Here is a series of pictures showing how we get a good start in the pyramid kiln by stacking a pile of wood in the kiln and lighting it from the top. It burns down to coals pretty quickly and gets the burn off to a good start by providing a nice, deep bed of coals that can really put out the heat for the first layer of wood.
We call a pyramid, cone, pit or tube an Open Fire Kiln.
We call an open burn pile that you light from the top (so it burns up the smoke and is clean) a Top-Lit Open Burn. You can read my article about open burning of forest fuel load reduction piles here:
Learning to Burn and Make Biochar, Not Smoke. Kelpie Wilson. Tree Care Industry Magazine. February 2014.
Build an open stack of wood with kindling on top. Light the top.
Heat transfers by radiation to the layer of wood below the flame.
Most of the wood in the stack is now charred. It only took about 15 minutes.
All the wood from the stack is now charred, and the pile has collapsed.
Now we have added the first layer on the bed of coals. We will continue adding a new layer as the old one chars.
