ABSTRACT:
An improvement in a woodburning stove of the type including an exhaust flue opening; a combustion chamber for primary combustion, having an access door, a support for wood to be burned and a primary air inlet means for supplying primary air to support primary combustion of the wood to produce flue gases containing combustible particulate material; conduit means for directing the flue gases from the combustion chamber to the flue opening in a preselected path; and, secondary combustion means for burning the particulate material in the flue gases before the flue gases pass through the exhaust flue opening. The improvement involves the secondary combustion means for supplying many jets of secondary air into the flue gases adjacent to the combustion chamber together with a laterally elongated, secondary combustion device having a constriction effect on the flue gases and a large volume secondary combustion plenum chamber with the combustion device and plenum chamber connected in series between the combustion chamber and the exhaust flue opening. The secondary air is provided by a laterally extending manifold with openings producing many distinct secondary air jets extending into the flue gases.
