摘要
当储罐遭遇火灾时会导致储罐内气相体积剧烈膨胀和液体沸腾,所需放空量会超出正常呼吸阀的放空量。以API 2000为基础,明确了火灾工况下储罐的湿润面积和火灾时所需的额外放空量,给出了火灾工况下储罐放空量的计算公式和简化公式,提出了火灾工况下紧急放空的措施,为储罐火灾扑救提供了参考。
When the storage tank encounters a fire,it will cause the violent expansion of gas phase volume and liquid boiling in the storage tank,and the required venting amount will exceed the venting volume of normal breather valve.Based on API 2000,the wet area of storage tank under fire condition and the additional venting amount required in case of fire are defined,the calculation formula and simplified formula of tank venting amount under fire condition are given,and the emergency venting measures under fire condition are put forward,which can provide a reference for tank fire fighting.
