Generated explanation

A cross-section of a wood furnace shows a lower primary combustion chamber containing burning logs and an upper secondary combustion chamber. Separate arrows indicate primary combustion air entering the firebox and secondary combustion air entering above the fuel. A baffle separates portions of the combustion path, with exhaust flowing through the upper chamber and into a flue connector on the right. A belt-driven blower circulates cold return air through the furnace, while heated supply air exits through the duct on the upper left. The illustration explains the two-chamber arrangement without depicting a defect.
