Over the years, the growing demand for new and improved energy sources has given rise to various fuel forms, one of which is pellet fuels. Pellet fuels, or commonly referred to as pellets are biofuels that are made from the compressed organic matter or biomass. These fuels are derived from the 5 major categories of biomass namely agricultural residues, food wastes, energy crops, industrial wastes and co products as well as virgin lumber. Wood pellets happen to be the most commonly used type of these fuels. They are manufactured by a wood pelletizer, and shall be the focus of this article.

Turn Biomass Wastes into Fuel Pellets

Wood pellets are made from compacted sawdust as well as the related industrial wastes that result from the milling of lumber, the manufacture of wood products such as furniture making and in construction. There are other industrial wastes that could act as raw materials for the manufacture of wood pellets, which include palm kernel shells, tree tops and branches discarded during logging, coconut shells among many more. Maybe you are also interested in pelletizing combustible garbage.

Categories and Functions of Wood Pellets

Wood pellets are categorized using the three variables namely; dimensions, ash and moisture content and heating value.

Depending on their heating value, they could be used as fuels for commercial and residential heating, power generation and even cooking. The production of wood pellets ensures that the moisture content is kept at a bare minimum so that the combustion process can be more profound. (Read more: Benefits Of Wood Pelletising Machine)

Additionally, the pellets are manufactured in regular geometrical shapes and in small sizes for ease of feeding into burners, pellet stoves and any other heating appliances. They are either fed into the burners by auger or through pneumatic conveying. Our wood pelletizer ensure the end pellets are of high density for ease of transportation and storage.

The Pelletizing Process

Wood pellets are manufactured by use of a wood pelletizer. Before the wood material is introduced into the pellet mill, it is first passed through a hammer mill in order to provide a uniform dough-like mass. It is this mass that is fed to a press and squeezed through a die designed according to the desired size. A standard size would normally range between 6mm and 8mm diameter.

The pelletizer operates at a very high pressure and this pressure causes an exponential increase in the temperature of the wood, which result in a slight plasticizing of the lignin. The end result is a natural glue-like substance that holds the pellets together as it is taken through the cooling process.

Quality Standards of Wood Pellets

granulate high quality wood pelletsIt is important to note that there are certain standards used to gauge the quality of wood pellets and while these standards may vary by region, a good quality wood pellet is one generally believed to contain less than 10% moisture content. This allows for complete combustion and reduces the chances of smoking, which could pose serious respiratory and environmental concerns. There should also be uniformity in density and as previously pointed out, this allows for ease of movement and storage. The recommended density is about 0.6 to 0.7 ton per cubic meter. A proper structural strength is also something manufacturers put into consideration when making wood pellets. Last but not least, the pellets should contain minimal amount of ash and dust content.

FAQs: ls There A Specific Wood Type Recommended for Pelletization?

One common question asked by many is whether the quality of wood pellet manufactured differ by wood types and the answer is a resounding no. The breaking down of wood fibres by the hammer mill means that any wood type that makes it past the mill will be processed by the wood pelletizer machine to the required standard.
