Gasification Stove "Bakes" Fuel Before Burning

The two biggest concerns with outdoor wood burning stoves and boilers are too much smoke out the stack, and too much wood burned. This new "gasification stove" was designed to solve those problems.
  The patent pending "Blue Forge" gasification stove burns wood, corn, pellets, or hay.
  It got its name from the forge-type fire it creates, caused by an "upside down" burn. The unit smokes less because it burns the emissions coming down from the primary firebox in a secondary burn chamber, where air is injected.
  The furnace was designed by Les Graham, who has worked in the wood boiler industry for 18 years. "This is a gasification unit that produces very little smoke, which is important because the EPA recently came out with a new set of standards to regulate the emissions coming out of outdoor wood boilers."
  In the primary firebox, wood goes through an intense baking process that pulls out the gases and burns them as they're forced down through a coal bed.
  "Any smoke that does remain after going through the coal bed is reignited by the secondary air that's injected in a secondary burn chamber. The chamber is accessible from the front of the stove and doubles as the ash removal area," says Graham.
  "After filling the stove with wood, you can place cardboard, paper or pine needles on top of the wood at the top of the firebox. If you come back anywhere from 12 to 24 hours later, you'll see that the materials still haven't burned. And they won't, until they work their way to the bottom of the stove."
  He says you can burn wood or corn without changing anything. "Most wood burning boilers offer bolt-on kits to convert to corn, but the kit alone can sell for $2,000 or more," says Graham.
  The unit has a modular design, and each component is replaceable. "If you have problems with the stove, you can tear it apart and replace only the parts instead of the entire unit."
  Two models are available. Model 1300 with a 13 cu. ft. firebox sells for $8,200; model 1900 with a 19 cu. ft. firebox sells for $9,200.
  The unit comes with a pump, pump flanges, aquastats, draft fan, expansion tank, scoop, vent, insulation wrap, and a forced air coil that can be installed in the plenum of a forced air furnace. For floor heating, Graham imports tubing from Belgium that's unique to the industry.
