Thermogravimetric and Kinetic Study of Fuel Pellets From Biomass of Heracleum Sosnowskyi Manden

Abstract

The comprehensive study of the process of thermal decomposition of fuel pellets from Heracleum Sosnowskyi biomass was carried out. Kinetic parameters of the process were determined based on thermo-gravimetric analysis in comparison with a sample of wood pellets from coniferous wood. The biomass of heracleum Sosnowskyi was collected in the village of Vylgort, Komi Republic, dried to atmospheric-dry state, ground to mean diameter dm<0.25 mm. The elemental composition, the content of the main components, the value of the thermal effect of the initial plant raw materials are determined. The features of the thermal decomposition of samples are established. Kinetic studies of samples pressed at 10 kN were carried out in air environment at heating rate of 5, 10 and 15 °C/min in the temperature range from 25 to 1000 °C using differential methods of Friedman and Ozawa-Flyn-Wall. Comparative analysis of softwood pellets and fuel pellets of hogweed Sosnowskyi confirmed the possibility of using the latter as an independent energy fuel, and as an additive to pellets without significantly reducing their quality characteristics. The results of the presented studies can be used to develop technology and equipment for burning fuel pellets for the purpose of rational extraction of thermal energy.

Invasion of the Giant Hogweed and the Sosnowsky’s Hogweed as a Multidisciplinary Problem with Unknown Future—A Review

“…Caucasian hogweeds showed the enormous ability of regeneration [230]. Their large biomass has resulted in several studies of its use as a biofuel [231][232][233][234]. Secondly, the success of invaders was determined by their enormous reproductive abilities, where propagation was exclusively by seeds.…”

Acetylation of Heracleum sosnowskyi Manden as a local control method to prevent its expansion

“…When slanting, the sap containing furanocoumarins fall on the skin and can cause painful photo-burns from any source of ultraviolet radiation [2]. When burning thickets of Heracleum sosnowskyi Manden there are problems related to prolonged smouldering of this plant, and its failure to maintain an open flame when burning [3,4]. This plant is considered to have no natural pests, and the role of moth caterpillars and elephant beetle larvae is not significant in controlling the plant expansion [5].…”
