Abstract
Stove for burning solid fuels, particularly wood. The stove has a pedestal which has a primary air inlet and an ash drawer; an upright rectangular main housing which is divided internally into a fire box section and a section for combustion products; a housing for electrical components on the back of the main housing; and a flue. The partition between the fire box and the top portion has a first passageway with a catalyst therein and a damper-controlled bypass passageway. Primary air is admitted beneath the grate and passes upwardly therethrough. Secondary air is admitted to the fire box near the glass-panelled charging doors for solid fuel. The stove has a catalyst chamber for completing combustion of the incompletely burned gases in the fire box. A substantially uniform fire box temperature and fuel combustion rate are maintained, regardless of the amount of fuel in the stove (unless fuel is nearly out) by means of a thermocouple in the fire box and an electronic control instrument which controls a valve for admission of primary air. Secondary air is admitted full time although the rate can be varied.
