油锅火灾如何爆炸

[编辑 | 编辑源代码]
  • Oil gets so hot that it catches fire all by itself.
    油变得太热，会自行着火。
  • Water is poured into the burning chip pan.
    将水倒入燃烧的油锅中。
  • Water is denser than oil, so it sinks to the bottom of the chip pan (shown in red). As the water touches the bottom, it is heated above its boiling point and instantly vaporizes.
    水的密度比油大，因此会沉入油锅底部（以红色显示）。当水接触底部时，它会被加热到沸点以上，并立即汽化。
  • The water vapour expands radpidly, ejecting the burning molten oil out of the chip pan and into the air where its surface area increases greatly and combustion proceeds much faster.
    水蒸气迅速膨胀，将燃烧的熔融油从油锅中喷射到空气中，其表面积大大增加，燃烧速度也大大加快。
  • Oil is heated strongly
    油被强烈加热
  • After some time, it gets hot enough to catch fire
    一段时间后，它会变得足够热以着火
  • Pouring a very small amount of water into the fire ejects a plume of burning oil
    倒入少量水会喷射出一股燃烧的油
  • With all the oil burned, there is no more fuel to supply the fire
    随着所有油的燃烧，不再有燃料供应火焰
