Smoke-Free Outside Wood Burning Furnace ENERGY Wood Burners (65) 25-6-35 My home-built outside wood burning furnace is designed to burn less wood than conventional furnaces and is virtually smoke-free. It also leaves hardly any ashes. The unit is made of 1/4-in. thick boiler plate and has a stainless steel firebox. It measures 2 ft. wide, 3 ft. high, and 2 ft. deep . It'll heat a 2,000-sq. ft. house at 78 degrees for up to three days during the winter on just one wheelbarrow full of wood. The key component is a tortuous flow box for the smoke that extends up through the unit to the flue on top. It burns with a clean blue flame - a process that's being patented. No catalytic equipment is used. Temperatures in part of the tortuous flow box can reach up to 1,500 degrees, which breaks down the smoke molecules to eliminate smoke. In fact, I can put my nose right over the stack and not smell anything. Gas coming out of the wood gets the proper amount of oxygen which is why the wood burns clean.
I've made both hot water and hot air versions for neighbors. Now I'm looking for a manufacturer. (Elmer Laitinen, 8731 East Monroe Road, Wheeler, Mich. 48662 ph 989 842-1257)
