Someone explain to me how spontaneous combustion works.

Spontaneous combustion from what I've learned (I've learned this from word of mouth, plus I don't exactly expect you to trust me, being anon and all) is when your body excretes a high enough amount of combustible gas that anything that would set off a flame would do so. Except on you. So say for example, put a lit lighter near your ear, just warmth, right? Well if you had spontaneous combustion your head would be set ablaze. Worst part is it's mostly set off by friction so any rough sex it wrecked when you or your lover are now both on fire. Unless you're into that. THat also works.

TL;DR Your body leaks gas that's very sensitive to heat or friction, hence why you're suddenly aflame at random times.

firefighter here,
as faithrider said, combustion requires 3 things, heat source, oxygen, and fuel. in this case your body and clothes would be the fuel. for spontaneous combustion to occur, you body would have to reach its "flashpoint" or "heat of ignition" within a short period of time. flesh has a high moisture content, so it would boil long before it would actually catch flame; more than likely your clothes would combust first.

Science time
solids and liquids DO NOT BURN, they must first become a gas. the process of solids or liquids becoming a fuel gas is called pyrolysis. For this to happen, the fuel (in this case cotton) would have to be heated to 410 degrees Fahrenheit or 210 Celsius to combust. so essentially your clothes would have to hit 410 Fahrenheit in a few seconds for this to occur, which is next to impossible outside of laboratory conditions.

TL;DR clothes hit 410 degrees and you get toasty.

they must be heated to their point of ignition and become a gas in order to combine with oxygen during combustion. I really cant simplify it much more. google "pyrolysis"

I think he's saying that with enough heat liquids evaporate into gas and solids sublimate into gas, which when ignited becomes the real fuel source of the fire... which would in turn convert more of the solid/liquid into gas which would keep the fire alive. just speculating from what he said. that's how my brain is explaining it to me.

You combust spontaneously.
You combust spontaneously.

the few reported cases are either too old to have evidence, or have a lack of evidence to prove it was spontaneous.

Not the outcome.

because combustion requires three things- heat (or ignition), oxygen, and a fuel source, spontaneous combustion is impossible. this is because you can't just throw the three together, it has to be a certain mix of the three. think about a car engine.the combustion doesn't take place as soon as the fuel enters the chamber, it ignites when the solution is at the optimum mixture.
