1. High resource utilization rate
Agriculture and forestry waste (straw, sawdust, branches, fruit shells, etc.) can be used almost 100% to avoid the transformation chain of "waste-pollutants". For example, about 1 billion tons of straw, if converted into particulate fuel, can replace 200 million tons of standard coal, which is equivalent to reducing 250 million tons of carbon dioxide emissions.
2. Stable energy attributes
The particle shape is regular, which facilitates automatic feeding (adapted to boilers, fireplaces and other equipment);
Low moisture content (usually ≤15%), sufficient combustion, and thermal efficiency can reach more than 80% (far exceeding 30%-40% of direct combustion of bulk materials);
The calorific value is stable (about 15-18MJ/kg), and can be used as a standardized fuel for industrial boilers and civilian heating.
3. Highly environmentally friendly
Carbon cycle balance: Biomass grows and absorbs carbon dioxide, and the CO₂ released during combustion is comparable to the absorption of the growth stage, and hardly increases the atmospheric carbon concentration ("carbon neutrality" characteristic);
Low pollutant emissions: Compared with coal-fired coal, sulfur dioxide emissions when particulate fuels are burned are only 1/10 of that of coal, and nitrogen oxides are about 1/2. Dust can be met through simple filtration and meet environmental protection policies requirements (such as my country's "Boiler Air Pollutant Emission Standards" for biomass fuels).
4. Strong adaptability of the industrial chain
The production process is simple (pulverization → drying → granulation → cooling → packaging), and small and medium-sized production lines (investment 500,000-2 million yuan) can operate, which is suitable for county economic model and can drive rural employment (such as raw material collection and processing links).
Biomass pellet fuel not only solves the problem of waste pollution, but also provides sustainable clean energy, which is especially suitable for the energy structure transformation needs of agricultural powers. Therefore, calling it the "ideal method" is an recognition of its ability to balance in the triple dimensions of resource, energy and environment.
