Propane burner for my DIY foundry

I’ve decided to build a small foundry. I designed & built this burner, in my home shop, based on what I’ve seen on you tube.

Nice design. I would like to see what it does with a blower hooked up to it.
What pressure are you running?
@earlyhemibill
I warm up with 18-20 PSI which takes about 20 min (for aluminum)
once it’s running, i can back it off to about 10 psi
It burns a bit too rich on your vid. Try to add a choke at the venturi.
Otherwise, nice design !
it looks professional!
@jameasun: I did experiment while testing, by assisting the air intake with a blow dryer. This disrupted the airflow quite a bit and often blow out the flame. I also tried choking it, and it also dramatically affected the flame. While mounted to the test post, i could only crank it up to about 45psi before it would blow the flame out. Once running (at temperature) inside the furnace, this wasn’t a problem.
