“…The pressure of the gas mixture is found from the equation of state and obeys the Dalton law. In contrast to [1,3] where quasi-steady combustion regimes were considered, the present paper deals with unsteady evolution of the process, including the stage of ignition.…”

“…The natural character of gas filtration is caused by its consumption in the chemical reaction with a solid porous fuel. Dilution of the gaseous reagent by an inert gas results in incomplete chemical conversion [1,3]. In the course of combustion-wave propagation, the chemically active gas is consumed, and the inert gas is accumulated in the combustion front and forms a gas "plug."…”

Filtration combustion of a porous layer with natural filtration of the oxidizer diluted by an inert component is studied. The problem of ignition of a porous layer by a heated surface permeable for the gas is solved, and the time of ignition is determined as a function of pressure in the reactor and initial porosity of the sample. Formation of an inert gas "plug" preventing chemical interaction is examined. It is shown that the mean depth of conversion of the condensed reagent in the porous layer depends on the sample length, porosity, pressure of the gas mixture, and concentration of the inert component.
