Metal Casting at Home Part 90, Waste Oil Burner Part 1

My furnace burner has been redesigned for simpler construction and easier dismantling. My original used a Hago siphon nozzle that I had to import from the US. The shipping, custom charges and VAT on the import meant the part cost around £65.
The new design uses a nozzle that was £12 including world wide delivery.
1.0 mm nozzle: bit.ly/2RtjQpC
Parts were printed on a Sovol SV01 printer : sovol3d.com?sca_ref=895359.hScoXg1y01
Copper tube and 2" stainless steel exhaust repair tube came from Ebay sellers.
I have uploaded the STL file here www.thingiverse.com/thing:403...
Burner is good for waste oil, vegetable oil, kerosene, etc.

I have tried a lot of the DIY waste oil burner designs, but I have had mixed results. I built this one and did a test run yesterday--simply amazing. I did have to pre-heat my oil, but it was incredible how easy it was to light. I'm not good at soldering, so I had to build it with compression fittings. I used a male to male street elbow for the oil inlet on the top. I had to cut the threads down a little on the side going into the nozzle so everything would fit in the stainless pipe, but it does fit. I love that the design is modular. I can pull the whole stainless pipe out if I need to clean the nozzle on the burner or make any adjustments. Now I need to track down (or make) a variable speed blower like yours and I'll be set!

[@myfordboy]

Thanks for the feedback, glad to hear it works for you. I have my fuel tank about 5ft high and find no pre heat oil is needed although if the air temp is below about 15C I warm it to make it flow better, this is for waste motor oil.

I have some lovely 8mm thick 80mm pipe i'll use for the burn/mix chamber - much more durable and easier to weld etc. If it wasnt for the fact i have an ancient air compressor i'd be tempted to go back to the siphon nozzles! great vid as always.

We have basically the same set up except I'm using 2.5" 304ss. And my air hose uses standard coupling so i just plug it in straight from the compressor.

Hello from Seattle WA! Another terrific video and one that I'm going to follow this weekend. Since I'll be moving from AL to Iron I'm assuming this is the burner you use with Waste Oil for your Iron castings, correct? Quick question... I'm surprised that the silver solder doesn't melt or eventually break down since its at the very business end of the burner. Obviously it doesn't get hot enough at that location, but just out of curiosity how is that possible? Thanks so much for all you do! your experience and guidance is so very appreciated! Best, Bob

[@myfordboy]

No problem using silver solder inside the burner. It would have to reach near to the meting point of the brass nozzle to melt. Inside the burner tube it is cooled by the blower air too.This burner will melt iron.

[@markamy357]

Excellent, I have noticed how affordable these Chinese waste oil nozzles have become too, like you I acquired an expensive nozzle but can only melt iron in my furnace just like yours using the Artful Badgers waste oil nozzle which partly preburns some of the oil before it enters the furnace proper. Will you size your nozzle to melt iron? It should be interesting to see your furnace do that.

[@myfordboy]

I can melt iron OK with the nozzle I have, This Chinese one is identical internally to the expensive Hago one. I can pre heat my oil as the oil tank sits on a single ring electric ring.

@@myfordboy My nozzle burns 3 US gallons per hour (500,000 BTU). The pressure regulator sprays # 2 fuel oil at 100 psi to the nozzle. One can turn that pressure up if need be. The 100 psi is the standard setting from Beckett. One selects the nozzle and flame retention plate from the Beckett catalog for a given btu yield value. Both the fuel pressure and the air intake damper are adjustable. On my last test firing I went from stone cold to 10# of melted aluminum in 30 minutes flat. I haven't tried bronze or cast iron yet.

​@@myfordboy Thanks, I'll test like that, mine was about 50 to 60mm behind the end of the tube and I wasn't getting flame sustentation and when I do, there was too much smoke and unburned oil dripping.

Thread joining compound called Heldite. In fact one joint leaked a little so PTFE tape was used as well.

What's a "typist", and where can I get one?

[@myfordboy]

You need a time machine and travel back to the 70s.

I have done the same burner, 1.0 chinese nozzle. Outside furnace I can burn only kerosene or diesel, but waste oil or veg oil do not burn. (I can burn the only if pre heat more than 120°C . Where I do wrong?

[@myfordboy]

I have not tried to burn waste oil with the burner not in the furnace. I have my waste oil tank mounted about 5ft above the burner to give some pressure to the oil in cold weather I heat the oil to about 40C. With kerocene the fuel tank can be at floor level and the nozzle will syphon the fuel but it does not work for waste oil.

[@ivanogennero5056]

Ta! for quick answer. I haven't tried to elevate the oil tank because I see that the oil is sucked well from nozzle. Today I'll try. I will also try to put the burner intote furnace. I'll let yo know.

[@ivanogennero5056]

@@myfordboy I solved. Thank you for right support. I mount the oil tank 1mt above the burner, change the tube form ID 6mm to ID 8mm (to achive more flux) and warm the oil to 35-40°C and I put the burner into the furnace and itworks perfectly on the first try. I see that it needs only a very little air flow from blower to have a good flame. Is it correct?

[@myfordboy]

The amount of air needed would probably depend on the furnace design. Just adjust the air flow to achive a good flame. ^mm pipe was a bit small mine is bigger, maybe 10mm, sorry I forgot to mention that. A lot of waste oil burner uses have to start with propane or keroscene and switch to oil when the furnace is hot. I have never found this necessary.

[@ivanogennero5056]

@@myfordboy Are the internal burner's pipe also 10 mm? For internal burner's pipes I use ID 6mm for air, ID 8mm for oil (up to needle valve) and 10mm rubber tube from needle valve and oil tank. My furnace is the exact copy of yours, and works like a charm ! :)

[@12prasad21]

Why do you not use ferrule connectors that can be crimped on to the pipes. And avoid soldering ? Know for a fact that such connections work well.

[@myfordboy]

Not enough room inside the pipe to used compression fittings.

I have the machine he describes so no need to build one.

why go through all that when you could get the burner from an oil furnace that will put out twice the heat and will burn any oil including kerosine

How do you filter your oil ? I don't care much for that design be OK for a clean kerosene or diesel fuel but not a waste oil ,sorry

You are the expert.

What about check valves? No need of one?

No and in a later update I have done away with the air valve and replaced the needle valve with a ball valve.
