Burning Wood Pellets

Wood pellet fuel is growing all around the world, through the use of wood pellet burning solutions such as wood pellet stoves and boilers. There are various different types and grades of wood pellets. With the highest quality and most expensive wood pellets being premium wood pellets. There are various different designs and sizes of pellet stoves and boilers. Pellet stoves can be used purely as room heaters, or with the combination of a back boiler can be used to provide heat to the central heating system. Pellet boilers are generally used on larger properties, and the boiler is less of centre piece than a pellet stove. The video below is of our pellet boiler here at PelHeat, burning a collection of different biomass pellets.

Not all pellet stoves and boilers can burn such a wide range of biomass fuel pellets. The design of the pellet boiler at PelHeat gives it the ability to be flexible enough to use high ash content and clinker fuels, and also withstand the corrosion that some biomass fuels can generate. To learn more about which designs of stoves and boilers can utilize such a wide range of pellet fuels, please visit the Wood Pellet Boiler Guide.

Pellet Fuel

Pellet fuel can be made from various different biomass materials, and each material has different combustion characteristics. For example wood pellets and particularly premium pellets generate very little ash. However other pellet fuel such as straw or grass pellets generate more issues. These issues can be a higher ash content, possible clinker and slag formation, and high temperature corrosion risks. The exception to the rule is hemp pellets. Hemp can be used to produce textiles such as clothes and rope, it can also be used to produce plastics, paper and building materials as well as being a food product. The residue which cannot be processed is ideal for fuel pellet production, as the pellets are low ash.

Wood Pellet Press

A wood pellet press is used to form the wood into pellets. Inside the wood pellet press there is a roller and die set-up. Through a combination of heat and force, the wood is melted and reformed into a pellet shape. When the wood pellets leave the press they are very hot and soft, once the pellets have cooled they are hard, and have a surface shine. A wood pellet press is also know by a wood pellet mill or a wood pellet machine, they all describe the same piece of equipment, however there are different designs available, namely flat die pellet mill and ring designs.
