摘　　要：分析认为一段炉对流段振动的原因是高温烟气在局部发生剧烈变化,在气流紊流作用下造成的,当遇到工艺参数波动时振值随之波动,根据不同原因采用相应措施,取得了预期的效果。It is shown by analysis that the reason for the vibration of Primary reformer convection section is that high temperature flue gas changes fiercely in some places, resulting in turbulent gas flOW. measures The vibration amplitude changes with the fluctuation of process parameteres. Corresponding were taken accordingly and predicted effect was reached.

关 键 词：对流段 烟气 临界流速 烟气分布器
