Abstract: The disclosure is directed to an improved catalytic combustion arrangement for use, for example, in a gas stove or the like, which has a heat insulation diffusion layer is provided in a catalytic mat layer for the improvement of combustion rate around the catalytic mat, and, through employment of two sets of thermo-couples, a heating burner for the catalytic mat is adapted to burn only during starting of combustion, and to be automatically extinguished upon arrival at a steady combustion state for continuous combustion only by the catalytic mat, with a simultaneous indication of such combustion.
