These air pockets inside have a small pinhole size exit holes. When they're lit, the air inside heats up and squirts out of the small hole blowing on the briquette next to it.
Not for long but perhaps long enough get get a small spot on the adjacent briquette lit.
Assuming they were pre-infused
with starter fluid, you'd just throw a match on, in a few seconds the whole thing would start hissing as the air escaped and you'd have enough charcoal lit for the rest of the process to sustain itself.
Funny, I just brought in dinner from the barbecue when I saw this..

Put these inside the briquettes... [normzone, Dec 01 2011]

Since the amount of gas released is small, better it
should be pure O_2. Or add to the briquette some
substance which releases oxygen when it (thermally)
decomposes. Potassium permanganate maybe? |
|
| |
... and: //Utilizes// Eww. What's wrong with "Uses?"
Mother bloody tongue is going to the demnition
bow-wows. |
|
| |
True, there's not a lot of O2 in there but there might be some cumulative effect of all those things blowing at one time. |
|
| |
I don't think there would be enough volume to make
a difference. |
|
| |
Maybe the oxygen in deeper pockets could be pressurized before production was over. |
|
| |
Yea, but the air inside would still rather go out of that hole first. It's the path of least resistance. |
|
| |
Note: if you mix oxidizer and charcoal, what you
have made is solid rocket fuel. You will have a very,
very cooked meal. |
|
| |
Well, it could be a very low ratio of oxidiser to
charcoal, couldn't it? If we don't get the proportion
quite
right, it'll still
be marketable to the demographic that pours an
entire can of lighter fluid on the grill. |
|
| |
//But how do you get the air to become trapped in the briquette to begin with?// |
|
| |
Just cast a hollow briquette by having two concave sides that you glue together with more liquid briquette mixture. Leave a pinhole in one side. Voila. |
|
| |
Believe it or not I'm very familiar with the oxygen barbeque link. One of my favorites, I've watched it several times. If you've never played with liquid oxygen and fire before I would highly recommend it. |

// Or add to the briquette some substance which releases oxygen when it (thermally) decomposes.// Baked by Benjamin Thompson in the late 1700s; he devised fuel pellets comprising charcoal, clay, and potassium nitrate. |

You know, I'm curious why that hasn't caught on.
Just have an edge of the briquette be made of some
form of solid rocket fuel that's self oxidizing and
burns hot enough to get the coal going. |
|
| |
Maybe you get into shipping issues with friction
during movement causing the whole bag to ignite or
something. |

I hereby say "Thermite!". |
