Wood pellets are a kind of green energy made from sawdust and crop stalks. Wood pellets have high combustion efficiency and low pollution, and are replacing coal as the main fuel for industrial manufacturing. Due to the wide variety of wood pellet products, how to choose the right wood pellet seems to be an important matter. Below, we’ll give you some advice on it.
Ash content
First, you should check the ash content of the wood pellets. Excellent wood pellets have a lower ash content. Statistics have proved that wood chips made of pine, beech, polar and other softwoods have less ash and high combustion efficiency.
Size
Moisture content
Third, you should find out the moisture content of the wood pellets. According to tests, wood pellets with a moisture content of more than 10 to 15 percent burn unevenly. So when choosing wood pellets, the lower the moisture content, the higher the quality of the wood pellets.
Energy density
Fourth, you should look for the energy density or calorific value of the wood pellets. Wood pellets with high energy density and calorific value release more energy and burn longer.
Origin
Finally, attention should also be paid to the origin of the wood pellets. Due to the addition of some additives to some wood pellets, the quality of wood pellets will be affected. So when buying wood pellets, you should check what the wood pellets are made of and whether any additives have been added.
