Comtois,

There is disclosed a furnace for burning wooden wastes and, more specifically, sawdust and/or barks. The furnace is provided with an oil burner required for starting the fire. The draught from the oil burner fan is directed within a perforated box, located in the combustion chamber of the furnace, and the sawdust or the barks or other wooden particles fall, according to a measured flow, over the perforated box. The sawdust is first alighted by the oil burner flame, and combustion thereafter builds up thanks to the draught from the perforated box. This box draught comprises a vertically-upwardly-oriented vector, for alighting the wood particles before the latter reach the box, and a horizontal vector extending toward the interior of the furnace to force the burning particles away from the side wall of the furnace. The system includes measured flow feeding system for the sawdust and/or the bark, and having a pair of flap-doors to prevent the escape of smoke from the furnace.
