O-203 Numerical simulation through the pyrolysis of woody biomass with shrinking volume

Abstract

In our previous report, transport phenomena in the rapid pyrolysis of woody biomass was investigated experimentally. From the results, the pyrolysis depends strong on the setting temperature and can be divided into three processes; i.e., i) evaporation of water, ii) decomposition of biomass and iii) decomposition of generated char. In this work, heat transfer in the biomass layer through the slow pyrolysis has been also investigated experimentally and theoretically. Secondary, the shrinking process of the biomass layer through the pyrolysis has been also investigated experimentally.
