Energy efficient torrefication using a controlled exothermal reaction

This paper analyzes the features of the implementation of the torrefaction process according to the technology developed at the Joint Institute for High Temperatures of the Russian Academy of Sciences using the internal energy of a controlled exothermic reaction. This technology allows reducing energy consumption by several factors for the torrefaction process. In experiments on the installation and in the numerical simulation of the process, an oscillatory change in the temperature of the processed biomass is revealed. A mechanism is presented for controlling the mode parameters of the torrefaction process using the effect of exothermic heat release, which ensures the smoothing of temperature oscillations of the process in a highly energy-efficient manner.
