DING ! DING ! DING ! DING!!!!!!
...I think we have a winner !!!!! larry
...1lb of anthracite require a little over 12 lbs of AIR for complete (theoretically) combustion
...which is about 154 CUBIC FEET
..over 60 minutes ( 1 hr) is about 2.5 cubic feet per minute (c.f.m.)
of course this is under perfect conditions..
make up air will vary alot depending on stove type ,coal quality , temperature,humidity, altitude , alignment of the stars , moon phase and shoe size....
....way to much math in this post- love it !!
