大型商用燃油炊具面积巨大,并涉及到大量热油,灭这种大型商用燃油炊具火灾非常困难.利用水雾系统对大型商用燃油炊具保护进行了研究,从理论和试验对水雾系统的灭火机理以及扑灭大型油池火灾需要达到的相关标准进行了研究.根据灭火机理和相关标准,设计了两套水雾灭火系统,进行了一系列的实体火灾试验.研究表明,两套水雾灭火系统成功地扑灭了大型油池火灾,有效预防了复燃.其灭火性能取决于水雾系统类型、喷射压力以及炊具罩的位置.

Large oil fires occurring in industrial oil cookers are very challenging to extinguish due to their size and the large amount of hot oil involved. This paper reports a study to use water mist for large industrial oil cooker protection. The extinguishing mechanisms of water mist and corresponding criteria required for extinguishing large pool cooking oil fires were investigated both theoretically and experimentally. Based on the extinguishing mechanisms and required criteria, two water mist systems were developed in the present work. A series of full-scale fire tests were conducted in a large industrial oil cooker mock-up. The study showed that the two water mist systems presently developed worked effectively to extinguish large cooking oil fires and prevented them from re-igniting. Their extinguishing performance was determined by the type of water mist system, discharge pressure and hood position in the oil cooker.
