摘要
在细水雾扑灭油池火的初期,某些油池火焰会有一个突然强化、剧烈燃烧的情况发生。通过实验研究证明,酒精等与水互溶的液体不会发生强化现象,汽油和柴油等不溶于水的液体则有明显的强化现象;同时,发生强化现象的根本原因是共沸使得细水雾到达燃料表面后急剧沸腾而强化燃烧。
The oil pool flame would be enhanced suddenly and burn violently at the beginning when water mist extinguishes the pool fire burning by some type of liquid. In this paper, experimental studies have shown that alcohol which dissolves in water does not enhance the pool fire, and gasoline and diesel which do not dissolve in water enhance the pool fire obviously, at the same time, the real reason of enhancing the pool fire is that azeotropy makes the water mist which reaches the fuel surface boiling sharply and then enhance the combustion.
