Biomass, as a fuel has several advantages among which the most important are its availability, renewability and “zero-emission” of CO2. However, apart from several advantages as an energy source material, it has also some disadvantages, among which are [8], [9], [10] and [11]:
-
Relatively low density of raw materials, hindering the transport, storage and dispensing,
-
Wide range of biomass humidity, which makes it difficult to prepare for use for energy purposes,
-
Lower than for fossil fuels energy value of raw material,
-
Variability of fuel properties, resulting from changes in humidity and composition.
