摘要： 浮顶作为重要的安全附件，对于内浮顶储罐的整体消防安全至关重要，其耐火性能是影响内浮顶消防安全的关键性能指标，由于现役铝制浮筒式内浮顶事故频发，新型内浮顶产品大量涌现。本文基于全盘组装结构的内浮顶耐火性能试验方法，针对8种类型的内浮顶，开展了21项内浮顶产品的耐火性能测试试验，分析了内浮顶材料和结构对耐火性能的影响，发现铝制浮筒式内浮顶的耐火性能达不到现实要求，新型全液面接触式内浮顶的浮力单元之间及浮力单元和边缘立板之间的密封效果对其耐火性能的影响较大，最终给出了工程应用中内浮顶选型的建议。

Abstract: The floating roof, as a critical safety component of internal floating-roof storage tanks, is essential for the overall fire safety of the tanks. Its fire resistance serves as a key performance indicator affecting fire safety. However, frequent accidents involving in-service aluminum pontoon-type floating roofs have been reported, while numerous new floating roof designs have emerged. This study employs a full-assembly fire resistance test method to evaluate 21 floating roof products across 8 different types. The influence of material and structural design on fire resistance is analyzed. Results indicate that the fire resistance of aluminum pontoon-type floating roofs fails to meet practical requirements. For the new full-liquid-contact floating roofs, the sealing effectiveness between buoyancy units and between buoyancy units and perimeter vertical plates significantly impacts fire resistance. Finally, recommendations for floating roof selection in engineering applications are provided.
