Abstract
The invention concerns a burner for producing a jet of hot gases, in particular to shrink plastic foils, with a pressure distribution chamber of a fan-like contour joined to a mixture feed means and merging at its wide end into a combustion chamber of an elongated cross-section, a flame holder being mounted in the transition zone between the pressure-distribution and the combustion chambers. In order that such a burner evince more reliable and constant properties while being of a simple design, the flame holder shall be a bar of shaped section extending across the entire width of the pressure-distribution and combustion chambers and together with the adjacent walls shall form passageway-gaps for the combustion gases.
