| 摘 要： | 利用尺寸为38m(长)×21m(宽)×5.4m(高)的真实商业建筑火灾场景,使用3.0 MW真实柴油池火火源,研究排烟口与挡烟垂壁组合控制烟气时挡烟垂壁高度、排烟口位置和朝向等因素对烟气控制效果的影响。在火灾规模、排烟量和排烟系统启动时间都一定的情况下,挡烟垂壁的高度是影响烟气控制效果的关键因素。排烟口距火源越近烟气控制效果越好。排烟口的朝向对烟气控制效果的影响并不显著。

| Abstract: | Using 3.0MW real diesel pool fire as the fire source,the impact of the height of smoke screen and the location and orientation of the exhaust port on the effect of smoke control in the real commercial building fire scene was studied,with the combination of exhaust port and smoke screen.The size of building is 38m(length) ×21m(width) ×5.4m(height).In the case of certain fire scale,emission of smoke and smoke extraction system start-up time,the height of smoke screen is a key factor influencing the effect of smoke control.The nearer exhaust port is away from the fire source,the better effect smoke control can get.The impact on the smoke control from the orientation of exhaust port is not significant. |
