A control system for a solid fuel combustion appliance, e.g., a wood burning stove, includes a temperature sensor for sensing an output temperature of the appliance. A controller receives the output temperature and controls a damper associated with air flow through the stove to maintain a predetermined temperature. The system also includes a detector that senses certain conditions of the solid fuel, e.g., wood, that is burned by the stove. When additional fuel is added to the appliance, the system temporarily encourages initial combustion of the new fuel, before returning to maintaining the predetermined temperature.

A non-bypassable catalyst assisted appliance includes, for example, a housing having a combustion chamber, a loading door, an air inlet opening, and an exit opening connectable to a flue. A platform defines a non-movable separation in the housing between the combustion chamber and the exit opening. An insulated catalyst combustor is disposed between a top wall of the housing and the platform. When the door of the appliance is closed, gas from the combustion chamber is exhausted and directed along a single flow path horizontally through the insulated catalytic combustor and into the flue. When the door of the appliance is open, gas from the combustion chamber is inhibited from passing through the loading door opening, and ambient air entering the loading door opening and combustion gas from the combustion chamber are exhausted and directed along a single flow path horizontally through the insulated catalytic combustor and into the flue.

Techniques for controlling a solid fuel combustion appliance, e.g., a wood burning stove, are disclosed. A control system measures an exhaust gas temperature of airflow through an outlet of the solid fuel combustion appliance. The control system determines a derivative of the exhaust gas temperature with respect to time. The derivative of the exhaust gas temperature with respect to time is compared to a predetermined threshold. The control system modulates the inlet damper in response to determining that the derivative of the exhaust gas temperature with respect to time reaches the predetermined threshold.

A non-bypassable catalyst assisted appliance includes, for example, a housing having a combustion chamber therein. The housing has a loading door opening coverable by a door for loading fuel into the combustion chamber, an air inlet opening for receiving an air supply to the combustion chamber, and an exit opening connectable to a flue. A catalyst combustor is disposed between the combustion chamber and the exit opening. When the door of the non-bypassable catalyst assisted appliance is disposed in a closed position covering the loading door opening, gas from the combustion chamber is directed through the catalyst combustor, and out the flue. When the door of the non-bypassable catalyst assisted appliance is disposed in an open position allowing loading of fuel through the loading door opening to the combustion chamber, ambient air entering the loading door opening and gas from the combustion chamber are directed through the catalyst combustor, and out the flue.
