How To Choose Biomass Pellet Fuel?

Raw material source High-quality biomass pellet fuel should be made of pure and single raw materials. Common raw materials include wood chips, straw, rice husks, etc if the source of raw materials is complex. Wood pellets: Made from wood processing residues, with high combustion calorific value and less ash, they are an ideal biomass pellet fuel. Straw pellets: Made from crop straw, the cost is relatively low, but the ash content may be slightly higher. Rice husk pellets: With a certain hardness, it is relatively stable when burning, but the calorific value may be slightly lower than wood chip pellets. Pellet quality The appearance should be cylindrical, uniform in length, smooth on the surface, and without cracks and impurities, brown or light yellow is preferred, otherwise the production process may be poor or there may be problems with the raw materials. The high density has a long combustion time and high calorific value, which can be calculated by measuring weight and volume. Generally, the quality is better at 1.0 - 1.3g/cm³. High hardness is not easy to break, easy to store and transport, can be felt by hand, easy to break will produce powder during transportation, affecting the combustion effect.
