KRASZKIEWICZ, A., M. KACHEL-JAKUBOWSKA and I. NIEDZIÓŁKA, 2015. Analysis of selected physical and chemical properties of plant biomass of agricultural origin in terms of its energy use. Bulg. J. Agric. Sci., 21: 1295–1299

The paper presents an analysis made for water content, ash and organic matter - combustible, including its elemental composition, the part carbon, hydrogen, oxygen, nitrogen, sulfur and chlorine in plant biomass of agricultural origin. It was also considered to be determined correlations between the physical and chemical parameters in relation to the amount contained in the test material expressed heat combustion in the air-dry state. For the following types of straw with winter wheat, winter triticale varieties Grenado and Fredro, rye, mix cereal and buckwheat were selected. Determination was made in accordance with generally accepted and applied method. The statistical analysis of test results acquired to determine average values, standard deviations, and Pearson correlation coefficients. Also was carried out ANOVA. The significance of differences between means determined using Tukey’s test. The level of significance α = 0.05. The study showed that the selected physical and chemical characteristics of winter triticale straw Grenado two varieties of winter wheat and Fredro, mix cereal, buckwheat and rye in terms of their energy use was beneficial and desirable. This was confirmed also made comparison of results with those presented by other researchers. Nevertheless, for each parameter, there were significant differences between the means of the raw material concerned. Solid biomass of rye straw and cereal mix, due to the high content of combustible ingredients is the raw material for the most favorable parameters for energy use. The wide variation in the elemental composition of organic matter, as well as their impact on the combustion process and exhaust emissions of individual fuels of agricultural origin indicates a need for further research in this area and make them public.
