Abstract: A wood burning stove is formed with double front and rear side walls of heat conductive metal spaced apart by heat conductive spacer fins and providing air passageways by which room air is heated by conduction from the walls which are heated by the burning of wood deposited on a firebox floor supported in heat conducting relationship with the inner side walls. A catalytic converter is disposed over the fire area in the upper portion of the stove, and is arranged to receive preheated fresh secondary air which mixes with hot, incompletely combusted compounds from the fire and, in the presence of the catalyst, induces a secondary combustion of the substances. This mixture is channeled into a heat extraction chamber where the secondary combustion is completed and the resultant heat is transferred to the metal body of the stove. An exhaust passageway is provided for releasing the products of complete combustion into the atmosphere.

Abstract: A wood burning stove is formed with double front and rear side walls of heat conductive metal interconnected by heat conductive spacer fins and providing air passageways by which room air is heated by conduction from the walls which are heated by the burning of wood deposited on a firebox grate made up of spaced bricks supported by metal holders secured in heat conducting relation to said inner side walls. The rear side air passageway is divided into central and outer vertical sections the central one of which is closed at the bottom end and communicates with the atmosphere through an opening in the outer wall intermediate its vertical ends and with the stove interior above the firebox and below the grate through openings in the inner wall intermediate its vertical ends and adjacent its bottom end, respectively.
