1.结构参数的选择稳燃器是保证燃油稳定着火的重要部件。目前它在运行中露暴的主要问题有两个:一是热烟气回流太强,造成喷咀结焦;二是热烟气回流不足,使油枪伸进较长,着火落后。燃烧器出口的回流强度不仅与稳燃器结构有关,而且与稳燃器所处的位置以及二次风出口动态有关。因此目前还未找到有关回流强度的定量规律。此外,不管是着火或结焦,还与喷咀的雾化角和雾化细度等因素有关。因此对稳燃器的最佳结构只能给出一个 1. The choice of structural parameters Stabilizer is to ensure that the fuel is an important part of a stable fire. At present, there are two major problems in its operation. One is hot flue gas return is too strong, resulting in nozzle coking; the other is hot flue gas backflow is insufficient, so that the oil gun into the longer, behind the fire. The backflow intensity of the burner outlet is not only related to the structure of the burner, but also to the location of the burner and the outlet of the secondary air. Therefore, we have not found the quantitative law of reflux intensity. In addition, whether it is fire or coking, but also with the spray nozzle atomization angle and fineness and other factors. Therefore, the best structure of the burner can only give one
