Abstract

Combustion processes of wood pellets in hot cross flows have been studied on the basis of a series of unsteady simulations. Results show that the pellet ignition occurs with a cross flow temperature higher than 600°C. The locus of the ignition point changes depending on the free stream temperature, while combustion of char occurs throughout the pellet for all investigated temperatures. The total combustion time in addition to the time required for volatile materials to decrease occurs more rapidly with inlet temperature changes from 600°C to 700°C than that from 700°C to 800°C. Keywords: wood pellet, combustion, Computational Fluid Dynamics (CFD).
