Title
(EN) SOLID FUEL HEATING APPLIANCES
Abstract
(EN)
The heating appliance includes an insulated secondary combustion chamber (22, 110) where a mixture of exhaust gases from the primary combustion chamber (12, 112) and secondary air is burned. A catalytic igniter (34, 130) is provided in the secondary combustion chamber. In a retrofit embodiment (115) for existing stoves, a sheet metal partition (122) in the secondary combustion chamber allows heat transfer from spent gases to the entering mixture of exhaust and secondary air. In a unitary stove embodiment (10), secondary air is heated by the spent gases which proceed to remote heat exchangers (48) separated from the primary firebox by ventilated air spaces (50). The combination of the insulated secondary combustion chamber, catalytic igniter, and the regenerative heat transfer assure substantially continuous combustion within the secondary combustion chamber even when conditions in the primary combustion chamber change. To prevent room emissions, the stove door is sealed by a vented double gasket system (62, 64).
