Is this useful?

At a half million btu's you should be able to weld 2 55 gallon drums together and make a really big forge ;0)
 
There's been a few waste oil burner forge builds. The only concern is cost of repair I'd the burner has a bad part.

Look up oil fired forges and you'll get some ideas.

You know you wanna build a drum forge!!
 
No, I don't. Will this be able to beat the cost of running a little propane forge? I have access to farm diesel.
 
It isn't for a small forge...or really for a forge at all. It is the burner and control for an oil burner heating system. It isn't designed for high temperature as much as it is for total BTU output.

You would have to make a very large chamber forge with good insulation and a fire brick liner (It will need both).
If you are going into commercial damascus production, it might be useful, if not, the only useful part might be the blower.

What I would do with that is clean it up well and check it out to assure it is operational. Then sell it on ebay and use the money to build a 8X16knife making forge with a PID control.
 
I like the sell idea. I already have the forge, so it would probably end up going to a 100 lb tank and some refills.
 
This brings something up I might be able to contribute. sorry for the tangent.

How many guys here use old oil burners for their forge? I have what is relatively tons of old oil burner data on fuel flow rates, and oriffice sizes as they relate to heat output.

If that is something folks could call direrctly useful in backyard forge building I can try to dig them up. Gilbarco, Burnham, Sunray, Carlin, Econojet, Warco, Texaco Fuel Chief, burners, and assorted nozzle details.
 
If I was to create a waste oil burner, it would use used french fry oil, not motor oil.

There are huge carbon and crap particles in that oil

The burner design I saw used an oil drip into the airstream.
I like that for it's simplicity/

I think real spray nozzles would clog very quickly.
 
I have seen several waste oil burners. They all burned fryer oil and cooking oil.

They are just regular propane forced air burners with a 1/4" fitting added to the burner tube. It needs to be close enough to the flare so the tube is hot at that point. The storage tank for the oil is placed at a height above the forge to allow gravity feed. There is usually a filter screen in the line. 1/4" copper tubing is used to connect the tank and the burner.

Once the burner is running on propane and the chamber is heated up, the propane is reduced and the oil is allowed to drip by gravity by opening a needle valve to allow the oil to drip into the hot burner tube. As it drips onto the hot insides of the burner tube, it vaporizes and then gets atomized in the air blast, the propane can be reduced as the oil is increased to the point where the forge is running on oil alone.

There may be some by-products of the oil burning that are bad for you, so I would recommend you do this outdoors with good ventilation. Motor oil should NOT be burned in one of these burners. Cooking oil can be had for free from many places, and should be screened for debris before using.

A self contained oil burner like this thread is about will not really be needed.
 
I got an old Warco oil burner myself for free a while back; it's a cool thing but as Stacy says I might just pillage it for the good blower and junk the rest. I do have a waste oil forge, but the veggie oil I run in it is too high in viscosity and impurity to work with the Warco burner. I just use a drip system as described above.
