Abstract

Using a self-built water mist fire extinguishing experimental platform, the suppression process of water mist nozzles on oil pool fires in different spatial positions was studied, and it is hoped that it can provide theoretical support for the installation of water mist fire extinguishing nozzles for floating roof oil tanks. The spray pressure is set to 4Mpa, the fire source is crude oil, 150ml of fuel is taken each time, and the oil basin is 30cm in diameter. The experiment is designed for multiple sets of comparative tests. The results show that when the nozzle is facing the oil pan, the height of the nozzle has a significant influence on the fire extinguishing effect. The higher the nozzle height, the longer the fire extinguishing time. When the nozzle is shifted in the lateral position, the height of the nozzle and the distance of the lateral offset affect each other, and there is a critical lateral position. The crucial position in this experiment is 7.5cm-10cm. Beyond this distance, regardless of the height of the nozzle, Inability to effectively extinguish the fire.
