| Abstract: | In order to clarify the similarities and differences between biomass combustion and smoldering, characteristics of the two processes have been reviewed. It showed that the combus-tion of a large biomass particle is similar to the natural convection forward smoldering of piled bi-omass powder. Chemical reaction characteristics, transport mechanisms and boundary conditions are compared between two processes. It showed that the reaction mechanisms of drying, pyroly- sis of the two processes are the same. There is a slight difference in mechanism of char oxidation and a significant difference in boundary conditions between the two processes. |
