed combustion system that permits the use of fuels that produce large amounts of ash and clinkers. The apparatus displaces the ash and clinkers from the grate which, if not removed, would adversely affect the heat output and efficiency of combustion. The apparatus uses a rotating reciprocating member that removes the ash and clinkers from the grate that supports the solid particulate fuel during combustion.
