How Wood Pellets Are Made

May 24, 2019

       Biomass fuel is mostly block new environmentally friendly energy source processed by stem-shaped crops. Its diameter is generally 6~8 cm, its length is 4~5 times its diameter, the breaking rate is less than 1.5%~2.0%, and the dry water content is dry. It is less than 10%~15%, the ash content is less than 1.5%, the sulfur content and chlorine content are less than 0.07%, and the nitrogen content is less than 0.5%. If additives are used, they should be agricultural and forestry products and should indicate the type and amount of use. The EU standard does not provide specific values for the calorific value of biomass fuel, but requires the seller to indicate it. The Swedish standard requires that the calorific value of biomass fuels should generally be at 16.9 MJ.

     Biomass liquid fuels include biomass alcohol (ethanol), biodiesel and biomass fuel oil: material ethanol mainly consists of carbon, hydrogen and oxygen; biodiesel is mainly composed of carbon, hydrogen and oxygen; biomass fuel oil Mainly composed of carbon, hydrogen, oxygen and other elements.


      Different fuels produce different calorific values, such as wood pellets calorific value: 4300-4800 kcal, corn straw pellet calorific value: 3500-3800 kcal, after compression is relatively resistant to burning, fuel is smoke, is Depending on the manufacturing process of the combustion equipment, the combustion equipment manufacturing process is reasonable, the combustion is sufficient, and basically no smoke is emitted, and instead smoke is generated. The straw can be cut to a length of 1 cm to produce granules with a density of 1.1 without special formulation.

      Biomass gas fuels are mainly carbon monoxide, hydrogen, methane, unsaturated hydrocarbons and non-combustible components such as carbon dioxide and nitrogen. Therefore, elements are composed of carbon, hydrogen, oxygen, nitrogen and other elements. Will burning biomass fuels increase greenhouse gases?

      Burning biomass fuel does not increase greenhouse gases!

      Because biomass fuel consumes CO2 during the production process, it just offsets the CO2 produced during the combustion process. It is somewhat different for fossil fuels. Although the process of production also consumes CO2 and produces O2, the O2 produced is long. Years have become part of the Earth's atmospheric environment, and humans and other modern creatures have adapted to this environment. If these fossil fuels are now mined and burned, it is bound to return the atmospheric environment to ancient times.
