The research and development of bio-energy technology has become one of the world's major hot topics and has attracted the attention of governments and scientists around the world. Many countries have formulated corresponding development and research plans, of which bio-energy development and utilization account for a considerable share. Many foreign bioenergy technologies and devices have reached the level of commercialization. Compared with other biomass energy technologies, biomass particle fuel technology is easier to achieve large-scale production and use, and its degree of convenience can be comparable to gas, fuel, and other energy sources.
Wood pellet biomass fuel is one of the representatives of modern clean and environmentally friendly energy, and many power plants are using biomass fuels. For biomass fuels, we still need to carefully identify when purchasing. How do we choose good quality wood pellet biomass fuel? Chinese medicine is still "looked and asked to touch", we may also try this method when purchasing biomass pellets!
Observe the pellet color, luster, purity, ash content after combustion, and various types of raw materials. Wood pellets and straw pellets are mostly light yellow and brown. Pureness means granulation, the better the granulation condition, the longer the length, the scrap Less is the finer particles; the less ash content after combustion of the produced particulate fuels, the purer and better quality of the raw materials, the only ash content of the pure wood pellets is only 1%, the least ash content, the ash content of the straw particles is slightly larger, and the ash content of the domestic waste particles. The highest, up to 30%, the most quality, in addition, there are many factories in order to save costs, add lime, talcum powder and other impurities in the particles, after burning, the ash is white; the better the quality of the particles, the higher the gloss.
Because of the smell of pellets, most of the particles still retain the odor of their raw materials because the biomass particles cannot add task additives during the production process. The wood particles have an aroma of wood, and various kinds of straw particles also have unique odor of straw.
Ask the production or supplier for raw materials for pellet production. It is said that pure wood chips are not used to dope other types of sawdust. All kinds of wood sawdust, sawdust, mahogany, and poplar can all be used. Abandoned scraps from furniture factories can also be used. More broadly speaking, like crop stalks or peanut husks, these things can be used as raw materials for wood pellet mills. Of course, granules can not be called wood granules but straw granules.
Touch the pellet by hand to identify the quality of the particles. Hand touch particles, smooth surface, no cracks, no scrap, high hardness, indicating that the quality is good; the surface is not smooth, there are obvious cracks, debris a lot, the hand will be broken pieces of fine quality.
