摘要： 使用氯化钾和碳酸钾作为超细水雾添加剂，纯水超细水雾作为对照，无水乙醇、90%乙醇和75%乙醇作为燃料，采用改进的Cup burner 装量，获取超细水雾临界灭火浓度，分析灭火过程。实验表明，随着酒精度数升高，含钾盐超细水雾熄灭乙醇火焰的临界灭火浓度也逐渐升高，并且含碳酸钾超细水雾的灭火效果稍好于含氯化钾超细水雾。

Abstract: In this paper, potassium chloride and potassium carbonate were used as superfine water mist additives, pure water superfine water mist was used as a control, anhydrous ethanol, 90% ethanol, and 75% ethanol were used as fuel, and a novel ultra-fine water mist critical fire extinguishing concentration experiment device was used. Experiments show that as the degree of alcohol increases, the critical fire extinguishing concentration of the potassium salt ultrafine water mist to extinguish the ethanol flame also gradually increases, and the fire extinguishing effect of the ultrafine water mist containing potassium carbonate is slightly better than that of the ultrafine water mist containing potassium chloride.

Key words: ultrafine water mist, ethanol flame, critical extinguishing concentration, potassium chloride, potassium carbonate
