Filtrational combustion of gases. Present state of affairs and prospects

The review considers the problem of gas combustion in inert porous media. It includes the classification of steady-state combustion regimes, the structure and characteristics of thermal waves, the interaction between physico-chemical elementary processes in combustion waves, the mechanisms of reaction zone propagation. The ways of the development of the theory of this combustion type and its role in the understanding of similar combustion processes are discussed.
