after trying to get the bit together for my beckett style burner and failing miserably, i decided to start up my babington project once more (id dismantled it all and was ready to skip it), well put it together again and started it up it lit easily after i warmed the oil for 30ish seconds with the glow/heater plug and threw out plenty heat no smoke or smells,
Now im not using a pump to move the oil, ive made a sump at the same height as a piece of capped off pipe and connected it with some 2" box section, now as long as i keep an accurate level in the sump the capped pipe level stays the same, then ive submerged a brass dome headed nut with a 0.03mm hole and hooked up an air compressor, my workshop floor will never rot as i slop oil all over the place (messy worker), ive a few adjustments and then i will get onto harnessing all the heat, i think a propane tank will do to house the burner and then another with a gap to allow me to have a fan running to blow the air round the workshop i will try to put a pick up to show you guys the idea, and maybe some vids of it running

This looks promising...do you have any pictures that would allow me to visualize this a bit better?
Also since I am new to this could you detail the "burner" and nozzle a bit better please?
Thanks so much for the help.

hi there its quite difficult to explain it in depth due to the way i see it but i will try.... here goes....
Imagine having 2 containers 1 filled with oil the other empty on a table side by side....
(http://i190.photobucket.com/albums/z222/nasty-nik/table.jpg)
right now if i put a pipe between the two containers.......
(http://i190.photobucket.com/albums/z222/nasty-nik/table1.jpg)
the oil will flow untill it is equal on both sides
(http://i190.photobucket.com/albums/z222/nasty-nik/table2.jpg)
so we use this to maintain a constant level in our smaller burner tube,the sump as you will see hold lots more oil than the burner tube so the level take a long time to change, and the ball cock keeps this level constant, much like the level of water in a toilet cistern...
ok now the burner
the oil level is kept contantly 1 mm ove the top of the dome headed nut (you could use a brass doorknob or anything smooth and with a curve this lets the oil cover the hole easily once the oil have been atomised and blown up in the burner tube...(http://i190.photobucket.com/albums/z222/nasty-nik/oillevel.jpg)

so we have the oil level 1mm over the top of the nut, now this once blown up into the air is not enough to promote a flammable mixture, because the oil is cold it will spit and shoot blobs of oil instead of a fine mist, so we have to heat the oil, i use a glowplug from a diesel car, but a 110v/240v heater would probably be easier, it only need to be a small heater like 150w as the hot oil rises up, then turn on the air, light with a blowtorch and your away, turn off the heater after about 1-2 minutes as the flame will warm the oil, you will do well to let the atomised fuel up a tube with holes to let the flames out and air in, as long as the oil level remains constant and the air is 30psi, it will continue to burn forever i suppose, no soot and no cleaning as its fantastically clean burn with no smoke just heat waves, if you have anymore pictures or have anymore questions i will try to help, cheers

Had it running the other night, and the pipe with all the holes in it glows after about half an hour, and still no smoke but then all of a sudden, we had flames shooting from everywhere ??? >:(, the oil around the domeheaded nut had caught fire due to the heat and it cocked up the atomisation i had going so i reckon a large washer over the oil, with the hole above the domeheaded nut should cure it. does anyone else play with babingtons? as its kinda lonely talking to myself i here

Keep talking, I'm listening.

for some of you that have not seen much of the babington design here is a link to a good clip on how to make a basic babington burner

Tightwad I haven't played with the babington heater but I have another idea. Tell me, did you really make a 0.03mm hole or just a 0.3mm ?
-
hi yes i used a tiny hole, 0.03mm, or you'll be using air too quickly

Fridge compressor is a nasty little thing. I have a pressure gauge which can measure to 145 PSI. But the gauge is not strong enough. The compressor gives a lot more than my gauge can display, and as you can see on my video, i have enough air with a 0.6 mm hole. Unfortunately, I couldn't find a drill smaller than 0.6 mm in any shop.
-
I have some measurements. 1 bar = 14.5 psi
1. fridge compressor off
2. compressor on. Needle is made a full circle.
3. pressure with 0.8 mm. hole
4. pressure with 0.6 mm. hole
So, lowering the hole for 0.2mm, pressure raises for 1. I think that ideal hole for my new project is around 0.3 mm. With hole these size, i have enough pressure and enough air volume for atomizing oil. Only with fridge compressor without air tank. :)

Tightwad, like you said a few posts ago ..... its kinda lonely talking to myself
Seems to me that this forum is dead.

Not dead Moov just lots of read only posters. I enjoy your posts as I learn from your work ;D.
I see you use a frige compressor to pump the air, be aware that this type compressor gets its oil from the refrigerant it is ment to be pumping, if its a hermetic compressor it will die a very early life without oil getting added on a regular basis. Try to add an air line oiler to the intake if you can get one.
The only way to check most small hermetics oil level is to turn them upside down then measure what comes out and put it back in plus what was low.

Why am I on this forum .... I made a lot of different types of heating across the years of my dealing with waste motor oil, and in time it became my hobby. Problems of clean combustion and adequate quantities of heat are long behind me, and i am on this forum because I hoped that I would by talking with others, gather ideas for the burner which I said to myself .... 'That's it, better burner can not be made'
I put two videos on YouTube in the hope of running some sort of discussion, but nothing happens. Instead of talking with others, i write to myself. And for that i not need the forum.
This is my last post. Goodbye everyone

Moov,
Sorry to see you go. As a beginer to oil burning I was hoping to learn from a person like yourself that has had the experience. I also understand that there's not much going on here.

Moov, sorry to see you go. I would like to see you stay around. Your help has been much appricated on here.
I am sure that in due time a new idea will surface from this forum that may intrigue you.
