Barnett, S G

This patent describes a stove including a stove housing having a burning chamber, a bottom wall, side walls, a top wall and an effluent outlet flue. The improvement described here consists of: a domed wall interposed between the burning chamber and the top wall and including a catalyst substantially at the peak of the domed wall, the catalyst being in effluent communication with the flue; the domed wall and side walls comprising a substantially smooth path for an effluent emitted from a burning fuel such that the effluent emitted remains in a substantially combustible gaseous state in the burning chamber as it reaches the top of the domed wall; an air inlet into the burning chamber having a selectively controllable opening at one terminal end exposed to the environment of the stove; and wherein the amount of air entering the burning chamber is selectively controlled by an apparatus comprising: a thermostat attached to the stove; means for defining a thermostat aperture; moveable means for adjusting the effective size of the thermostat aperture; thermal control unit means for detecting changes in the temperature of the stove to which the thermostat is attached and for moving the moveable means for adjusting the effective size of the thermostat aperture as a function of the change in temperature; and, the moveable means, the means for defining a thermostat aperture and the thermal control unit means cooperating to cause the effective area of the thermostat aperture to change by an amount approximately proportional to the square of the change in temperature of the stove, the effective area being increased responsive to a fall in the stove temperature and being decreased responsive to a rise in the stove temperature.
