ABSTRACT:
A device for spreading a flame, comprises at least one principal nozzle (35) delivering a jet of combustible gas or combustion supporting gas (6); at least one secondary nozzle (8) delivering a jet of combustion supporting gas or combustible gas (12) which flows next to the principal jet and which has a substantially constant thickness. At least one curved surface (9) is disposed tangentially to the jet of secondary gas so as to deflect it by the Coanda effect, to draw in the principal jet of gas (6) and to mix the gas of the secondary jet (12) and the gas of the principal jet (6) to form a flame.
