A catalytic stove comprised of a housing having a fuel burning chamber and an effluent chamber separated by a domed common wall. An air inlet port is located in the fuel burning chamber and draft air is introduced to burning fuel through an apertured thermal control unit which detects changes in stove temperature. A closure flap is rotatable across the aperture. The thermal control unit, the flap and the aperture cooperate to ensure that the effective area of the aperture changes by an amount approximately proportional to the square of the magnitude of any change in the stove temperature detected by the thermal control unit. Effluent from the fuel flows substantially directly and smoothly from the fuel to a finned holder at the top of the domed wall. The fins then create turbulence in the combustible gases emanating from the burning fuel. The holder supports a secondary air introduction ring which uniformly introduces preheated secondary air to the combustible gases through a plurality of ports thus forming a substantially homogeneous mixture of gases which are then delivered to a catalyst above the dome.

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