Abstract
The present invention relates to a burn pot for particulate combustors, particularly of the type used for burning particulate fuel such as pellets. The burn pot includes a burn pot body surrounded by an air plenum in which air is delivered and exhausted through openings in side, front, and bottom walls of the burn pot body. A rearwardly inclined back wall is moved by a driver to reciprocate forwardly and rearwardly toward and away from the front wall. The back wall is inclined opposite to the front wall in order, upon reciprocating motion, to engage and move the particulate material toward the front wall, bunching it for more efficient combustion, clearing the openings in the burn pot walls, and forcing ash up the front wall and over the upper ash discharge edge thereof. The burn pot and back wall are removably mounted within the firebox to facilitate removal for cleaning, maintenance or replacement.
