Conclusions

  1. 1.

    Discrete dispersion, in distinction from continuous, characteristic for systems with a bulk density, can bring about relaxation processes, not only in the combustion zone but beyond its limits. The reason for their appearance consists in the breakdown of part of the combustion zone with a maximal gas evolution.

  2. 2.

    The conditions and the mechanism of the effect of discrete dispersion on the convective combustion of porous systems is discussed. It is pointed out that

  1. a)

    taking account of discrete dispersion, it is obviously impossible to realize truly steady-state combustion conditions;

  2. b)

    if the pressure at the boundary of the zone of throwover is less than the external pressure, there is not stabilization of convective combustion by the mechanism of discrete dispersion.

  3. 3.

    The possibility of the realization of convective combustion conditions, determined both by the pressure in the pores of the substance and by the external pressure, is noted.

  4. 4.

    The possibility of stabilization of the convective combustion of a porous system by a periodic change in the pressure in the burn-up zone (the external pressure) is demonstrated.
