Wood Gasification

Regular fire burns at temperatures of 395F to 535F releasing gases from the wood. These gasses are known as synthesis gas or syngas. Syngases are found to contain 50%-80% heat content from wood. Traditional furnaces allow these syngas to escape. Wood gasification captures these gasses producing highly efficient smoke free combustion and low emissions.

Benefits -

  • Flexible, reliable and clean
  • Reduces our dependance on foreign oil and natural gas.
  • Renewable resource
  • Environmental benefits with fewer emissions

 How the RS7400E Works -

  • Firebox- Drum air tubes blow air into the firebox forcing the syngas down into the secondary burn chamber.
  • Secondary Burn Chamber - Ceramic fiber lined chamber collects heat from above fire and absorbs the syngas then burns them at temperatures as high as 2000F. 
  • Heat Transfer Tubes - Exhaust air escapes through the heat transfer tubes running throughout the water jacket, heating the water to desired temperature.
  • Chimney - Exhaust air escapes out the chimney which has cooled to temperatures of 300F by the time it exits the chimney.
