Look up Silsoe incinerator. The agricultural college did some work

That's interesting, thanks for that.
The two rows of ventilation holes were to try to get it to act as a
gasifier, with a primary and secondary air supply. This burns much
more efficiently and cleanly than a simple fire for lots of reasons
that can be found on the internet.
I've given mine away. One point to watch; don't set one up under
overhanging or nearby trees.
