- Abstract
- Smoldering combustion is a major source of ignition of highly destructive residential and forest fires. Depending on the prevailing conditions, smoldering is propagated by oxodation of a stable char formed either by nonoxidative thermal degradation (pyrolysis) or by oxidation occurring simultaneously with the initial thermal degradation reactions. In either case, the process must involve combination of oxygen with the substrate and evolution of both pyrolysis and combustion products. The main purpose of this research was to study the kinetics of pyrolysis and oxygen chemisorption and desorption of combustion products under conditions which occur in the smoldering combustion of lignocellulosic materials, which were expected to behave differently from pure cellulose.
