✦ Synopsis

A criterion for threshold gas phase thermal ignition of cellulose materials heated ~ith radiant energy is analytically derived from theory. The derived threshold criterion, which does not depend upon detailed infornmtion on gas phase kinetics, states that the radiant heat flux applied to the fuel must be twice the heat flux required for pyrolysis of the fuel less the heat conducted into the solid phase. The heat of pyrolysis calculated from the derived condition, using published data fox the remaining parameters, is within the expected range.
