ESTIMATION OF THE PARAMETERS OF COMBUSTION OF THE SURFACE OF NATURAL COMBUSTIBLE MATERIALS BY THE THERMOGRAPHY METHOD

The results of an experimental investigation into the parameters of combustion of peat and wood using thermography have been presented. The mechanism of propagation of smoldering over the peat surface has been identifi ed. The temperature fi eld on the surface of peat during its combustion under the infl uence of a local heat source has been obtained, and the velocity of propagation of the smoldering front has been estimated. Using the IR-diagnostics method, temperature distributions have been obtained over the surface of wood specimens exposed to heat action under conditions of a ground fi re with and without fi re-retardant treatment.
