Pyrolysis and combustion process of biomass fuels by TG–DTA/MS analysis
The thermal behavior of selected 2 species of biomass fuels (Broad-leaved bark and Needle-leaved xylem in) was investigated using a thermogravimetric analyzer (TG-DTA/MS) under the temperature range from room temperature to 1000℃ in the Ar and air atmosphere at 3 heating rates of 10℃, 40℃ and 60℃/min. A kinetic model, involving first-order independent parallel reactions, was applied to results obtained from pyrolysis TGA experiments. The pyrolysis rate was considered as the sum of the main biomass pseudo-components, namely cellulose, hemicellulose and lignin. Additionally, the thermal behavior of the same fuels was investigated at combustion conditions in the TGA. The thermogravimetric analysis showed that each single fuel had pyrolysis and combustion characteristics based on its own main pseudo-components (hemicellulose, cellulose and lignin).
