Can't re-light briquettes.

[Mosca]

I've been BGE for 7 years now, and I'm used to killing the fire and relighting unburnt lump for the next cook.

With the Weber, I kill the fire... but when I fill the chimney for the next cook with the partially burned briquettes (the ones that don't turn to dust while handling), they pretty much sit there and do nothing. Or very little. They glow somewhat, but I wouldn't use them for cooking anything. I've mixed them in with fresh briquettes, but they act more like filler than fuel.

So that's all I have to say. I've discovered that there's really no point to trying to relight briquettes. Dump 'em, refresh, and move on.

I never use old briquettes. I only use new every time. Do you store the lump overnight in the BGE? Briquettes in the kettle? The BGE keeps moisture out and the kettle does not.

thats all I got and I was reaching.

I reuse briquettes all the time. I just top off with new ones. They don't last as long so I may pull them out if I'm doing a long cook, but for short cooks I reuse. You have to make sure they are not damp though.

I save up my partially used briquettes until I have enough to completely fill a chimney and use that as a base for my LSG before placing splits on.
They do take a long time to get rolling though. I think in part because there is much less air gappage in between the now smaller coals..
Is gappage even a word.

Now that is a creating way of reusing them.

I reuse briqs all the time, but a chimney full will take a loooong time to get fully lit. I also use them for shorter long cooks.

[Buck Flicks]

I usually use fresh briqs to start the fire, then throw the lit chimney on top of the used briqs. I don't use them for smoking - just hot grilling.

I don't bother with trying to reuse briquettes anymore. There typically isn't a lot left, and I pretty much never pay more than half price by buying on sale around holidays. I just let it burn the rest of the way out at the end of a cook.

[Troutman]

I made some real tasty burnt ends with mine ...

[Spinaker]

Another reason I prefer lump. I only use briquettes in the PBC, and I never relight them because they don't burn well the second time around. It is much easier and more consistent to load it up with fresh briquettes.

And the Kingsford original is so damn cheap, why the hell not! $9.88 for the twin 18.6lb packs over Labor Day at Lowe's. I mean it's probably cheaper than running the electric oven!

Well, I've never used partial briquettes till now - I put a gasket in my Weber 22, and whatever was left is still there and dry the next day.

If it's not a moisture issue then a fan might be a worthy investment. Here's a recent cook I did in a fan controlled PK360 with a mix of used KBB and Weber briq's with a little lump. It was a hot/fast cook with a target of 350.

The temp stayed above 325 for 2.5 hrs (long enough to cook a Turkey.) I'm using two Weber charcoal baskets here with two fire starters - one placed in each corner.

In the chart the temp dropped twice : when placing & removing the meat. In the last image I placed all the glowing coals remaining into one basket and it held at 250 degrees (at that point the cook was done, the rest was just for curiosity.)

The fan had to work hard - especially at the beginning & end. Doubtful that I'd have the same results without a fan.
