A study was made of the numerical solutions of the equations representing heating of a reactive, homogeneous, opaque solid by a constant flux of energy. Depletion of reactants was considered. Attainment of ignition critical conditions was defined in terms of behavior of the surface temperature due to self heating after termination of external heating. For a wide range of physical and chemical parameters, it was found that 1 critical conditions are relatively insensitive to reaction order 2 the critical ignition temperature has an upper limit approximately equal to the adiabatic solid phase reaction temperature and 3 critical conditions are correlated to an accuracy of 4 by empirical expressions including the physical and chemical properties and based on simple heat balance arguments.
