摘要
应用API579-2007《合于使用》中的火灾损伤评价方法，对某炼油厂的一座过火减压塔进行了合于使用评价。本评价将过火减压塔划分为6个热暴露区，结果显示：Ⅰ～Ⅳ区域免于评价，允许继续使用；V级区域可以继续使用；VI级区域不满足继续使用的标准，应更换新钢板后重新检测并符合标准规定，方能继续投入使用。
Fitness for service assessment of a fire vacuum tower in oil refinery was carried out by applying fire damage evaluation method from API 579--2007 Fitness-for-Service. In this assessment, the fire vacu- um tower was divided into six heat exposure zones. The assessment results showed that zones I ～IV were free to evaluation, zone V can continue to use and zone VI should replace for new plates and have re - examination to continue to put into use because it does not meet the use standard.
