初始温度对丙酮爆炸下限的影响

The Effect of the Initial Temperatures on the Lower Explosion Limits of Acetone

利用公式?U=-0.1196n/λ计算了丙酮在不同初始温度时爆炸形成的温度,进而计算了爆炸后形成的压力。初始温度0℃时,丙酮的爆炸下限为4.2%,爆炸后的计算温度835.2K,压力为322.83 kPa。初始温度50℃时,丙酮的爆炸下限为4.0%,爆炸后的计算温度为856.0K,压力为279.14 kPa。初始温度100℃时,丙酮的爆炸下限为3.2%,爆炸后的计算温度为809.9K,压力为226.96kPa。

The temperatures produced by acetone explosions at different lower limits are calculated by the formula, AU = -0.1196n/k and the pressures produced by explosions are calculated. If the initial temperature is 0℃, the lower explosion limit is 4.2%, the calculated temperature is 835.2K, the calculated pressure is 322.83kPa. If the initial temperature is 50℃, the lower explosion limit is 4.0%, the calculated temperature is 856.0K, the calculated pressure is 279.14kPa. If the initial temperature is 100℃, the lower explosion limit is 3.2%, the calculated temperature is809.9K, the calculated pressure is 226.96kPa.
