液化石油气储罐火灾模拟试验——池火灾环境下

液化石油气储罐在火灾作用下，其内部的温度和压力会迅速上升，从而可能引起储罐爆炸，进而酿成危害性更大的二次灾害。为此，对液化石油气储罐在池火灾环境下的热响应情况进行了大量的模拟试验研究。研究发现，储罐在池火灾作用下存在着明显的热分层，热分层加速了储罐内部压力升高的速度；储罐内部温度分布和压力响应受到储罐类型、充装水平等因素的影响，压力随时间的变化关系可以用三次多项式加以拟合。

SIMULATION TEST OF FIRE HAZARD FOR LPG TANKS (1)-UNDER POOL FIRE

When LPG tanks are exposed to external fire, their temperature and pressure will increase rapidly, which may cause the tanks exploding and lead the secondary hazard with much more damage. Therefore, many simulation tests are conducted for the thermal response of LPG tanks when they are exposed to the pool fire. It is found there is the obvious stratification of temperature in the tanks under the action of fire. The stratification of temperature accelerates pressure increasing in the tanks. The temperature distribution and the pressure response are affected by the various factors such as the tank types and the filling levels etc. The pressure can be fitted to the time by the cube polynomial equation.
