    • The following invention relates to an injector-burner for applications in the metalwork field, in particular for use in electric arc furnace melting processes having a frontal head with two series of holes arranged in two concentric crowns, the inner crown of holes used to feed fuel and the outer crown used to supply a supporter of combustion. A central hole is also provided, which is fitted with an oxygen injection nozzle. The holes of the two crowns are divided into groups separated by circular sectors without holes, in order to create a number of flames and are inclined in such a way as to give the gases supplied, and consequentially the flame generated, a rotation around the injector-burner axis. By regulating the flow-rates of the fuel and the supporter of combustion supplied to the various holes, the injector-burner is able to regulate the flame shape in burner mode and also in injection mode, thus guaranteeing optimum performance in all modes.
    • 以下发明涉及一种用于金属加工领域的喷射器 - 燃烧器,特别是用于电弧炉熔化工艺中,该炉具有具有布置在两个同心冠中的两个孔系列的前端头,用于供给燃料的孔的内冠 和用于提供燃烧支持者的外冠。 还设有一个中心孔,它配有一个氧气喷嘴。 两个冠部的孔被分成不带孔的圆形扇区分开的部分,以便产生许多火焰并以这样一种方式倾斜,以便产生供应的气体,从而导致产生的火焰,围绕喷射器的旋转 - 加力轴。 通过调节供应给各种孔的燃料和燃烧支撑体的流量,喷射器 - 燃烧器能够调节燃烧器模式和喷射模式下的火焰形状,从而保证所有模式下的最佳性能。
