Catalytic combustion assembly for wood-burning stove
A catalytic combustor is described for a wood-burning stove. The stove includes a flue outlet and a firebox having a ceiling and a primary air inlet for supplying primary air to the firebox. The assembly consists of: an insertable housing having a pair of spaced-apart parallel walls having tops, the walls defining an airtight passageway for volatile gases from the firebox to the outlet; a catalytic combustor mounted within the housing across the passageway to intercept the volatile cases and burn them with the secondary air; a bypass door pivotally mounted to a base of the housing for opening and closing a bypass opening in the base; a mixing screen sealingly mounted within the housing across the defined passageway upstream of the catalytic combustor, the screen having holes to promote mixing of the secondary air released from the transverse conduit and the volatile gases from the firebox; and an inclined baffle mounted within the housing across the passageway downstream of the catalytic combustor for impeding the gas flow therethrough to increase the residency time of the gases within the catalytic combustor and thereby promote a cleaner burn, the baffle positioned below the flue outlet and including an upturned tip portion for guiding the gas flow into the outlet.
