ABSTRACT:
A single chamber wood stove has primary and secondary combustion zones in direct fluid flow communication with each other. Air from outside the stove is supplied to the primary and secondary combustion zones. Gaseous hydrocarbon fuel from a source located outside the stove is selectively supplied to the secondary combustion zone and is ignited by a glow plug in the secondary combustion zone in response to a signal derived by a temperature detector in the secondary zone. The gaseous hydrocarbon fuel flows to the secondary combustion zone at a rate in the range of about 0.25 to 3 cubic feet per hour. The fuel is supplied to the secondary zone when the secondary zone temperature is above carbon monoxide ignition temperature.
