ABSTRACT:
Exterior retrofit system for attachment to wood or coal-burning stoves including a secondary combustion chamber and a catalytic igniter. The secondary combustion chamber is lined with refractory material and is arranged to preheat flue gases emanating from the woodburning apparatus before ignition at the catalytic igniter. The refractory walls have an undulating structure to increase mixing and residence times for more complete burning. Provisions are made for introducing additional combustion air into the secondary combustion chamber. Combustion performance is improved resulting in reduction of cresote deposits and particulate emissions and reduction in the amount of fuel consumed for a given heat output. The retrofit unit is self-contained and requires no permanent or complicated modification to the stove. This system also has application for use on the interior of a stove, both as a retrofit and as the basis for a specifically designed stove. The resulting improvement in combustion performance would equal or exceed that of the exterior application.
