  BLEVE = Boiling Liquid Expanding Vapor Explosion

      Typically BLEVE is used in a petrochemical context, where the hot "boiling liquid, expanding vapor" ignites on contact with oxygen.
      • PaulDavisThe1st 4mo ago
        A BLEVE does not need oxygen to become an explosion. The explosion occurs with the rupture of a tank (that has been heated, increasing the internal pressure and thus increasing the boiling point of the liquid inside, so that it remains liquid). This causes a loss of rapid loss of pressure, which in turn rapidly decreases the boiling point of the liquid, thus causing a sizable part of the liquid to almost immediately boil and cause an expanding "cloud" of gas. When this occurs, you have an explosion that can propel parts of a steel propane tank up to 1/2 mile (at least).

          It doesn't need it but it makes it that much more destructive. Your propane example is such a case - as the hot cloud expands explosively it burns on contact with new oxygen and the heat serves to further perpetuate the process. An overheated tank of propane provides an illustration of the principle on which thermobaric warheads are based.

    My parents are retired fire-fighters. They had an American pygmy goat named Bleve. Those goats commonly have very rotund stomachs[1] that look like they are about to explode.

      > I always love how religious fruitcakes think that their 'god' both is completely omnipotent and infallible but also somehow gives a shit about them, and listens to them. Such a miserable existence looking down on people for their own beliefs. Please get a hobby.

      You don't believe in anything, good for you. But it's not healthy for you to harbor so much hatred and anger for those with different opinions. You're free to worship your golden calf, but why not be civil?
    • SuddsMcDuff 4mo ago
      That is an unhealthy level of contempt you have there.

        You have no idea what brought them there. It was probably horrific. Might still be.

        It's a shame that the moderators on Hacker News tolerate this.

    Not only that, but "there's a gas leak, let's strike it with a wrench" is one of the more interesting attempts I've heard of to win a Darwin award.

  Why bring God into the discussion? Do you think he’s monitoring our lives actively? Why is he a he? Does God have male genitalia?
