摘要
调节圆形油盘距壁面的距离,分别对直径为15、30、40、50cm的油盘进行了池火燃烧实验,探讨油盘直径、油盘距壁面的距离对热释放速率、火焰高度和火焰温度的影响。结果表明:火源靠近壁面燃烧时,各燃烧参数均值约是自由燃烧状况的1.14倍;油盘直径越大,燃烧参数随着L/D的增大,下降趋势越大。
By adjusting the distance of the circular pan away from the wall,the experiments on tank fire with different diameter(15,30,40,50 cm) were carried out.The effect of wall to the heat release rate,flame height and flame temperature was studied.The measurements indicate that when the fire near the wall,the mean value of the combustion's parameter was about 1.14 times of the free combustion.The bigger the diameter of the tank,the greater the downward trend of the combustion parameters with L/D'increases.
