 The inclined moving grate system provides for gentile agitation of high moisture and high ash fuels, maximizes combustion efficiencies, and prevents kilnkering. Water cooled chambers below the compartment control the grate temperatures. Distributed primary, secondary, and tertiary air offers complete control of combustion. |
 The BIOTEC design is a feat of engineering that is over 50 years in the making. Many generations of product design and improvement have resulted in a highly automated, efficient, and user-friendly system that makes operating a biomass boiler nearly as simple as running a traditionally fueled system. |
