Use of Biomass as a Raw Material for Energy Production
The purpose of this research is to explain why biomass is used as a raw material for energy generation. The significance of biomass is defined, as well as why it is a potential energy source. The use of biomass as an energy source is based on the creation of heat energy during burning. During biomass burning, the solar energy absorbed and stored by plants is released as heat energy. The chemical composition, percentage of extractives, moisture content, ash content, and density of forest biomass are all factors that influence its energy value (heating value). The literature review stated the calorific values of several chemical components (cellulose, lignin, extractives), forest species (Softwoods, hardwoods), and different portions of the same tree (wood, bark, leaves, branches) as numerical facts. On a dry weight basis, softwoods have more energy than hardwoods due to increased lignin content and the presence of more resinous extractives. Finally, the benefits and drawbacks of biomass as an energy source are discussed: biomass is renewable and environmentally beneficial, but it has a poor efficiency. However, because of rising oil prices and the pollution generated by its combustion, this problem is progressively dissipating, encouraging a greater use of biomass as an energy source.
