ISO城市区域消防流量方法适用性

Discussion on applicability of ISO′s methods of calculating city fire suppression flow

引用美国ISO城市区域消防用水流量方法,选取城市区域3栋典型建筑物,分别计算建筑物的消防流量设计值、ISO城市区域消防流量方法NFF值和实际扑救火灾所需流量值并进行对比,对ISO城市区域消防用水流量方法的适用性进行分析。结果表明:建筑物的消防流量设计值小于实际火灾扑救所需流量,而NFF值基本可以满足扑灭火灾所需流量;ISO流量方法比较适用于我国城市区域消防流量的确定。

Using the American ISO＇s methods of calculating city fire suppression flow, three typical buildings in city area were selected to calculate the fire flow design value, NFF value of ISO＇s methods and the actual value required for firefighting of burned buildings, and the applicability of this method in China was analyzed. The results showed that the design values of fire flow of buildings were lower than the actual firefighting values, while NFF value could make sure that the fire could be put out; The ISO＇s methods of calculating city fire suppression flow could be used to design city area fire suppression flow in our country.
