METHOD OF CREATING CUMULATIVE JET AND NONEXTENDED SYSTEM FOR CUMULATIVE JET CREATING, WHICH HAS BALANCED CANALS FOR MAKING FIRE JACKET

摘要

FIELD: metallurgy.;SUBSTANCE: method includes output of one gas jet as minimum through the nozzle of tuyere, the outside surface has radial situated the first and second rings of holes for feeding gaseous fuel and oxider, which create the fire jacket around the initial gas jet. At the same each hole of the second ring is situated coaxial with some of the hole of the second ring. For realizing this method it is suggested the device of the tuyere.;EFFECT: it is provided the generating of coherent gas jet for installing the area of gas recirculation.;10 cl, 3 dwg
