Taken to demonstrate the lack of visible emissions from my waste oil heater.

I am struggling to get a variation of the mother earth heater going. My main difficulty is regulating the oil flow and keeping temp high enough. Any chance you could send me some details of how yours is constructed . I run on vehicle oil.

@jwo388 You are going to have troubles as the ME heater seems to have a lot of problems.

Just watch my movies and look at the website listed at the end. There's far too much to type out every few days.

Why are people so concerned with emissions?? The waste oil is certainly a thousand times more polluting as a liquid. Most of the the exhaust is CO2 and that's good for plants, allowing them to produce O2 and the rest will be carbon which is what people and everything else is made of. Nothing worse than someone with a little knowledge.......

@lumberjak5010 Everything we do in this world is a trade off. Just the fact that we are here causes pollution and we use the worlds resources, the trick is to get the best from what we have to work with. The pollutants in oil are there, and they never disappear they are merely disipated to other places, even re refining the oil is merely away of removing most of the pollutantsand concentrating them into another waste product that has to be disposed of.

I love the fact that there is NO electricity involved. It is a stand alone unit.

Yep, it may be a little deeper but you don't want it too deep as the flames from the primary air inlets must sweep down across the top of the oil to provide the initial heat when lighting up

Disregard the question I asked on the other video. It appears in another video that the secondary burner does not go down into the camp stove so it must be the lid that's about 4" above the oil vaporizing surface.  A 4" deep camp stove I get it.

[ozzirt]

The camp oven is 12" diameter.

You must ensure that the primary burn is oxygen deficient to ensure that the vapour is oil and carbon rich, so that when the secondary air hits it, it burns hot and clean. The downward radiated heat provides much of the heat helping to vaporise the oil in the pan, but it must only be about 4" or so above the oil surface for maximum effect.

[yonmoore]

So that secondary burner keeps the pot hot enough to vaporize the oil then? And it looks like you're using the smallest camp pot they make right? Like an 8"?

Sure wish I would have discovered your design before I built that other heater. Oh well I had fun doing it! I'll play with a secondary burner and see if I can get it going. Thanks.

The secondary burner is most definitely the secret, the primary burner is only hot enough to vaporise the oil in an oxygen deficient atmosphere. When that hot gas is mixed into the secondary air stream, that is where the heat really occurs. It is important to gave a good draft and all seals and joints to be as close to airtight as you can make them.

The secondary holes must provide enough air and also plenty of turbulence to effectively mix the air and hot gas.
