A heating device with a catalytic burner for a fuel gas is equipped with a member for regulating the thermal power. The regulating member includes a metal flap for regulating the flow of the mixture to be burned in the catalytic burner. This flap, for example a heat-sensitive bimetallic strip, can move between two positions, namely a first position in which the mixture to be burned is stored in the device or discharged in the manner of a leakage through an orifice in a wall of the heating device, and a second position which allows a maximum flow rate of the mixture to pass through the catalytic burner. The invention applies to all types of heating devices with a catalytic burner.

Gas heating device, with a catalytic burner and regulating member

In a heating applicance with an induced-air catalytic burner, the catalytic burner comprises a refractory core having extending right through it axial conduits for the circulation of the combustible mixture, and dynamic braking means are provided in relation to the core, to make it possible to obtain at the outlet of the burner a speed profile making it possible to prime the ignition of the catalytic burner. A downstream flame heats the core until the catalytic burner is activated, at which moment the downstream flame disappears automatically. The invention applies to all types of heating applicance of the portable type, whatever their uses.
