T his paper analyses the existing literature, and considered the new problems caused by the burning accident of thermal insulation materials attached to the steel structure in recent years . In the process of combustion, thermal insulation materials will drip and melt, producing a large amount of liquid fuel. The combustion of thermal insulation materials attached to steel (diameter long er than 0.2 m) can be regarded as large pool fire combustion, and a mathematical model is established to study the reverse thermal conduction behavior of the combustion of combustible materials attached to steel.
