“Smokeless” Wood Burners Imported From Europe
Dean Zook of Smokeless Heat, a distributor of high efficiency wood burners imported from Europe, says, “By combining a modern gasification burner with thermal water storage tanks, sometimes called “water batteries” you can produce clean heat efficiently and economically without smoke.”
  Smokeless Heat is the North American importer for Varmebaronen boilers. They feature high efficiency wood gasification boilers including models that operate via natural draft, induced draft and computer Lambda controlled. The Viking Bio jet blast pellet burner and boiler combo complete the Varmebaronen product line. The company also sells the Chipmunk 300K BTU small commercial chip/pellet heating systems made near their location in Pennsylvania.
  The key to smokeless technology is gasification, which is a chemical reaction that occurs at temperatures around 700 degrees F between the wood and limited amounts of oxygen. In this environment the gases in the wood release in the form of carbon monoxide, hydrogen and carbon dioxide. The wood gas mixture along with just the right amount of extra air is introduced in the combustion tunnel. This allows these gasses to burn at temperatures approaching 2,000 degrees F. After this mixture is burned, the hot flue gasses transfer into the water thru a very unique exchanger design inside the boiler body. Any left over emissions, mostly water vapor exhaust up the chimney. The pleasant side effect of effective gasification is little or no smoke leaving the chimney. The hot water continues into the storage tank where it is held until a heat demand calls. The water storage allows the boiler to run at full output with no need for inefficient idling found on non storage systems.
  “‘Smokeless’ wood boilers fully use the energy in wood or biomass products with an efficiency two times greater than traditional single chamber firewood boilers,” Zook says.
  Heat generated by the boilers can be integrated into any hot water heating system or a forced air system using a heat exchanger.
  Unlike the good old days when stoking or re-loading the fire in the middle of the night was a common occurrence, these modern boilers can easily be sized to give 8 to 24 hrs. on one fuel load. Prices for the firewood boilers range from about $6,500 for the smallest size up to $12,000 for the largest units plus the costs of the water storage tanks.
  “Varmebaronen boilers are very efficient and reliable,” Zook says. “Any high wear combustion tunnel parts are made to be consumable and are easily owner replaceable.” “A closer look at this unique boiler design will show why it is so easy to clean and maintain.”
