Thermal analysis of wood fuel pyrolysis process
The paper presents the results of studies of conversion process on the laboratory pyrolysis reactor and the results are compared with data, obtained in model experiments by thermogravimetric analysis (TGA). The heating rates were compared in the pyrolysis reactor and in the laboratory furnace of TGA in the pyrolysis process of wood biomass conversion. The laboratory pyrolysis reactor, as a part of the multistage gasification facility of low-grade solid fuel, was launched in several modes. Three experimental modes of the device operation with different screw speeds and fuel flow rates through the reaction shaft were tested. The temperature profile of fuel and wall along the length of the pyrolysis reactor was shown. The temperature up to 600 °C was recorded in a mode with a low fuel flow rate, and in the end of the reaction zone the fuel temperature was close to that of the wall. The kinetic coefficients and conversion rates for the wood biomass pyrolysis were calculated from the obtained equation. Therefore, the calculated data of the conversion rate and the pyrolysis parameters, based on the TGA data, can be used to further develop the pyrolysis reactor and evaluate the parameters of its operation. © 2018 Institute of Physics Publishing.
