1. Method of operating an injector burner having a Coanda jet, wherein a propellant fluid is fed under pressure through slots of the jet and a suction fluid is sucked through the propellant fluid with gas as the propellant fluid, characterised in that the suction fluid employed is combustion air, that in the region of the outlet from the Coanda jet a small portion of the gas mixture stream is split off and decelerated, that said portion is ignited and accelerated once more by the main stream, which it encloses as a flame enveloppe, and that after deceleration of the main stream of the gas mixture by the atmosphere, said main stream is ignited by the flame envelope in an region remote from the jet outlet. |
