Biomass as a raw material for energy production



Tsatiris Michael and Kyriaki Kitikidou

Abstract
In this paper, the meaning of biomass is defined and it is explained why it is a potential source of energy. The utilization of biomass as an energy source is based on heat energy production during its combustion. The solar energy captured and stored by plants is released in the form of heat energy during the biomass combustion. The variables that affect the energy value (calorific value) of forest biomass involve the chemical composition, percentage of extractives, moisture content, ash content and density. Softwoods generally contain more energy than hardwoods on a dry weight basis, due to higher lignin content plus the presence of more resinous extractives. Lastly, the advantages and disadvantages of biomass as an energy source are analyzed: biomass is renewable and eco-friendly, but its efficiency is low.


Keywords
