Biomass Pyrolysis Using a Multifunctional Electromechanical Converter and a Magnetic Field

Abstract The wood waste conversion processes in a dry distillation chamber with an executive body based on a multifunctional electromechanical converter were analysed. It was established that under the influence of a low-frequency magnetic field, the properties of moisture evaporating from biomass change, and the evaporation heat decreases. A method for generating negatively charged molecular complexes in the form of water vapour by heating biomass, exposure to the electric and magnetic field, followed by the injection of negatively charged hydroxide ions of water vapour into a solid carbon product at the final stage of the pyrolysis process is proposed. The possibilities of heat recovery of the screw energy technological complex for preheating biomass in a loading device using the thermal energy of the spent heat carrier, the energy dissipative component of the installation’s electromechanical part and the thermal energy utilisation of the produced solid products have been estimated.
