Abstract

A set of small-scale experiments was carried out to study the effects of material structural properties on the re-ignition characteristics of solid fuels. The influence of other key parameters, such as the incident heat flux and pre-burn, was also carefully investigated. The experiments were conducted on specimens of wood and PMMA using a cone calorimeter. As expected, the effect of water on the re-ignition time was found to be significant. It was also found that the re-ignition characteristics of charring materials, such as wood, are quite different from non-charring materials, mainly due to the structural differences. Based on the experimental observations two different mathematical models were developed to analyse the data for both wood and PMMA samples. Calculations of the re-ignition time made using these models agree generally well with the measurements and confirm that the material structure plays a vital role in its re-ignition behaviour.
