Summary:The unstable propagation of combustion of a layer of titanium powder in horizontal and inclined channels under conditions of natural gas filtration is experimentally studied. The critical conditions for the disruption and restructuring of the combustion modes with an abrupt change in heat loss during the combustion of a layer on an inert substrate of variable composition is analyzed. The influence of the convective removal of impurity and inert gases on the processes of the passage of the combustion front over the boundary of dissimilar substrates is studied. The results are interpreted in the model of the heat-filtration stability of combustion in porous media.
