Low emission stove
A low emission fuel-burning stove is described comprising: a firebox having bottom, side and top walls for initiating primary combustion of fuel placed at a fuel level within the firebox; a baffle means dividing the firebox vertically into a large volume lower primary combustion chamber and a substantially smaller volume upper secondary combustion chamber; primary air inlet means in multiple sidewalls of the firebox at substantially the fuel level for injecting primary combustion air into the firebox at substantially fuel level; second air inlet means in multiple sidewalls of the firebox substantially above the fuel level; third air inlet means in the bottom of the firebox; secondary combustion air inlet means above the second air inlet means at a fourth level within the firebox to supply air for secondary combustion within the secondary chamber; the baffle means defining with its downturned free end portion and a sidewall a restrictive passage connecting the primary chamber to the secondary chamber for receiving combustion products discharged from the primary chamber and conveying them to the secondary chamber.
