[Stoves] flue after burn

Hi All

It seems a bit quiet here.

Now this may be a little off topic for cook stoves but I was passed
this for comment.

It all seems a bit improbable unless there is some sort of catalyst in
the device but even then it must represent a waste of fuel.

The video of it working is shown atop a clay chimney pot that already
has some air entry holes, presumably to prevent back draught in windy
conditions.

Also note the colour of the smoke, it's black initially, suggesting
just adding a bit of secondary air at the fire would have done the
job.
