用一种由膨胀珍珠岩材料做成的直径分别为2.3cm、3.0cm和3.7cm球状隔热浮子,对两种油品油罐火灾进行扑救模拟试验。研究结果表明,对于低闪点油罐火灾的灭火效果差,而对于高闪点的油罐火灾,隔热浮子覆盖油液表面,能够减少上面高温火焰对油液面的传热,进一步减弱油液面的蒸发,灭火效果好。
用一種由膨脹珍珠巖材料做成的直徑分彆為2.3cm、3.0cm和3.7cm毬狀隔熱浮子,對兩種油品油罐火災進行撲救模擬試驗。研究結果錶明,對于低閃點油罐火災的滅火效果差,而對于高閃點的油罐火災,隔熱浮子覆蓋油液錶麵,能夠減少上麵高溫火燄對油液麵的傳熱,進一步減弱油液麵的蒸髮,滅火效果好。

In this paper,simulating experiment has been done by putting out two type oil tank fires with adiabatic floaters made of expanded perlite,the diameter of adiabatic floaters is 2.3cm,3.0cm and 3.7cm respectively.The result shows： it is invalid for putting out the lower flash point oil tank fires;but it is effective for putting out the higher flash point oil tank fires,because the adiabatic floaters can float in the surface of the oil tank,it reduces the heat transfer from high-temperature flame to the surface of the oil,and weaken the evaporation of the surface of the oil.
