    This is the same science behind flashback arrestors when using an acetylene torch, the mesh in the arrestor prevents the fire from traveling backwards down the torch into the gas cylinder

      @Goat Sinker it doesn't have to burn far into line to melt the line creating essentially a fire hose of well fire. The lines themselves are just composite and can take some heat, but burning gass from blow back. However it's truly dangerous in more industrial applications using larger volumes. Thank god for arestors

    • Additional Audition
      Additional Audition 4 months ago +2

      @Goat Sinker thanks for explaining the science behind it better, I'm a highschooler with just a basic-enough understanding of what I'm doing when it comes to my torch haha

    • Goat Sinker
      Goat Sinker 4 months ago +5

      You're right. Oxygen can not burn by itself, neither can acetylene, or any other fuel. In a flashback situation the oxygen and fuel mix inside the supply line due to a drop in pressure at the feed source. Apparently this can happen when the torch is clogged and the clog is removed. At that instant it could happen that the oxygen and fuel mix in the supply line due to a momentary reverse flow. But yes, i have a hard time imagining that scenario.

    • Tony George

      @docarii also, the torch pipe is made of metal too which conducts all/any heat from the flame

  • Hyperscience

    Very interesting
    So what happens is that the metal mesh reduces the amount of heat below the flash point of the substance, therefore preventing combustion

    This is also why engines on boats ( mostly gasoline / petrol engines) will have flame arresters to prevent explosions from accumulated fumes. Always ventilate and run your engine space fans before you start your engine especially after refueling. Flame arresters can only do so much.

    This was how gas detector in mines used to work.
    They had a flame encased in metal mesh.
    When the flame started to go crazy in side the metal mesh. you know there is gas in the air and time to leave.(the mesh prevent the flame from igniting all the gas in the tunnel).

    You can not only contain a small explosion, you can do that with big explosions aswell. It's called a flame arrester and is used in industrial plants to contain explosions within a pipe and stop the propagation into vessels.

    This makes me wonder if you can put out a gas fire with a metal spatula type object to separate the fire from where the gas is coming from. Bigger object than a spatula for a bigger fire obviously.
    Wondering if something like that could put out those giant gas fires that have been burning for decades.

  • Max Wilson

    So assuming the actual shock away from the explosion does it break or blow apart the metal mesh, you could actually contain any explosion with a strong enough piece of metal mesh, right?

    • Marino Hernandez
      Marino Hernandez 4 months ago

      Probably depends what's exploding, like if there's shrapnel or bits and pieces of stuff. Also, if the heat is moving faster or slower than the metal's conducting away of heat. But a good conductor will conduct away heat super fast so don't know if the spread is heat can outpace it, even in an explosion.
