Abstract: This wood by-pass furnace is designed in such a manner, as to have the oxygen for combustion controlled, to the extent that the wood does not blaze, but only produces red, glowing coals for heating a home, and the outside cover will not burn anyone when touched. It primarily consists of an inside fire chamber of cylindrical shape, to distribute heat to the top, and it includes a top baffle, that extends from the front of the fire chamber, to the rear of the furnace. It further includes two side baffles, to protect the sides of the heat chamber, and smoke and heat travels up and over the top of the top baffle, to the front of the stove or furnace, and passes out an eight inch pipe. The top baffle further serves to condense the black smoke into liquid, which will dry out and will burn in its dry form.
