The calorific value of biomass pellet fuel is about 3900-4800 kcal/kg, and the calorific value of standard coal is 7000 kcal/kg.
Comparing the two, it is obvious that standard coal has a higher calorific value.
Biomass pellets use biomass pellet machine to process crop straw, wood chips, municipal solid waste, construction waste and other raw materials by crushing, drying, pelletizing, cooling and other processes to produce a pellet that can replace coal. Renewable biomass energy that can be used as fuel has the advantage of near-zero sulfur dioxide emissions and regenerations, and is favored by cities that ban coal.
1. Suitable for all stoves, suitable for rural areas, cities, units and families. It is an ideal fuel for ckitchen, heating, bathing, boilers and straw power plants; 2, the particles are small and hard, easy to place and distribute. It is a good fuel for pottery firing, brick and tile factories, and the smelting and chemical industries
3. particles) coal is rich in containing calcium, magnesium, phosphorus, potassium, sodium and other elements, it is a good fast-acting thermal organic fertilizer. In addition, after processing the ash, the extracted nano-silica and iron trioxide are also popular in the market.
According to Swedish and European standards for classification of biomass particles, if its intermediate classification value is used as an example, biomass particles can be roughly described as having the following characteristics: The particle diameter of biomass is generally 6~8mm, the length is 4-5 times its diameter, the breakage rate is less than 1.5%~2.0%, the dry base moisture content is less than 10%~15%, the ash content is less than 1.5%, the Sulfur and chlorine content are both less than 0.07%, nitrogen content is less than 0.5%.
If additives are used, they must be agricultural and forestry products, and the type and quantity used must be indicated. The European standard does not propose a specific value for the calorific value of biomass pellets, but requires sellers to label it.
