Abstract (en)
For improving predictability and stability of the hot process gas output of a torch apparatus (1; 1'), in particular a manually guided ambient air torch apparatus, the torch apparatus comprises a first, upstream section, the upstream section including a combustible gas intake member (2) and a gas mixing tube (4), and a second, downstream section, the downstream section including a burner array (12; 12'), the burner array being flow connected to the combustible gas mixing tube (4) by a flow spreader (7; 7'), the burner array together with the flow spreader being enclosed by an enclosure (21; 21'), the enclosure being configured to allow ambient air to enter at an upstream located position and to mantle the hot process gas output produced by the burner array.
