Abstract
A hot air heat exchanger furnace that uses crop residue as a fuel source is provided for producing the heat required for various purposes, such as the drying of grains, peanuts, soybeans and other materials and for the heating of buildings. The furnace includes a combustion chamber, an upper manifold, a lower manifold, a plenum and a number of exhaust tubes. The exhaust tubes direct the flow of combustion gases from the combustion chamber in a serpentine path in the plenum between the upper and lower manifolds and into a stack. Meanwhile, ambient air passes into the plenum, past the heat transfer surfaces of the combustion chamber and the exhaust tubes as heat transfers to it. Then it passes out of the furnace.
