The main advantages of biomass pellet fuel relative to coal are environmental protection, regeneration and waste utilization, these advantages are well-known and conventional. The advantages of biomass fuel pellets can be deeply understood through the composition of biomass pellet fuel, along with the combination and characteristics of various elements.
Biomass pellet fuel is composed of combustible substance , inorganic substance and water. It contains carbon (C), hydrogen (H), oxygen (O) and a small amount of nitrogen (N), sulfur (S), etc., and contains ash and moisture.
Biomass forming fuels are low carbon fuels with a low carbon content (about 45-50%), especially low fixed carbon content (about 16%), so carbon emissions are low when burned.
Biomass pellet fuel contains a lot of hydrogen (about 5-8%), and the volatile component is high ( more than 70%), so the combustion characteristics are good.
Biomass pellet fuel has a high oxygen content (about 35-40%). Biomass fuels significantly have more oxygen than mineral coal, which makes biomass fuels easy to ignite.
The sulfur content in the biomass pellet fuel is less than 0.08%, and the environmental protection feature is good, and the flue gas desulfurization device is not necessary when burning.
High quality wood is mainly used as raw material of biomass pellet fuel, and ash content is low, only 1.5-3%.
Calorific value is an important index of fuel quality, which is the heat emitted by the complete combustion of fuel per unit mass (or volume). The calorific value of biomass fuel pellet is 15-18 MJ / Kg, and about 2 -3 kg BMF may replace 1 kg fuel oil or 1 cubic natural gas.
In addition, the harmful gases produced when biomass pellet are burned are extremely low, and has environmental protection benefits. And the ash after burning can also be used as potash fertilizer directly, saving expenses. As a new kind of pellet fuel, biomass pellet has been widely recognized for its unique advantages. Compared with traditional fuel, not only has economic advantages but also environmental benefits, which fully meet the requirements of sustainable development.
