Biomass pellets Wood pellets Biomass fuel is a columnar environmentally friendly new energy produced by processing straw, straw, rice husks, peanut husks, corn cobs, camellia husks, cottonseed husks, etc. as well as "three residues". The diameter of biomass particles is generally 6-10 mm.

Basic characteristics
Biomass shaped fuel uses agricultural and forestry waste as raw materials, through crushing, mixing, squeezing, drying and other processes, into a variety of shaped (such as block, granular, etc.), a new type of clean fuel that can be directly burned. Biomass shaped fuel, mostly stem-shaped crops, peanut shells, bark, sawdust, and solid waste (furfural residue, edible fungus residue, etc.) block fuel produced after processing, the diameter of biomass pellet fuel is generally 6-10 Mm, the length is 4-5 times its diameter, the crushing rate is less than 1.5%-2.0%, the dry basis moisture content is less than 10%-15%, the ash content is less than 1.5%, the sulfur content and the chlorine content are both less than 0.07%, and the nitrogen content Less than 0.5%. The EU standard does not provide specific values for the calorific value of biomass pellets, but requires sellers to label them. The Swedish standard requires that the heating value of biomass pellets should generally be greater than 16.9 MJ. [2] 
Biomass solid fuel technology
Biomass solid shaped fuel technology is that under the action of a certain temperature and pressure, various types of biomass, such as straws and branches, which are originally dispersed without a certain shape, are dried and crushed, and pressed into a certain shape with a higher density New technologies for various shaped fuels. Its products are rod-shaped, block-shaped and granular shaped fuels with a density of 0.8-1.4 g/cm3 and a calorific value of about 16720 kJ/kg. Its performance is better than wood, equivalent to medium-quality bituminous coal, can be directly burned, and the combustion characteristics are significantly improved; at the same time, it has less black smoke, strong firepower, full combustion, no fly ash, clean and sanitary, nitrogen oxides (NOx), sulfur oxides (SOx) Very small emissions and other advantages, and it is easy to transport and store, becoming a commodity. It can replace coal and burn directly in a boiler to generate electricity or heat. It can also be used to solve basic living energy problems in rural areas.
Production process and equipment editing
The direct burning of straw agricultural solid waste raw materials will emit black smoke, which is not fully burnt, causing pollution to the atmospheric environment. The state allows it to be used as a living fuel in rural areas, but it is not allowed to be used in cities, and the burning of farmland straw is prohibited. Biomass shaped fuel is a new type of clean fuel that uses straw-like agricultural solid waste as raw materials and undergoes crushing, mixing, squeezing, drying and other processes to make shaped fuel such as lumps and pellets, which can be directly burned.
