The effect of size, shape and pyrolysis conditions on the thermal decomposition of wood particles and firebrands

Two parameters (SSTτ & SSTμ) are defined to correlate the pyrolysis duration (τ) and the final char mass fraction (μ) for various thermal conditions and different particle sizes and shapes. Good correlations were found that may be potentially useful. These correlations may be used to predict the process duration and mass of the volatile compounds for various size and shape particles. They are also useful in determining the lifetime of firebrands.
