Lump Burn Rate in XL

Condition:  Egg = XL, Lump = Rockwood, Load = 13 lbs, Egg Temp = ~240 deg F, Weather = 15deg low/40 deg high drizzle, Burn Time = 20hrs, Consumed Lump = 7.8 lbs, Lump Left = 5.2 lbs

Burn rate was 0.4lbs/hr

Process:  I completely emptied my XL out.  I cleaned all the ash and removed all the old lump.  I put some big pieces of rockwood carefully on the bottom, worked to place the lump, got tired of doing that and dumped the rest in.  I filled the egg up to the top of the fire ring.  I moved the lump around until my Woo2 and stone would fit on top of the fire ring and not the lump.  I lit a small fire in the center of the lump.

Next I attached my Flame Boss 100 and hit go to 190.  Temp climbed to 300, fought with that for 2 hours, finally realized the copious amount of foil I used around my wires was keeping the lid slightly propped open and I could actually see into it from around the dome/base intersection.  Well no duh I couldn't cool it off.  I fixed that and the temp began to drop.  When it hit 280 I put on a 9.5 lb brisket.  Temp ramped down to 240 and stayed there for the duration of the cook, except for a minor ramp of 30 minutes at the end.

The weather over night was cold, it began to rain around 9am the next day and drizzled on and off till i pulled at 5:45PM.  At that point I capped the Egg and shut it down.  Total burn time was 20hours.

I removed all the lump left and weighed it.  I had 5.2 lbs left.  So I could have gone for another 10 hours or so.

Side notes, I weighed all the bags of Rockwood I had and @stlcharcoal might want to retrain his guys.  They loaded exactly 21 lbs in all 6 bags I have, even though I only bought 20lb bags  ! I guess I can forgive the occasional pebble I have come across

Also, when your wife asks why you are bringing the scale to the garage it is best not to answer.  When your neighbors ask why you loaded all the used lump into grocery bags, again it is best not to answer.  People might get the wrong idea and begin to think you are crazy.
