Can a firebox get to much air?

[bigsmoken]

So I am building a grill right now and I have this question. I am ready to build the firebox and designed it with a slope at the bottom and a one inch hole running the front of the firebox for two reasons. One it will allow the ash to fall out of the fb so that way I dont have to worry about that and it serves as a air intake. My question is if I put a steeper slope on it the ash can fall easier but then it puts the one inch hole to a two inch hole. That makes it 28 sqin to 56 sqin on the air intake. I was wondering if its possible to give a fire to much air.

If you have dampers, all you need to worry about is having a large enough opening to supply the maximum required......

now you told me that I needed at least 21 squinches of air intake. can I dampen that? or does that need to be open all the time?

Use an adjustable damper on the inlet air.....  that way you can control the air and the heat to the CC,,,   A second air inlet directly across from the FB/CC opening will help the temp control and fuel usage also....
