FIELD: metallurgy.
SUBSTANCE: method is based on use of single tuyere where many jets escape from its nozzles. Burning medium formed around gas jets is used for forming many coherent gas jets at maintenance of flow of each jet over its entire length. Tuyere has part projecting beyond end surface of its end-piece, thus forming the space connected with nozzle orifices and fuel and oxidizer discharge devices located on end surface of end-piece around nozzle orifices. Burning medium is formed in this space around gas jet due to recirculation of fuel and oxidizer fed to it. Proposed method employs only one tuyere for obtaining many coherent gas jets which may move without decrease in velocity or increase of gas flow diameter.
EFFECT: enhanced efficiency.
