Abstract
Typical fire extinguishing agents were considered: water, bischofite solutions, bentonite slurries, and foaming agent emulsions (with a mass fraction of 5% and 10%). The heating temperature range of 150-400 ?? was chosen to correspond to the conditions of rapid thermal decomposition of forest fuels. The experimental research findings suggest that the rates of moisture release depend exponentially on the heating temperature. It was established that the rates of moisture release in the above temperature range may differ significantly for the forest fuels and fire extinguishing agents under study. Conditions were identified when the general approximation equations, presented in this paper, can be used to predict the vaporization characteristics of firefighting liquids.
