Analysis of the Combustion Process of Selected Wood Biomass

Combustion process of selected woody biomass was investigated. Four types of woody material were used for conducted experiments: poplar, pine, acacia and willow. European Union policy concerning Renewable Energy Resources (RE) is a response to increasing pollution of our globe, and, simultaneously, it introduces additional, independent supplies of energy. With the introduction of legal obligations that regulate these norms, countries that did not have appropriate percentage share of renewable energy had to comply with these regulations by implementing appropriate projects that would allow for supplies of renewable energy shortly. The work presents ecological aspect of selected materials, by showing differences in fuels obtained from woody biomass used in the experiments. It was analyzed the ash and volatile matter content and also calorific value. The experiments also show, which dendromass has the best energetics parameters, and which produces the least pollution. Poplar had the highest net calorific value (18,633 J/g), but during poplar combustion, the highest concentration of carbon oxides and nitrogen oxides was found.
