Title
(EN) Woodburning heating apparatus
Abstract
(EN)

Woodburning heating apparatus including a catalytic igniter for increasing heating efficiency and reducing polluting emissions. The apparatus includes a secondary combustion chamber in gaseous communication with a primary combusiton chamber. The secondary combustion chamber is lined with a refractory material and includes a perforate catalytic igniter through which combustion gases from the primary combustion chamber flow. The secondary combustion chamber further includes refractory baffles arranged to enhance mixing of the combustion gases and located to re-radiate heat onto the catalytic igniter. Preheated secondary combustion air enters the secondary combustion chamber so that the combustion gases are more completely burned to improve heating efficiency and reduce emissions.
