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

The present invention relates to a hot air-generating device, combining a catalytic gas burner and a fan. According to the invention, on the one hand, the catalytic burner is of the induced-air type, for which means for mixing primary air in with the pressurized fuel gas are arranged upstream of the burner and, on the other hand, these same means comprise a component for drawing off oxidant air, independently of the circulation conduit which draws off primary air outside the latter. The invention can be applied to any kind of hot air-generating device, such as a hair drier and a hot-air gun for stripping paint.
