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.
Claims18
An apparatus for the combustion of solid particulate fuel comprising:
- a stationary grate including a perforated plate for receiving said solid particulate fuel;
- displaceable means positioned in a plane above said grate, movement of said displaceable means displacing spent solid particulate fuel from said stationary grate, said displaceable means including a rotatable member;
- and
- a burning cap positioned over said stationary grate, said burning cap defining a combustion chamber above said stationary grate, said burning cap including a baffle that divides said combustion chamber into a primary half and a secondary half, said burning cap also including an aperture for allowing said solid particulate fuel to be introduced into said primary half.
