Extinction Phenomena in Smouldering — Thin Strips —

概要

Next to the previous investigation of the smouldering of cellulosic materials, a theoretical explanation was given for the transition from the steady burning to extinction. The steady burning-extinction phenomena of vertically downward smouldering along card-board strips were studied. For different sizes of strips, the critical temperature, at which the steady burning shifts to the unsteady burning or extinction, were measured. The results show that the critical ambient temperature rises with increase in size of strip, and that, above an surrounding temperature of 60 °C, no extinction occurs for any size of strip.
