Abstract
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.
