Using unsteadiness of the processes in diagnostics of burning objects

A technique for studying burning processes based on their unsteadiness is proposed. The temperature and spectral dependences of emitting and absorbing characteristics of MgO particles and their mixtures with gases at high temperatures are studied. The rates obtained allow one to solve problems of radiative heat transfer. The problem of existence of equilibrium between the gaseous and condensed magnesium oxide in the combustion zone is discussed.
