- Aim: to design a small burner for vegetable oils which does not produce any soot (or VERY little of it).
Hello
I need to design a little burner, fed with vegetable oils like olive, soybean, sunflower and corn (alone or as a mixture).
The fundamental requisite of the burner is that it must not generate any soot (smoke): since "zero" is something hardly attainable in technology, "very little" can be an acceptable substitute
Power output should be in the range 600-800 W approximately.
It should not contain any electrical fuel pump: it must be either gravity- or capillarity-fed. The wick(s), if any, must be non-consuming.
In theory, as I could understand (I am no chemical engineer), there are two ways to burn a fuel with little or no output soot: 1-by an intrinsically soot-free combustion (smokeless flame), or 2-removing in some way the soot generated by a "conventional" flame.
Recently I learned that the problem of attaining a smokeless flame is anything but trivial:
Looks like somebody found the question to be DEFINITELY interesting...
Okay, I don't want to invent Capt. Kirk's antigravity in order to burn olive oil soot-free on Earth
Jokes apart, the first thing that comes to my mind is an electrostatic precipitator of some design (there are quite a few) following a conventional flame on non-consuming wick(s). But the plates of any electrostatic precipitator need to be cleaned periodically. Big installations in industrial chimneys are cleaned automatically by means of high-pressure water, a solution that is ruled out here, for obvious reasons.
Any ideas?...

On board the International Space Station (ISS), astronaut Christina Koch is lighting candles to help scientists back on Earth resolve the long-standing question of why flames in microgravity produce less soot.
