“And this was the extinguisher here, was it?” the Health and Safety feeb asks. “That’s the one!” I say. “And you don’t know of any reason how it came to be filled with diesel instead of water?” “None!” the PFY lies. “But then it may have been like that when we took the building over!” Luckily the H&S droid isn’t likely to …

    Diesel fuel doesn't burn well.

    But this IS a story after all. Fireball because the diesel needed a little help.

    @the New Turtle - Diesel does burn well

    4.36: It was agreed that the source of fuel for the fireball was finely dispersed diesel fuel

    4.38 The fireball is likely to have been caused by the ignition of airborne fuel within the coach.

    Diesel does burn well

    One a fire has started, it is very difficult to stop, surely you've seen vans that have gone up on the side of the motorway?

    PS: Could do with a few similar devices here.

    It does if it's atomised as a spray and heated, can be explosive even.

    Something like, picking an example out of thin air, spraying it out of a fire extinguisher onto a fire should do the job nicely.....

    DIesel doesn't burn?

    Tell that to the guys at Buncefield - I heard the bang and saw the flames and I can assure it was burning.

    No

    No -- diesel fuel burns *very* well.

    Actually persuading it to start burning, is the difficult bit. You probably could use diesel fuel in an extinguisher and it would put out small fires very effectively.

    I also got a free video projector because of it, OK the screws were all a bit rusty and it was a bit bashed after the little incendiary incident destroyed my employers head office. Even seen a 19" rack of SCSI drives that's been thrown 12 feet or so into the racks on the other side of the room ? So yes you're correct. . . . diesel DOES burn . . . what are these "diesel doesn't burn" people on . . . how do they thing the "bangs" inside a diesel engine occur ?

    The operative phrase was "doesn't burn well", which is true. Diesel is almost inert unless it's either atomised, or heated until it starts to evaporate, or heated and put under pressure.

    Notice that diesel engines don't have sparkplugs? They don't work. You can get a petrol engine running with diesel by priming it with regular petrol and then relying on the pressure of the cylinders to ignite the diesel once it's running, but it'll get pretty annoyed at you in short order and probably won't work after you've stopped it, mostly because it's not mixing enough air and not operating at a high enough pressure to fully ignite the diesel fuel - which is also, incidentally, why putting diesel in a petrol engine produces lots and lots and lots of lovely smoke so everyone can see what a numpty you've been.

    The reason is, the fractions we generally call Diesel aren't particularly volatile. You can toss a match in the stuff and it'll go out. You can do the same with a puddle of regular unleaded tool but it's a lot more risky because of all the vapours hovering above it. To get it to become volatile enough to burn you have to warm it up until it starts to evaporate. A diesel engine relies on compression effect to heat the diesel until it vapourises and explodes. That's were the bang comes from.

    Which isn't surprising when you remember that the diesel engine was originally invented to burn brewery waste...

    @Graham

    So...

    1. No solid or liquid actually burns. Only vapor burns. So that goes for all liquids, not just diesel.

    2. It is perfectly valid to say that something burns well even though it might take some effort to get going. I will for instance claim that firewood burns rather well.

    3. Petrol engines can't really run on diesel, but diesel engines can run on petrol. However the petrol will no lubricate the diesel pump and thus break the engine. You might get a petrol engine to work with diesel as you say when you have petrol as a primer, but you are really running it on weak petrol and you will clog the spark plug fast. Diesel engines on the other hand are in essence multifuel engines.

    4. Diesel engines does not rely on compression to heat the diesel until it vaporises and explodes. The compression of the diesel is done in the diesel pump and pressed into the engine when the piston is at the top or near the top. The nozzle causes the atomisation and the heat that is caused by the compression of the _air_ in the cylinder ignites it. If you compressed a diesel and air mixture with the piston it would ignite earlier and earlier as the engine heated. You would also need to run it on much lower compression. The compression does not heat the diesel, it heats the air.

    5. The point here was that spraying diesel under pressure onto a fire is maybe not like throwing gasoline on the fire, but still is likely to fuel it.

    Diesel doesn't burn easily ... which is good because the fire would stay localised ... but unless you can tell your diesel from your petrol whilst fire is burning around you it would cause you to panic and cause you to act irrationally :)

    Again my week is complete, Simon glad to have you back is it for good now or will you continue to tease us with long breaks?

    Also why has BOFH not been exposed to 'Project Process' & ITIL more plenty of great material there.

    I think Gate meetings with a twist and a service catalog with 'special items' would fun.

    diesel burns very well...

    ...when hot, or under pressure. It will also burn quite nicely when wicked into cloth, a little like wax will.

    So soak the boss, apply a little flame, and I think the word here is "whumph". Bit like that icon there.

    In the woods (camping) we call diesel...

    By its proper term: "Boy scout fluid". Pour a bit on a stack of wood, and it lights up quite easily. Keeps the soul quite warm when the fire is going strong.

    A finely atomized spray would make a great flame thrower. Then again, isn't that what they used?
