operate the combustion systems. The inter-related events
through which single particles of solid fuel undergo during
combustion are heating up, drying, devolatilization and
finally the combustion of the volatiles and char. Fig. 2
shows a schematic description of these processes for straw
or wood [11]. The temperatures at which devolatilization
and char combustion start, the influence of drying on the
devolatilization process, the composition of the devolatilization
products and the effect of volatile release and
combustion on the overall combustion process, are all
important information required to understand the combustion
characteristics of agricultural residues. This section
discusses some of these issues.
