Fire internal liquid cooling

An internal liquid cooling system as an active fire protection was implemented in full-scale GFRP panels for beam and column applications, the resulting thermal responses have been introduced and modeled in Chapter 6 and the mechanical responses in Chapter 7. The fire endurance time of each scenario is summarized in Table 9.1 and more details can be found in the previous chapters. It can be concluded that combined mechanical loading and fire experiments on full-scale water-cooled cellular slabs and columns proved the feasibility of an effective fire protection. Fire endurance durations of up to 2 h could be reached at slow water...

For shell-and-tube heat exchangers, limited fire protection may be provided during fire exposure by the liquid in the shell that provides some internal cooling for the shell wall. However, if a spill fire exposure exists and the shell side liquid has low heat capacity, then either water spray or fire resistive material should be applied to the surface of the exchanger itself.
