Bricks in the chamber??

[williamzanTzinger]

Well, after being patient yesterday I was readdy for a full load in my new charbroil. I did some ribs, a chuckie and some abts. Getting temps where I wanted them was doable. I used some bricks to try and control the convection of the heat through the box.The bricks in the middle help to usher the strong heat to the left and right and fill the chamber a bit more evenly. The ones on the end were meant to reduce the excess space on that side of the chamber in hopes of concentrating the convection toward the grill on that side. After a couple of hours they heat up adding to rebound in the chamber after mopping. The last mod I made, or found by accident really. I had like a 3 foot piece of dryer exaust laying around, I put it on the chimney (outside the box) and the temps in the chamber climbed, playing around I removed it and the temps dropped. Were talking like 7 degrees or so but still. I guess the longer pipe slows down the draw??
The pice were of the chamber at one point when the right side without the firebox was actually hotter than the fire box side. Found that notable.



only food pic I snapped was the ribs(sorry) I was running late.

Beauty eh! If the FB side lower than the other becomes an issue, just open up a couple of the FB side baffle holes.

You will have that pit talking to ya in no time :{)

I would think the longer stack would increase the air flow, but hardly an expert on the subject. I'm going to try that with my Charbroil Silver and see what gives.

Nice experiment...how did you put the dryer vent on the exhaust? That will make a difference if it continued straight up or curved down and then back up or just went down.....all that will affect the draw

I'm with you. To a certain length and if it was straight, the hot air rising out of the stack would create more draft and suck more combustion air in.

That's why the old wood fired boiler stacks were so tall -- or that's what the old time boiler operators told me anyways.

I had it bentaway from the wind as it was windy that day. The increased flow would acount for more convection I suppose, and if the bricks to the side do in fact help the convection move upward toward the chimney that would explain the temp spike on the right hand side. I know im over thinking this, but, thats what we do no?
