摘要:
为了探讨开口的位置与尺寸对受限空间内的细水雾灭火有效性的影响，设计了一个尺寸为1.2 m×1.2 m×1.2 m的特殊受限空间模拟实验台，开展了一系列细水雾灭火对比实验，测量了烟气温度以及灭火时间等实验参数，通过改变实验燃料、火源功率、开口尺寸、开口位置等因素来研究开口对特殊受限空间内细水雾灭火有效性的影响规律。结果表明：在特殊受限空间内，相同条件下，开口位置由下至上，细水雾抑制火灾有效性由低至高；开口尺寸由大至小，细水雾抑制火灾有效性由高至低。当开口尺寸足够小以后，细水雾抑制火灾有效性反而会逐渐增强。
Abstract:
In order to investigate the influence of the position and size of opening in the confined space on the fire suppression effectiveness of water mist, a simulation experimental platform for the specific confined space with the size of 1.2 m×1.2 m×1.2 m was designed. A series of contrastive experiments on the fire suppression by water mist were conducted and some experimental parameters such as smoke layer temperature and fire-extinguishing time were measured, then the influence of opening on the fire suppression effectiveness of water mist in the specific confined space was studied through changing some factors such as the fuel type, the heat release rate of fire source, and the size and position of opening. The results showed that the fire suppression effectiveness of water mist increases with the higher opening position and the bigger opening size under the same experimental conditions in the special confined space. However, the fire suppression effectiveness of water mist increases when the opening size is small enough.
