Home Foundry Combo LP/Oil Burner

This is a proto-type burner I have been messing around with. It's dual fuel (LP/Waste Oil). It will run on either one without modification. Since it's a proto-type it needs a lot of cleaning up. The final version will have a metal waste oil container mounted to the foundry and the oil feed lines will be permanantly attached. This has been a lot of experimenting with different pressures and configurations. I will say this, waste oil burns a lot hotter than propane. I'm still learning. Stay tuned.

Very very nice design and explaination. What type of "waste oil" are you using. I seem to remember that automotive oils can contain additives that when burned can give off toxic fumes. How do you plan on dealing with it. Keep the videos coming.

@MGARestoration I am using waste oil out of various vehicles. I haven't experienced any negative effects from toxic fumes, nor have I heard of that prior to your comment. I only run it outdoors where there's plenty of ventilation mainly because of the heat generated. Getting the right mixture ratio requires a few minutes of fiddling with the controls and during this time the oil can produce quite a bit of smoke. Once adjusted, it burns pretty clean. I would recommend only using fossil-based oil

Nice set up, I like your forge set up. what did you use to insulate the melting tank?

[quarryone]

The tank walls are 3" thick with 1-1/2" Kaewool insulation and 1-1/2" cast in place refractory.

Thanks for the comment.

nice setup,

i read that if the flames would enter the combustion chamber at a tangent, it will give a swirl at the base of the crucible, using parallel lines to cut the nozzle, or is it unnecessary .

[quarryone]

It does enter the combustion chamber at a tangent for the reason you stated. The final nozzle was cut at a parallel to the inside in the chamber. I hope I understood the question correctly. Thanks for the nice comment.

Are you using a commercial siphon nozzle in there?

put a fire extinguisher nearby

Greetings friend, I can use your idea to connect to a ceramic oven at 1100 degrees temperature rise?Thanks!!

Awesome - loved the way you rode those valves - like watching a musician :)

Any figures for output and fuel consumption?

[SmokeTatum]

Awesome , realy professional work ! 

[MrLeonard55]

Good job.

what exactly is the furnance made from? is it a small boiler of a water heater?
