Hi all I am new here and this is a great resource. I don't know if this has been covered somewhere already. I have searched the threads and sites like permies and have only found passing remarks on using oil like WVO or used motor oil in a rocket. I am currenty in the process of buying land to start a sustainable homestead/farm and would like to use a rocket to produce large amounts of hot water. I will be using several sources such a Solar but I need fuel back-ups. Can a rocket be used in such a way like dripping oil into a container with a pile of crushed fire bricks or so on. I know about the mother earth style burners but a rocket seems way more efficient. I apologize if I missed the thread. I will be experimenting on my own but learning from others first is a great start. Thanks Shaun,
P.S. Thanks to all of you that have taught me so much so far especially Peter and Donkey

Welcome to the boards, mate. Some folks have fooled around with the idea but I'm not sure that a really good solution has popped out of it yet. WVO and wood need different conditions to burn happily and building a multi-fuel firebox is tricky. I'd LOVE to see it done well though, so PLEASE! Figure it out (you got help and encouragement here if you need it) and post your results!

Thanks for the encouragement, Well It seems this is definitively something to develop. I have a bunch of different designs in mind to try. I will be coupling this with testing propane tanks for a heat exchange barrel (which I want to call a heat exchange bell from this point on unless somebody objects). As I mentioned in that thread I have to get a shop up and running first and get my wife's green houses built first. I hope to be up and running in about 6 months. Once I start I am going to build a test heat exchange bell that has an explosion safety devise and gas sniffer built into it before I post any videos, pictures or results. I am afraid that there may be some dangers of accumulating gasses in the exchange bell chamber during the start up and shut down phases. I don't want someone copying one of my test designs and blowing themselves up. This will all take me at least a few months, after I am up and running, to get set up. So don't think I have given up. However, any talk and Ideas that can help set a plan or design in motion will be greatly appreciated. Karl, that is a good start. I will study the design closer shortly. Some of the aspects I am going to be working on is that the system is not to fussy like maybe a bottom feed gravity system into a small burner container. I believe what donkey has said in a few posts is true that the more complicated some thing is the less likely it is that others will try to build the technology themselves. I will also work on a more complicated self starting thermostatically controlled system once I can tell that a viable burner system can be developed. Thanks all,

Umm. I've been thinking about re-naming the barrel too, as it ain't always a barrel. The word "bell" though kind of already has a definition that the rocket stove barrel doesn't quite fit. I do believe that to be considered a "bell", both the heat intake and outflow need to be at the bottom of the chamber.
Peterberg might want to weigh in here...

I thought about that right after I posted it. Maybe just heat ex-changer would work.

Maybe, though the term is rather generic.. What's needed is a more descriptive term, something that describes the placement and use (or something) and sets it off from other kinds of heat exchanger. ?? I dunno...

W piecu-rocket sove nie spalisz dobrze oleju,wcale go nie spalisz tylko uzyskasz du¿o dymu i smrodu,,feeeeee to piece typowo na drewno,przerabia³em ju¿ ten temat, Za ma³e jest doprowadzenie tlenu do spalania oleju w rocket stove Je¿li szukasz najprostszego palnika typowo na olej,napisz podeœ³ê ci to co zrobi³em i olej spala siê bez dymu,ale nie popieram tego !!! TOXIC
W warunkach domowych wogóle nie powino siê spalac olejów przepracowanych, zawieraj¹ za du¿o trucizny w spalinach, których nie jesteœmy w stanie stwierdziæ Ale sporadycznie mo¿na spróbowaæ,
Spalanie oleju wymaga wielokrotnie wiêcej powietrza i najlepiej nadmuchowego na palenisko to najtañsze paliwo,,i stosunkowo wydajne,nie mnie jednak uwa¿am,¿e nie nale¿y przesadzaæ z zastosowaniem do w warunkach domowych
In an oven-rocket sove not burn oil well, it does not burn just get a lot of smoke and stench, feeeeee is a typical piece of wood, I transformed this subject already, Too small a supply of oxygen to the combustion of oil in the rocket stove , If you are looking for the simplest typical oil burner, write this photo I will send what I did and the oil burns without smoke, but I do not support it! TOXIC,poison
In the home at all this should not preclude the burn oils, contain too much poison in the exhaust, which we are not able to tell. But occasionally you can try,
Combustion of oil requires many times more air and blowing the furnace is best
to the cheapest fuel, and relatively efficient, but I do not think that you should not overdo the use for the home

Pluton, I agree that its not a good idea to burn a used motor oil burner in the home although lots of people do it. However, the the temperatures in a properly built rocket can reach at least 1600 degrees. well within the range to have complete combustion. I would love to see what configurations you used and how you set up your delivery system. Now I am even more intrigued and impatient. I think I will take the kiln bricks I have and make just a burn chamber and heat riser and try some different burner delivery systems. I will try to borrow my friends testo and do some emission readings.

Ja zrobi³em najprostszy palnik tego typu,kilka metalowych profili,powierciæ otwory, pospawaæ i dzia³a bardzo dobrze i jest bardzo wydajny, spalanie oko³o 1,5- 2,0 litra/h. Wentylator z auta z regulacj¹ obrotów spisuje siê bardzo dobrze. œrednica palnika,,oko³o 12cm(5 cali) Lepsze wyniki i wy¿sze temp.mo¿na otrzymaæ w komorze ceramicznej. Moim zdaniem do pieca rocket stove musia³byœ pod³aczyæ dmuchawê-wentylator , ale trzeba zmieniæ komorê spalania i wtedy by³oby OK U¿ywaæ taki palnik w otwartej przestrzeni,,nie w domu link www.elektroda.pl/rtvforum/topic1542907.htmldu¿o wiadomoœci-palnik,olej,itp I did the simplest burner of this type, a few metal profiles, powierciæ holes pospawaæ and works very well and is very efficient, burning about 1.5 - 2.0 liters / h. Fan with variable speed of the car is doing very well. diameter of the burner, about 12cm (5 inches) Better results and higher temp.mo¿na receive ceramic chamber. In my view, the rocket stove furnace would have to plug in the blower-fan, but you need to change the combustion chamber and then it would be OK Use the torch in open space, not in the house link www.elektroda.pl/rtvforum/topic1542907.html a lot of e-burner, oil, etc.

W temacie jest mowa o spalaniu oleju przepracowanego w piecu ROCKET STOVE a nie o innych wynalazkach. Znam ca³a masê takich urz¹dzeñ do spalania oleju, w których olej spala siê doskonale,bez dymu,,,,czyli niby wszystko w porz¹dku bo nic nie widaæ z komina,a to czego nie widaæ jest dozwolone.tak?
To jest chyba temat na inne forum bo siê Donkey zdenerwuje,¿e zaœmiecamy mu temat.
The topic is talking about burning used oil in an oven Rocket Stove and not on other inventions. I know the whole mass of such devices for the combustion of oil, which burns oil well, without smoke,,,, that is, like everything's okay because I do not see anything out of the chimney, and you do not see what is allowed so-good?
This is probably the topic for other forums because the Donkey upset that cluttered his subject.

This is probably the topic for other forums because the Donkey upset that cluttered his subject. Go ahead.. This thread is about burning oil. If we put our heads together, with energyseeker as a willing test subject, something interesting (perhaps even useful) might come out of it. Is it possible to use a rocket stove heat riser to create enough passive draft for an oil burner? Śmiało .. Ten wątek jest o spalanie oleju. Jeśli zbierzemy nasze głowy razem z energyseeker jak chce przedmiotem badań, coś ciekawego (może nawet przydatne), może z niego wyjść. Czy można użyć rakiety pionu ciepła piec do stworzenia dość bierny projekt palnika olejowego?

Spike's oil heater shows that natural draft is enough for a pot type burner. To implement it in an elbow however may not be an ideal solution. The problem with a pot type burner is to get the pot hot enough to vaporize the oil. In Spike's oil heater the air is sucked into the burner when the oil is already vaporized and thus does not cool the pot down to much.

The elbow is unnecessary, mostly a convenience. How would you modify to support oil burning? Could the same "back down to the mass" arrangement be accomplished with oil? Would it be worth the effort? What's to be learned by it all even if it doesn't work?
