Fire is the rapid oxidation of a material. Water is 2 hydrogen and 1 oxygen. Every molecule is fully oxidized. It’s also a common byproduct of fire. Therefore, you can’t burn it, because it’s already burnt

    Ah so it’s hot enough to electrolyze water and then when the hydrogen and oxygen gas move out of that heat zone, they’re still in a hot enough area to re-oxidize into water, burning the hydrogen. Neat.

        Yes.

        Not only will metal fires break apart the water into oxygen and hydrogen, but they will consume the oxygen, as the metal oxide is a more stable energy state than is water. So you end up with a billow of hydrogen coming off the fire that mixes with the oxygen just above (because lighter gases rise) the oxygen-depleted zone of the fire, and it combusts there.
