Will water mist extinguish a liquid fire rapidly?

摘要

Local professionals are quite worrying about whether a water mist fire suppression system (WMFSS) can extinguish a fire rapidly. It was also suggested in the literature that discharging water mist, even under the design operating conditions, might not always control a fire rapidly. To explore more on that, a series of experiments on discharging water mist from low/moderate-pressure system on gasoline fires were carried out at the new full-scale burning facility, PolyU/USTC Assembly Calorimeter at Lanxi, Harbin, Heilongjiang, China. An interesting point identified for quick communication is that for some designs of fuel container, the liquid fire cannot be extinguished even when all the fuels were consumed.
