One of the biomass fuels—biomass pellet fuels, which are mainly processed from pure wood raw materials, are generally discarded sawdust, sawdust, shavings, etc., do not add any adhesives and additives during processing, and use professional students. Material forming equipment is processed, compressed into rods with a diameter of 8-10 mm and a length of 30-50 mm. Through such processing, the density, strength, and combustion properties of the raw materials are changed to change the density, and the bulk material is “tight and seamless”, which can suppress the volatilization and overflow rate of the product and allow the fuel to burn to the fullest extent possible.
Biomass energy is a renewable energy source. Among alternative energy sources for burning coal, the price is the most economical, the most widely distributed, and the biomass density is small (8-10 cubic meters per ton). After being manufactured into granules, the density can reach 0.9- 1.15 tons/cubic meter not only greatly reduces the volume, but also facilitates transportation, and avoids the sun, wind, rain, and especially the erosion of mold and other rotten bacteria after granulation. Therefore, the biomass energy is made into the biomass fuel market. The prospects are very broad
How the environmental protection of biomass pellet is mainly reflected in the following aspects:
1. Biomass-fired coal-fired coal replaces conventional energy such as coal, fuel, and gas, which can effectively reduce the emission of atmospheric pollutants such as carbon dioxide, sulfur dioxide, and nitrogen dioxide, and effectively improve the quality of urban and rural air environment. The content of sulfur in biomass particles is less than 1/10 of that of coal, and its alternative coal combustion can effectively reduce the emission of sulfur dioxide in the atmosphere; the CO2 emitted by biomass during combustion and its absorption during photosynthesis in the growth process As much as the net emission of CO2 from biomass combustion to air is zero from a recycling perspective. They say that biomass fuels are environmentally friendly. Let's use numbers to explain
2. Combustible ash can be comprehensively utilized after biomass combustion. The ash can be recovered as potash fertilizer and achieve effective circulation of “straw-fuel-fertilizer”.
3. To properly dispose of abandoned crops and reduce the impact on the environment: In terms of straw alone, China's annual crop straw production weight is approximately 706 million tons. If straw crops and other abandoned crops are naturally rotted, large amounts of methane will be produced. It is generally believed that the greenhouse effect of methane gas is 21 times that of carbon dioxide. The use of waste crops as fuel not only turns waste into treasure, saves resources, but also reduces greenhouse gases and protects the environment.
