Abstract: A heating apparatus has a catalytic burner and a thermal receiver which consumes at least one portion of the heat generated by the catalytic burner. The catalytic burner has a member for ejecting a flow of combustible gas, a member for admixing primary air with the flow of combustible gas to obtain a mixture to be burnt, a chamber for distributing the mixture, and a catalytic combustion structure in communication with the distribution chamber. The combustible gas travels into an upstream face of the catalytic combustion structure, and combustion exhaust gases are removed through a downstream face of the catalytic combustion structure. A radiating flameless combustion front is located in the vicinity of the upstream face of the catalytic combustion structure during operation. A thermal receiver extends along virtually the entire surface of the upstream face of the catalytic structure and receives thermal energy.

Abstract: 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.
