近年来，工业型燃烧器的性能评价备受关注。点火和稳定燃烧过程对于考核燃烧器的质量具有重要意义。平面激光诱导荧光（PLIF）技术可应用于重油锅炉，将该技术扩展到工程应用。考虑到台架测试环境复杂，采取了温度控制、防潮等措施，提高了PLIF检测的可能性。在本文中，报告了点火后火焰生长的实验研究。从点火火焰的形状可以观察到褶皱结构；将描绘其轨迹。结果表明，皱纹结构向下发展，即偏离气流方向。火焰的位移速度用来描述燃烧速率。强制点火和自燃的火焰形状都获得了良好的一致性。此外，燃烧中心偏离锅炉中心，可能是由于燃烧器组件的一些不规则性，这对燃烧室的设计至关重要。
Over recent years, much attention has been paid to the performance evaluation of industrial-type burners. The ignition and stable combustion process are of great significance in assessing the quality of burner. The planar laser-induced fluorescence (PLIF) technique can be applied to heavy oil boilers, extending this technique to engineering applications. Considering the complex environment of the bench test, measures such as temperature control and moisture proofing are made to improve the possibility of detection using PLIF. In this paper, an experimental investigation of flame growth following ignition is reported. A wrinkled structure could be observed from the configuration of the ignition flame; its trajectory will be depicted. The results showed that the wrinkled structure developed downward, i.e., by deviation from the direction of the airflow. The displacement velocity of the flame was used to describe the combustion rate. Good agreement was obtained for the flame shapes of both forced ignition and autoignition. In addition, the center of combustion deviated from the center of boiler, possibly due to some irregularity in the burner’s assembly which was critical to the design of the combustion chamber.
