Looks to me like all you're doing is burning wood.

I guess that's as good a description as any I've heard. LOL

Need more secondary air and reduced primary air.

I made one of these too and had the same trouble. kind of lost interest in this after

I've found that there is a best fill level. my guess for your super stove would be 3cm below the centerline of the top holes.

The reason it needed the fan on to stay aflame is oxygenation. Too much of the wood gases at once chokes it out, like flooding a car's engine with fuel.
