Okotherm Multi-fuel Boilers
The Okotherm Multi-fuel boilers are highly versatile, burning a large range of biomass fuels in chipped or pelletised form. Okotherm boilers are available from 49 kW to 800 kW, they are built to avoid clinkering and slagging with any fuel and can burn cleanly without the need for additices such as lime. They have proven their worth in the German market over the last 20 years and have been burning miscanthus as a reliable crop for the last 17 years. In 2007, the inventor of the Okotherm boilers received the EUROSOLAR prize for his achievments.
