Biomass boilers work by burning biological matter and outputting the resulting heat for use in heating systems. Wood pellets, chips, logs or other biological materials are fed – automatically, semi-automatically, or by hand – into a combustion chamber where they are ignited.
How does a wood chip burner work?
How do wood pellet boilers work? The boiler auger feeds wood pellets directly into the burner where they are ignited, and the heat generated is automatically controlled by the feed rate of pellets. A fan in the boiler propels hot gas into the boiler primary heat exchanger.
What fuel does a biomass boiler use?
Wood Pellets: Made from compacted sawdust, woodwork/forestry waste or wood shavings, wood pellets are the most frequently used fuel for domestic biomass boilers.
