电弧炉煤氧助熔用内混式煤氧枪

Internal mixing Coal-oxy burner for EAF steelmaking

在电弧炉煤氧助熔外燃式煤氧枪的研究基础上，对内混式煤氧枪进行了试验研究，探讨了所研究因素对煤氧枪的轴向速度及火焰燃烧特性的影响，并通过研究来获得煤氧枪设计和运行的依据，对电炉炼钢工艺进一步降低能耗是有意义的。

Based on investigation on the external mixing coal-oxy burner, the internal mixing coal-oxy burner has been developed. The paper inquires into the influence of the researched factors on the axial veiocity and flame characteristics of internal mixing coal-oxy burner to get the base for the design and operating of coal-oxy burner,It is important for reducing energy constimption further for EAF steelmaking.
