Drew, thanks for the writeup on your flare burner.  In this particular
case, having the photos on hand while reading your description was
pretty essential.

I thought that your primary air adjustment was a pretty slick idea.

Is there a reason you chose to point the flare downwards, rather than
upwards?

I see some set screws on your outlet just prior to the flare, is there
anything inside the 1.5" pipe other than the sheet metal flameholder
ring you mentioned (e.g. throats, mixers etc), or is what we see on the
outside pretty much it?  Any interior area restriction near the gas/air
mixing point?

Any photos or details on your gasifier?  Is it a positive pressure
setup, or is it actually pressurized (i.e. several or more psi)?  What
do you use for pressurizing/blowing it?

You use your gasifier for forging, right?  How does its performance
compare using propane, and coal?  What do you use for fuel (and what is
its m.c.)?

Cheers,
