An important feature of tank pool fire is that the targets of interest for critical effects may include other plant units, such gas pipelines, storage sites, process sections, with heat transfer modes not limited to radiation. This paper, which takes inspiration from a recent work of the same authors, considers the physical model of a rectangular pool-fire to provide an analytical trend of the surface emissive power depending on the flame height. The capability of the approach is proved by an applicative case-study where the possible escalation from pool fire to a coke oven gas pipeline failure is analysed, within the context of a coal dry distillation plant. The possibility of escalation with pipeline damage is thoroughly discussed, in order to develop a detailed design of the emergency response capability considering the provision of human and logistical resources.
