Automated ash removal system for a pellet stove using a motor to move part of the floor of the firebox

摘要

A pellet stove that includes a firepot assembly is disclosed. The firepot has a bottom plate slideable along rails to move between a closed position during combustion in the firepot and an open position during ash removal. Also disclosed is a firebox (201) or combustion enclosure includes a plurality of airfoils (202) formed on the inner and outer surfaces of the enclosure to facilitate heat exchange between exhaust gases flowing across the inner surface of the enclosure and air blown across the outer surface of the enclosure. The airfoils and enclosure may be of integral unibody construction. A user adjustable a wall control unit can set parameters controlling the stove. A stove control unit receives the parameters and automatically controls fuel feed rate, ignition, convection blower, combustion blower, and/or firepot cleaning based on the one or more parameters.
