Single chamber wood stove including gaseous hydrocarbon supply

A method of controlling a wood stove having a single combustion chamber including a primary combustion zone and a secondary combustion zone in direct fluid flow relation with the primary combustion zone comprising igniting a gaseous hydrocarbon fuel supplied from a source outside the stove to the secondary combustion zone while (a) air is supplied to the secondary combustion zone, (b) wood is burning in the primary combustion zone, (c) air from outside the stove is supplied to the primary combustion zone and (d) products of combustion from the wood burning in the primary zone flow directly to the secondary zone so that combustible gas in the secondary zone from the burning wood is ignited by the ignited gaseous fuel.

A wood stove adapted to be responsive to fuel from a gaseous hydrocarbon fuel source outside the stove, the stove comprising a combustion chamber having a primary combustion zone and a secondary combustion zone in direct fluid flow relation with each other, an inlet through a wall of the stove for admitting air from outside the stove into the primary combustion zone where wood is adapted to be loaded and burning, a conduit adapted to be connected to the fuel source for supplying gaseous fuel from the fuel source to the secondary combustion zone, a flow controller for the gaseous fuel in the conduit, means for detecting the presence and absence of ignition of the gaseous fuel flowing from the conduit into the secondary combustion zone, and means responsive to the detecting means for energizing the flow controller to on and off conditions, the combustion chamber being arranged so that gaseous hydrocarbon fuel in the secondary zone and wood in the chamber burn in said chamber, the gaseous hydrocarbon fuel being introduced into the secondary combustion zone in such a manner as to ignite unburned combustible gases leaving the wood being burned in the primary zone.
