Flame Speed Video
Alex English, October 6, 2009

This is a very short video which demonstrates the flame holding ability of a hole-in-thin-plate as Andrew described. The video also shows the nature of flame speed. For most of the video the flame is loosely attached to the outside of the combustion chamber. During this time the mix is fuel rich and has a slow flame speed slower than the rate at which it leaves the chamber. Near the end, the flame is able to rush back inside. I can control this with primary air or secondary air adjustments. Primary air controlling the rate of fuel gas production, secondary air supply providing oxygen for combustion and both influencing the resulting mix and its flame speed.

This afternoon I tested a scaled up version of the venturi burner.
The idea being to produce charcoal on a "viable" scale without the
high production of polluting gasses.

Much of this chimney flare was built out of heavy steel because that is what was available. There is no reason why the whole chimney couldn't be made out of sheet metal stove pipe.
