Traeger wood pellets
Wood Pellets near me (or pellets) are biofuels made from compressed organic matter or biomass. Pellets can be made from any one of five general categories of biomass:
In addition, industrial waste and co-products, food waste, agricultural residues, energy crops, and untreated lumber.
More over, Wood pellets are the most common type of pellet fuel and are generally made from compacted sawdust and related industrial wastes from the milling of lumber, manufacture of wood products and furniture, and construction. wood pellets near me

Other industrial waste sources include empty fruit bunches, palm kernel shells, coconut shells, and tree tops and branches discarded during logging operations.
So-called “black pellets” are made of biomass, refined to resemble hard coal and were developed to be used in existing coal-fired power plants. Pellets are categorized by their heating value, moisture and ash content, and dimensions.
Pellets are extremely dense and can be produced with a low moisture content (below 10%) that allows them to be burned with a very high combustion efficiency.
Further, their regular geometry and small size allow automatic feeding with very fine calibration. They can be fed to a burner by auger feeding or by pneumatic conveying.

Their high density also permits compact storage and transport over long distance. They can be conveniently blown from a tanker to a storage bunker or silo on a customer’s premises.
In a 2012 report, the Biomass Energy Resource Center says that it expects wood pellet production in North America to double again in the next five years.

Furthermore, The high pressure of the press causes the temperature of the wood to increase greatly, and the lignin plasticizes slightly, forming a natural “glue” that holds the pellet together as it cools.
Where to buy Wood Pellets
In addition, Pellets can be made from grass and other non-woody forms of biomass that do not contain lignin.
In 2012, the Department of Agriculture of Nova Scotia announced as a demonstration project conversion of an oil-fired boiler to grass pellets at a research facility.
Rice-husk fuel-pellets are made by compacting rice-husk obtained as by-product of rice-growing from the fields. It also has similar characteristics to the wood-pellets and more environment-friendly, as the raw material is a waste-product.

The energy content is about 4-4.2 kcal/kg and moisture content is typically less than 10%. wood pellets near me
The size of pellets is generally kept to be about 6 mm diameter and 25 mm length in the form of a cylinder; though larger cylinder or briquette forms are not uncommon.
More to that, An environmental impact assessment of exported wood pellets by the Department of Chemical and Mineral Engineering, University of Bologna, Italy and the Clean Energy Research Centre, at the University of British Columbia, published in 2009,
Pellet standards :
Firstly, Pellets conforming to the norms commonly used in Europe (DIN 51731 or Ö-Norm M-7135) have less than 10% water content, are uniform in density (higher than 1 ton per cubic meter, thus it sinks in water)(bulk density about 0.6-0.7 ton per cubic meter), have good structural strength, and low dust and ash content.
Pellets can be made from nearly any wood variety, provided the pellet press is equipped with good instrumentation. wood pellets near me
In Europe, the main production areas are located in south Scandinavia, Finland, Central Europe, Austria, and the Baltic countries.
Also, Pellets conforming to the European standards norms which contain recycled wood or outside contaminants are considered Class B pellets.
Regulatory agencies in Europe and North America are in the process of tightening the emissions standards for all forms of wood heat, including wood pellets and pellet stoves. wood pellets near me
Furthermore, These standards will become mandatory, with independently certified testing to ensure compliance.
The American Lumber Standard Committee will be the independent certification agency for the new pellet standards. wood pellets near me
