The sulfur (S) content, nitrogen (N) content, and silicon (Si) content of wood pellets can vary depending on the type of wood used and the production process. However, in general, wood pellets have very low levels of these elements.

Sulfur content in wood pellets is typically less than 0.1%, and nitrogen content is typically less than 0.5%. These low levels are beneficial for combustion efficiency and for reducing emissions of sulfur oxides and nitrogen oxides during combustion.

Silicon content in wood pellets is also typically low, usually less than 1%. However, some species of wood, such as bamboo, can have higher levels of silicon. Silicon can contribute to ash formation during combustion, but it can also have benefits for reducing emissions of certain pollutants.

It’s important to note that the precise S, N, and Si content of wood pellets can vary depending on the source and production process. Therefore, it’s recommended to consult with the manufacturer or supplier of the wood pellets for specific information about the elemental content of their product.
