Just place the pot burner below the heat riser and ensure enough air flow. Starting with the heat riser the applied physics will be the same, thus everything can stay the same from this point. This burner design has proven successful If a fuel will be worthy depends mainly on an inexpensive reliable supply. The energy-density of oil is much higher than of wood. It is far easier to implement an automatic feeder than it is for wood.

A rocket stove would need a down draft air supply as well as the regular air supply, the fire could be started with wood as usual and then drip the oil, I will post the drip system next

Here is what a drip system would look like and see the stove as to how it would be driped into the burner

I look after oil burners for a living. Some are vapourisers, most are pressure jets. The pressure jets can be run with thicker oils, but the vapourisers really need a consistent, low viscosity oil. They also need a stable flue draught to avoid poor combustion.
Yes it's possible to get them to work, but for WVO a pressure jet really is needed, otherwise you could be a target for the local authorities, if you upset your neighbours with the smoke and smells.
Generally, wood is so much easier to deal with.

Sometime I think I must be nuts for some of the Idea's I come up with. I've been looking into Wood Gas Generators, the main purpose of a wood gas generator also called BioMass Gasifiers, is to operate gasoline or diesel engines. A small version can be made using only a 5 gal metal bucket, you can look at one at www.youtube.com/watch?v=XGhYcnq7HfQ&feature=fvsrSo I'm thinking why not inject that wood gas into a rocket stove and gain heat from both the Biomass Gasifier and the Rocket Stove, or the Biomass Gasifier could be operated outside the house and only the wood gas would be injected into the rocket stove. The gas could be introduced into the rocket stove after the rocket stove is warmed up with wood, once that is done the Biomass Gases could be introduced into the burn chamber of the rocket stove and gain heat from both if both are in the house.

My understanding is that if the rocket stove is run correctly, it does the gasifying and combustion in one integrated process, so no need for a gasifier. The gas could be used in a gas cooker to have western style controlled cooking, but that would leave a lot of heat being wasted in the gasifier. You could have a suitable stove such a a sawdust stove www.ashden.org/images/hi_res/ksg08b.jpg or a rice hull stove bioenergylists.org/en/content/parts-continuous-flo which are integrated gasifiers, and do very well at using waste products for fuel, and in an efficient way.

Hello everyone,
I am from the Netherlands and have build an 8 inch RMH system more or less according to the book (mass bench approx. 50% finished). I have posted my questions and build progress on a Dutch forum and have received good help there, not in the least from Peterberg. I have tried a simple test myself on burning vegetable oil. I read the Mother Earth article and this is what I did: I started the system on wood and when I had a nice bed of redhot coals in the feed tube I put a tin can on top of the hot coals. The can is about 2/3 the width of the feed tube and the top is just under the burn tunnel ceiling. From a distance of about 2 feet I started dripping sunflower oil into the tin. This evaporated quickly and gave a very bright burning flame mass going into the burn tunnel. I didn't look what was coming out the chimney, but I suspect the amount of fuel being burned was more then the rocket could burn efficiently. This can be controlled quite easily by regulating the flow of oil. The oil was at room temperature, but should be preheated for best results. After initial testing I added a bunch of nails to the tin, this helped the oil to evaporate more quickly. The nails get red-hot. I am not sure whether this setup would continue to run without the coals.

it will not work well, coals to burn quickly and the oil starts to smoke, have already tested it at home, The furnace blower or pressure needed. Tested it at home, but it does not sensu.Rocket stowe is a typical wood stove.
do spalania oleju sa inne palniki i piece the combustion of oil are different burners and furnaces
