Extinguishing performance of portable water mist system was studied in this paper, considering the effects of additive addition and its type. The experimental results were statistically processed and numerically analysed by mathematical software. The results demonstrated that water mist with additive solution can extinguish pool fire efficiently due to physical and chemical mechanisms. The salt solution produces better fire control result than surfactant solution at low concentration, whereas the surfactant solution brings the better one at high concentration. Furthermore, the salt solution and surfactant solution have similar fire expansion behaviours to pure water in fire suppression with portable water mist system. The study, based on the application of the portable water mist system with additives, revealed that the system performed well on fire suppression and could be useful on movable fire control. |
