I've been wanting to build a waste oil heater for many years. Our shop is presently unheated and with our plentiful supply of waste glycerol and a regular supply of waste vegetable oil, the research demonstrates that a babbit ball "nozzle" oil fired furnace would be the best way to get our shop hot. The machinist who drilled the teensy hole in our babbit nozzle has a wood fired rocket mass heater assembled and working wonderfully in his domiscile. The more I look at the design of the RMH, I keep thinking that it has to be the most effective way to distribute produced heat from any type of furnace, even a propane flame. So my grandiose idea is how to build a rmh that takes in the flame from a babbington burner. These burners can produce 2-3000 degree flames that are 5 foot in length depending on your flame tube and by themselves can entrain a very strong current of air. I have a pair of 5 or 6 foot 3" steel pipes that could be used as a riser tube for the flame and wonder why if well insulated with a perlite filled tube this wouldn't work wonderfully for the vertical portions of a RMH.

I understand that a waste oil heater isn't the highest of permaculture designs, but this forum appears to be the best place to gather and share information on how to build one of these ingenious creations. Heck, they even have the compressed "air" portions of the babbington burner supplied by steam produced by the burner.
We're still assembling the materials for the babbington heater and with only a little more work, our pile of supplies can include what is needed for a RMH, so I'm thinking, why not go for it, have it all.

I've considered building a babbington burner my self. At those temps. plain steel will just burn up pretty fast. I would use cast refractory or fire brick for the burn tube.

Should work plenty fine, you will have to alter the stove to allow for the air intake that would be required and use masonry in the burn tunnel and heat rise. I dont know what the effect of something already putting out 1000 deg will be on the system it hit 3000 in the heat riser as is from wood. you might do something i have not been able to do yet; melt a barrel. if nothing else it should be cool.

i built a Babbington Ball waste oil fired boiler to heat my house last winter.....if you are going to build a babbington ball version of a rocket stove be aware that a vertical riser with no gas flow restriction will probably have a issue with the flame 'running away' down the tube and up the riser before flaming out= smoke out city lol....the 'draw' that a babbington generates has to be seen to be believed

While i am not the guy folks usually think of for liquid fuels I have a little bit of experience About enough to get my eyebrows singed off. I would suspect that the device would need to be rather small in a RMH setup and that i would have to build in forced air to make up the volume of O2 the oil would need to burn clean. same would go for an old style oil pot burn with pumice for a wick. it would have to be very low fuel volume and very high air volume to work correctly. one of these days i will tinker a bit and see what comes up.
 
I agree. Here's the link: http://richsoil.com/email
