Study on the Reverse Heat Conduction Behavior of Steel

Abstract

This 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 longer 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.
