Abstract

The problem of uncontrolled spread of Sosnovsky hogweed is relevant for many subjects of the Russian Federation. Considerable resources are being spent on combating this problem. The use of hogweed in various industries can open up good prospects. One of the possible options for such an application may be the energetic use of hogweed after preliminary drying in natural conditions and crushing in a crusher. However, a more effective direction of its energy use is the combustion of fuel pellets made from its biomass. The purpose of the study is to study the thermal properties of Sosnovsky hogweed, its elemental composition and the composition of ash formed during its combustion. The elemental composition and thermal characteristics of the biomass of Sosnovsky hogweed, as well as its ash, have been studied. As a result of the analysis of the elemental composition of the samples, it was found that the content of oxides of alkaline earth and alkali metals (CaO, Na2O, K2O), which determine the polluting properties of ash, exceeds the limit values by more than 3 times. The lowest heat of combustion per combustible mass is 18,809 MJ/kg, ash content per dry mass is 7.7 %. The results of the study showed that the thermal characteristics of the plant biomass of Sosnovsky hogweed make it possible to consider it as a possible energy fuel, however, the elemental composition of the ash formed during its combustion makes it possible to predict high polluting properties of focal residues
