Very simply, I'm looking at making a Babington burner for home heating from used engine oil. I've done a LOT of web reading, but I'm looking for real
world experience.
I'm planning a waste oil burner of about 6 - 10kW has anyone made one, has anyone any real life experience to share please.
Hopefully mine will be an enclosed design! This is for a home not a workshop! NO oil drum technology!watson.fawkes - 21-8-2010 at 11:37

I started to work on one a few
years ago. My only concrete advice is that when you're drilling orifices with 10 mil drills, you need a very solidly clamped setup to avoid breaking
bits. Harbor Freight sells an assortment of micro drills; two of the ten in the package are generally suitable for orifices.Contrabasso - 21-8-2010 at 13:35
I'm considering having three separately blown nozzles! One blown with propane for easy lighting, two blown with air for raw heat power, separately
controlled so that the boiler has three power settings.12AX7 - 22-8-2010 at 16:45
I've made as-cast holes using solder and enameled wire (10 mil ~= 30AWG). Works if it stays cool.

Great idea. You might also try copper plating the soldered holes , with the enameled wire in place to give them strength. and a little more heat
resistance. Using Cerrosafe or Wood's Metal cast around a ball of putty with a fine wire, thread, or fishing filament through it would allow you to
plate around a much smaller hole. Just an idea.Contrabasso - 24-8-2010 at 10:30
Strangely the fine holes pose no problem! I have a friend who has a suitable drilling machine for this size hole and the bits, I also have a contact
at a laser fabrication firm who regularly cut precision holes about this size (but I have to pay them ! ).peach - 8-9-2010 at 02:56
Some people had a go at making these on the hobby_cast forum as an alternative to propane burners for melting aluminium or iron, but it never got past
the yellow stage.
A few possible options for blue flame melting;
Use a vapouriser coil heated by a secondary flame (ala, a DIY turbine fuel coil - Kurt ?Schreckling?, I think you'd like that book Watson)
Bosch make helical vapouriser nozzles for cars. They're essentially a bar with a helix lathed around the circumference that the oil passes through, it
gets heated along the way and then bursts out the tip as an atomised fog.
Use a zeolite filter of epic scale to increase the O2 in the mix.
A pressure washer powered nozzle for fogging? The guys who keep frogs / orchids / grow sheds of mushrooms use something similar, high pressure fogger
nozzles. There's some in the tropical greenhouses at the Kew Royal Botanical gardens. Well worth a visit if you like planties.
Obviously, a monoxide detector is essential if it's yellow and in your home; monoxide, the silent killer.
