A problem of premixed filtrational gas combustion in a cylindrical annular burner has been solved in the frame of one-dimensional diffusion-thermal model taking into account internal radiative heat transfer in porous burner and radiative heat flux emitted by internal layers of porous material. Two different stationary combustion regimes are detected under the same values of gas flow rate. It was shown that stationary flame radius depends on the initial ignition conditions. Solid and gas temperature characteristics depending on flame radius and gas flow rate are studied. Estimation of the burner radiation efficiency is carried out. Significant difference between temperature characteristics of gas and solid phases and burner radiation efficiency for different combustion regimes are shown.
