How To Define “Qualified” Biomass Pellets?

In the pellet fuel market of Europe and USA, there exists several industrial standards. If you are going to sell your pellet products to the market there, then you should study their standards in advance. Otherwise, your products may be unwelcomed for not meeting their standard. However, in a general sense, the quality of the pellets are often judged on two aspects–mechanical durability and moisture content.

Mechanical Durability
Mechanical durability refers to the density of the pellets. The more dense the pellets are, the more solid it is with low ash content. In that case, they can better withstand the crash during the transportation and have a high combustion efficiency in the pellet stove or boiler. Furthermore, we can also tell the quality of the pellets from its surface. Usually speaking, the granulated pellets should have a smooth surface like a crayon with little or no cracks.

Moisture Content
Since the moisture content is low in the biomass pellet, it can release energy more efficiently when burning. However, no moisture at all in the biomass pellet is wrong. Our goal is to keep the moisture content at about 10% in the end products.

No matter you are producing biomass pellets for your own use or for selling, there are still some rules you can follow to make high-quality pellets.
