对武钢热轧厂４ 号加热炉改造用油气混用可调焰烧嘴进行了详细的试验研究，确定了烧嘴的结构尺寸，得到了烧嘴的性能参数。煤气流量在１３２ ～８８５ｍ３／ｈ 、重油流量在４４ ～２２０ｋｇ／ｈ、空气消耗系数在１ ．０３ ～１．１８ 范围时，烧嘴能够稳定燃烧，烟气中ＣＯ 的含量低于０ ．１ ％ ，噪音低于８５ｄＢ（Ａ） 。烧嘴在现场使用效果良好。
A detailed experimental study was carried out on the adjustable flame burner mixed with oil and gas for the revamping of No.4 furnace in WISCO hot rolling mill. The structure size of the burner was determined and the performance parameters of the burner were obtained. Gas flow in the 132 ~ 885m3 / h, heavy oil flow in the 44 ~ 220kg / h, the air consumption factor of 1. 03 ~ 1.18 range, the burner can burn stably, the content of CO in flue gas is lower than zero. 1%, noise less than 85dB (A). Burner in the field with good results.
