油罐火灾燃烧速度的实验研究

燃烧速度是油罐火灾中决定火焰温度和辐射热的重要参量，其变化规律也决定着火灾中灭火预案及战术的制定．通过对直径为1．0m、1．5m和2．7m的汽油和柴油储罐火灾的燃烧实验，获得了油品的瞬时燃烧速度和平均燃烧速度的变化规律．研究得出，油品的种类和油罐直径对平均燃烧速度影响较大，另外随着油初温的升高、风速的加大以及升高油位，都会增大油品的燃烧速度．在此基础上，拟合了相应条件下的实验关联式，并简要分析了各种影响因素的燃烧学机理．

Experimental Study on the Burning Rate of Oil Tank Fires

Burning rate is the important parameter that influences the flame temperature and thermal radiation,and it also determines the fire prevention plan and firefighting tactics.By carrying out the experiments on gasoline and diesel oil tank fires with diameters of 1.0,1.5 and 2.7 m,the regularity of instantaneous burning rate and average burning rate were acquired.It can be obtain from experimental results that oil species and tank diameter have an effect on the average burning rate.In addition,high oil temperature,strong wind and high the oil level can increase the average burning rate.On the basis of above,the corresponding correlations in different conditions were developed and the combustion mechanisms of these influencing factors were briefly analyzed.
