METHOD AND DEVICE FOR OBTAINING SINGLE COHERENT JET Russian patent published in 2003 - IPC

FIELD: gas flow systems. SUBSTANCE: method includes burning fuel with oxidizer forming flame envelope around many primary coherent gas jets; propagation of said envelope is effected in such way that single gas jet is reliably surrounded. Device proposed for realization of said method includes tuyere with many nozzles; axis of each nozzle is directed at interior angle relative to axis of tuyere and unit for delivery of at least one fuel and oxidizer from tuyere over periphery relative to many nozzles; said unit has first ring of holes located around nozzles on end surface of fuel supply tuyere and second ring of holes located around first ring of holes on end surface of oxidizer supply tuyere. Proposed method makes it possible to obtain more than one gas flow from single tuyere so that gas flows are combined forming single coherent jet. EFFECT: enhanced efficiency. 7 cl, 6 dwg
