[TheForge] propane forge

[Jerry Frost]

Morning Bob:

Sorry for the slow reply but I went back to my paycheck job after taking a
week off to drive and cook for a visiting friend. I'm back to heading off
for work at 5:00 am. getting home around 6:00 pm. and not checking E-mail
till my weekend. The upside to these hours is a 4 day work week. <grin>

Anyway, the following URL shows the T-Rex burner and has links to Rex's
pages. If you click on the image to enlarge it you can see an excellent
example of a home made jet ejector type burner. Notice the tube is threaded
pipe with wide slots machined in the side and the back end capped. The
primary gas jet is inserted through the end cap. The wide slots in the side
are the air intakes. The sliding choke is for adjusting the burn ratio.

If you draw a line straight up the bore to the jet and more lines straight
in the air intakes, you'll see the 90* relation I was speaking of. Once
again, I have to admit I have no idea why positioning the intakes at 90*
should make so dramatic a difference in efficiency over a linear arrangement
but it does.
