Description
The Eko WOOD boiler is responsible for gasifying wood gas, which is burned in it. This device uses the PYROLYSIS process – it burns gases that arise as a result of the thermal decomposition of wood with a small amount of oxygen. Eko Wood is a gasifying boiler that is most efficient when burning wood with a moisture content of 12 – 20%.
