Abstract:
An analytical model was developed to describe the
processes involved in the burning and extinction of
solid materials. Included are flame heat transfer,
charring, transient conduction, and water application.
The model qualitatively describes the burning rate of
both charring and thermoplastic-like solids. It
illustrates how the steady-state heat of gasification
can be derived from peak burning rate test data taken as
a function of irradiance. Experimental data are shown to
support this derivation. The model, in conjunction with
a critical flame temperature, is used to describe
suppression and extinction by water.
