Abstract

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.
