Vertical Wood Stacking

Cold heater (50 hrs).
Some very large pieces, that had accumulated.
Large load of wood - 70 to 80 lbs.

Stacking (poor photo). Notice the gap in the middle of the pile.

This gap is filled with kindling.
The kindling is ignited at the bottom with a torch.
The loading door is left cracked open.

3 minutes
Note that with the extra air, the vertical kindling in the hollow space acts a bit like a rocket stove. There is a quick ignition, and a jet of flames shooting out the top of the pile.

View towards the top.
