It gets a bit technical at this point and you must remember I'm just a Truck Driver who burns coal.
From my understanding the Gases escape the 1000F bed of coal you reference because at that point the oxygen needed is being consumed by the primary combustion (1000F bed of coal) which is why the damper is beneficial in reducing the volume of the flow so the gases have a chance to oxygenate (scientific part) and combust and I am told that while a flame as we know it to see it may not exist the gases are indeed burning .
I buy in to this idea because with my Victory stove if I sit and watch it I will often see little blue wiffs moving across the coal bed and around the edges of the fire box also if conditions in the stove are just right I can open the feed hatch on the top of the stove and the entire stove fills with the prettiest blue fireball that just sort of swirls around inside for a fraction of a second.
