ABSTRACT:
A low lying horizontal furnace comprising a fireproof enclosure sealed by a top burns solid fuels which are gravity fed through a vertical feed chamber positioned over a feed aperture in the top of the furnace. An exhaust stack is placed over an exhaust aperture spaced away from the feed aperture for venting exhaust gases from the furnace. Elongated fins are fixed to the underside of the top for channeling the exhaust gases from the feed aperture to the exhaust aperture. The horizontal furnace provides a field expedient furnace for cooking and heating for mass populations in that the top can be placed over a shallow pit dug into the ground for combusting solid fuels.
