加热炉燃烧器作为加热炉的核心组件,钢坯产品的质量、产量等直接与其稳定性和火焰长度有关,因此燃烧器的设计与开发一直是人们关心的重要研究课题。本文通过CFD仿真模拟对不同加热炉燃烧器火焰长度进行了理论计算和比较,得到了火焰长度与燃烧器喷射角度有关的结论。此外,还对不同燃气流量和热值的情况下进行了仿真模拟。 As the core component of heating furnace, the quality and output of billet products are directly related to its stability and flame length. Therefore, the design and development of burners have always been an important research topic that people are concerned about. In this paper, the flame length of different furnace burners is theoretically calculated and compared by CFD simulation, and the conclusion that the flame length relates to the burner spray angle is obtained. In addition, simulations were performed for different gas flows and heating values.
