摘　　要：利用小型模拟储罐进行超细干粉扑救储罐火灾的试验研究。分别取灭火剂2 000、1 500、1 250、1 000g进行灭火试验,确定最小灭火剂需求量;喷射器与罐壁的夹角分别为22°、15°和5°。试验结果表明:在储罐开口状态下,该超细干粉灭火剂的灭火浓度为133g/m,是检测报告中所述灭火浓度的181%;灭火剂喷射器在静止空气中的最大喷射距离约18m,横向覆盖距离为12m;灭火系统的喷射压力为1.5 MPa;喷射器与罐壁的安装角度为15°,说明超细干粉灭火系统具有扑救小型储罐火灾的能力。Experiments of super fine powder fire fighting system on tank fire extinguishment were carried out with small scale simulating tank. The mass of extinguishing agent was 2 000, 1 500, 1 250 and 1 000 g. The minimal amount of extinguishing agent to put out the fire was obtained. The angel between ejec- tor and tank wall were 22°, 15° and 5°. The experiment results showed that the super fine powder agent application density was 133 g/m3, which was 181% of that provided in inspection re- port. The maximum spraying distance of ejector was about 18 m with wide coverage range of 12 m. The spray pressure of the system was 1. 5 MPa. The angle of ejector against tank shell was 15°. The experiments results showed that the designed su- per fine powder fire fighting system could extinguish small scale tank fire.
