Abstract:
The processes of heat and mass transfer, such as drying, pyrolysis and heating of biomass particles during torrefaction in a flow reactor are considered. It is shown that for small particle size (~ 1 cm) heat transfer between the heating flow and the particles does not depend on mass transfer and the characteristic time torrefaction determined by the pyrolysis of biomass particles. Analytical dependences of concentration of the waste component of pellets under the condition of small time of heating and evaporation in comparison to the time of pyrolysis are made.
