一、沸溢及其危险性 原油或重油火灾区别于一般轻油火灾的特点之一是容易出现“沸溢”。当原油或重油表面燃烧时,释放出大量的热能,油面温度能达到几百度。这些燃烧热通过油逐渐向深处传递,以至传递到贮油槽底部的水层。当水的温度达到沸点时,水蒸发而产生的大 First, the boiling overflow and its risk Crude oil or heavy oil fire different from the general characteristics of light oil fire is prone to “boiling overflow.” When the surface of crude oil or heavy oil burns, release a lot of heat, oil surface temperature can reach several hundred degrees. The heat of combustion is gradually transferred through the oil to the depths and to the water layer at the bottom of the sump. When the water temperature reaches the boiling point, the water evaporates and produces large
