Abstract

Abstract This disclosure relates to a wood burning stove which includes an innermost combustion chamber within and generally spaced from an intermediate air-circulating chamber in turn generally within an outermost chamber, all of the chambers having generally spaced top, rear, bottom and pairs of side walls, all of the side walls having openings and ducts associated therewith through which air is introduced into the combustion chamber, all of the top walls having openings housing a duct through which products of combustion are exhausted from the combustion chamber, openings in the bottom walls of the intermediate and outermost chambers through which hot air is directed from the hot-air chamber for subsequent utilization, damper means associated with the top wall of the combustion chamber and the bottom wall of the intermediate chamber for respectively regulating the flow of gases through the openings or ducts associated therewith, and openings in the rear walls of the outermost and intermediate chambers through which air is blown by an associated blower for circulating within the hot-air chamber and being blown outwardly therefrom through the openings of the bottom walls and the ducts associated therewith as well as front openings in a front wall of the stove.
