The power of ash....

  1. What difference knocking a bit of ash off the coals can make. Cooking my overnight brisket at a stable 234° since about 9:00pm. Thought I'd knock the ash off before I get another beer. Just tapped the bottom of the WSM with my foot two times. Temp went from 234 to 255° in 2 minutes.

    I have it settled back into 240° but I thought that was pretty wild.

    Interesting tjs ! Sounds like the ash maybe works as a insulator ! Makes sense I think.... :biggrin:

    Ash build up chokes off oxygen to the heat source. By removing the ash your charcoal/lump was getting more oxygen and burned hotter.

    Charcoal, especially briquettes, burn from the outside in.  The ash definitely works as an air insulator.  Knock it off, new outside exposed to the air!
  5. I have often thought about building a "knocker" for a small smoker to keep the coals ash free.  An electric solenoid which taps a plate on the side of the smoker a few times every 20 minutes.  (Honey, is someone at the door again? I am getting tired of these kids knocking and running away when you are smoking).

    Before I got my BBQ guru my WSM got a couple of light kicks every 3 or 4 hours. Using the guru burns the charcoal down to nothing without any outside help.
