摘要
使用胜利原油对小尺度沸溢火灾燃烧速率特性进行了实验研究。实验分别记录了直径为0.1m、0.15m、0.2m的原油沸溢油池火灾的燃烧过程,测量了燃烧速率和温度随时间的变化。根据燃烧速率和火焰高度变化对沸溢火灾燃烧进行阶段划分。探讨了不同直径及初始油层厚度对沸溢火灾燃烧速率的影响,在燃烧速率基础上建立沸溢强度模型。结果表明:沸溢火灾燃烧可以分为预燃、准稳态燃烧、沸溢燃烧、火焰熄灭四个典型燃烧阶段;沸溢燃烧阶段的燃烧速率和火焰高度显著大于准稳态燃烧阶段;沸溢火灾各阶段燃烧速率均随油池直径的增大而增大,且沸溢燃烧阶段的增幅明显大于准稳态燃烧阶段的增幅;准稳态燃烧阶段的稳定燃烧速率与初始油层厚度无关,随油池直径的增大而增大;沸溢强度随初始油层厚度的增加及油池直径的减小而增大,并与初始油层厚度和油池直径间的比值呈正比。
