摘要
利用自行设计的流淌燃烧实验平台对柴油流淌火在不同坡度条件下的火焰高度、质量损失速率、火焰温度和热辐射等燃烧特性参数进行了研究,并就坡度对流淌火着火初期燃烧状态的影响进行了对比分析。实验结果表明,随着坡度的增加,柴油流淌火的火焰高度、质量损失速率、火焰温度和火焰热辐射均小于同等规模的油池火,且在实验范围内,坡度越大,油品流速越大,火灾特性参数越小,着火初期着火段与泄漏口的距离越大。
The effect of slope on the flame height,mass loss rate,flame temperature and thermal radiation of diesel oil flowing fire were studied using self-designed experimental platform,and the influence of slope on the initial combustion of diesel oil flowing fire was analyzed.The results indicate that the flame height,mass loss rate,flame temperature and thermal radiation are less than the same scale diesel oil pool fire with increasing slope.And with the increase of slope in experimental scope,the oil flow rate increases,the fire characteristic parameters decrease,and the distance between the initial fire position and the drain port increases.
