Anybody have any updates on the oil burning forge.I know some of you have built one any advice and help building one...

Thanks,
Bruce
 
It does look promising. I got the book from Colin Peck, "The Artful Bodger's Iron Casting Waste Oil Furnace" It goes over a lot of stuff regarding waste oil use. I am hoping to adapt it to a hybrid LPG/Waste oil system. Just need to find the time.
 
Bruce, only you can answer if it's worth your time....

If you have access to lots of free waste fryer oil or waste motor oil, then it could be worth your time.

The burner isn't hard to make and if you don't like it just make another burner.

Thanks guys,Willm I know it will be worth it,just lost all my links and was wondering how they were working for you guys.

My forge is working great when I have time to fire it up. I've noticed there is some sort of "crud" build up in the bottom (it's a vertical body) so make the top removable and I have a chunk of steel plate in the bottom of the forge I pull out and just bang to remove the "crud". I need to get some sides on my forge area cause when it gets really windy it causes some mixture problems.

I tried using waste fryer oil but have quit because of competition from the biodiesel guys. Noone wants used motor oil so I'm getting that for the forge.

The burner is a 17" x 1 1/2 tube with a 1/8 oil feed tube that enters the burner body at a 45 degree angle about 3" from the end of the burner tube. The oil feed tube is cut at a 45 degree so it's parrallel to the bottom of the burner. Fan is on the other end of the burner.
 
The changes to the forge was to make the top removable (that includes the lining and coating) and to put a steel plate on the floor to make clean up easier.

If I was in a cold climate I would probably work some sort of pre-heater to keep the oil flowing at lower temps, I don't really have any idea if that would be necessary once it gets up and running.

I've read where people are using chunks of wood and I used to use a piece of charcoal in the forge body to get it going initially. Now I just put in some cardboard and let it rip. I've been told by "experts" that the way I run my forge doesn't work. I dunno, I'm not an expert just a redneck.

I'm happy to answer anything but frankly since it works I don't spend a lot of time wondering how it works.

That was awsome! My wife heard me laughing, I lost some hair also from my initial learning building a propane forge.

I wonder if you ran the oil directly into the line that the air pushes through with something like a spray/shower type nozzle to improve air fuel mixture for the oil?

Or maybe use oil type injuction by applying pressure to the back of the oil pushing it to spray?

Just think out loud.
 
I have the oil gravity fed into my burner tube. It drips and the blower fan mists it, when the burner comes up to temp I guess it vaporizes the oil as it feeds in. Kinda like the old diesel tent heaters we used to use in the old Army. I use a needle valve to control the oil feed and a gate valve to control the air flow.

Don't make it too complicated and it'll probably work.

Edited to add:

From watching the video, the flareup is caused by too much oil being dumped into the hot forge body. The smoke is from the mixture being too rich. I only get smoke when I start the forge and if I don't leave the blower running when I shut it off.

Oil forges are really economical, I probably burn 1 gallon for about 2 hours of forging.

Will,
How much air are you pushing? Does it sound like the one on the video?? I am hoping it can be done with a quieter set up.

Mine sounds a lot like a jet fighter but I'm running 1 1/2" burner tube, no idea of what size blower motor. I don't think it's any worse than any other forced air forge I've been around.

I like the sound though....
