黄磷储罐火灾热辐射下的最小安全距离

Minimal safety distance under heat radiation of the fire in the storage tank of yellow phosphorus

基于黄磷燃烧特性实验获得黄磷燃烧特性参数,研究黄磷储罐火灾在热辐射下的最小安全距离,为防火间距的制定提供依据。利用理论计算的方法对黄磷储罐火灾热辐射进行计算,得出最小安全距离。计算结果显示:黄磷储罐火灾热辐射下最小安全距离为7.8m,大于实际的6m,办公室不安全,需要做防火处理。

Based on the combustion characteristics experiments of yellow phosphorus,to obtain the characteristic parameters on the combustion of yellow phosphorus,minimal safety distance under heat radiation of the fire in the storage tank of yellow phosphorus was studied,so as to provide the basis for the development of fire separation.The method of the theoretical calculations was used to calculate heat radiation of the phosphorus tank fire,and to obtain the minimum safety distance.The results showed： minimal safety distance under heat radiation of the fire in the storage tank of yellow phosphorus is 7.8 m,larger than the actual distance of 6 m,thus the office is unsafe,needs to do fire prevention processing.
