Rocket Stoves

Furnaces misaligned, asymmetric – “rocket”

The most important information about this topic can be found in the tab: Bibliography or in the sources collected by us:

  • The theory of item. 53, 54, 55, 56, 57, 58;
  • Movies No.: 54, 55, 56 – + … : 13, 31
  • Sketches (dot. for such furnaces..!) – Dakota fire hole – “fox stove” No.: 1, 2, 3, 4

Aside from these, the early “Dakota Fire Holes” – some Authors reported sources indicate that this whole “Story” – began “for good” – from the early 80s.

Names are mentioned and the first to give (familiar sounding!) I quote:

Larry Winiarski, technical director at Aprovecho, develops a model of such a furnace, inspired mainly by the solutions used in the oil lamp. As you know, such a lamp, without a lamp – smoke, and when applied a vertical glass lens – smoke ceases.
This solution is used in his project Larry Winiarski and His also should be considered as the Father of rocket furnaces.

Only later comes the name of retired engineer Peter van den Berg from the Netherlands, who was the first to point out and disseminate – the technique of burning a non-punching, co-current! I recommend this very interesting literature, mentioned.

Indeed, this is a “young” story and in recent years we have seen an “avalanche” of reports ( Internet, YouTube, books) – about these furnaces and their construction.

So much of my entry to the called here.

The main and the main priority of this Forum-Blog is not to promote some specific and known type of furnace, the process of burning solid fuels itself (I prefer biomass – read: “Introduction“). My intention is to master the combustion process itself as: complete, complete – to ash (terminology:
This combustion process we want to “fit” in specific, different structures ( misaligned asymmetric “rocket”).

Searching the Internet in search of any finished furnace structure that meets this, Our overarching goal (total, complete burning) – I came across an advertisement for the furnace – “Kyrgyzstan” – on the Blog, whose founder is: Wojciech Treter Editor-in-chief (because the only one).

After that, his signature – we see there such a guiding sentence: 79 thoughts on. “Real technical progress in burning coal” – and the first comments starting the discussion:29 May 2018 at 08:53

no it still need to create a blog about constructions and the idea of stoves for pennies
surely everyone’s something they induded something interesting show

Then – immediately there is a response (to the above!):30 May 2018 8:56 AM

Such a thing arose: But a small advertisement / little interest of people and so far no one except the authors there is not given. The creator of the furnace signed as Staszek (pseud. Ranger) created something even better than a furnace from Kyrgyzstan – There the flame is blue (close to perfection) and the weight of the furnace much smaller. The cost of new materials is maybe from 200 PLN. And from scrap is for a dozen zł.

This one air makes a major difference with ranger furnaces-
there is a primary and two secondary.
At Ranger there is still a deflector, a vortex constrictor.

Unfortunately, this Editor-in-Chief (the only one) – currently ignores this, Our Blog-Forum (pretends not to see this Information at home, and – below posted, dot. Our Site!)!
Well.. it can only be concluded that this, the “overarching goal” – unfortunately – is not this, Our – in s pó l n y m .!!!

Guess Sami!

Was it – t y l k o o this, Our, indicated the process of burning with a blue flame (so advertised “Kyrgyz” – further like others – generates this bile!) or … o ” C Ó Ś ” j e s z c z e ???

Without questioning his – self-education on such a basic level (smoking shows with two “goats” + “envelope” with His Login – banners.!) – we must note that this, otherwise – a very useful and awareness-raising action (whose clou program – is only the technique of smokeless burning, co-current.!) – is already well overdue.!

This technique was popularized in the World (at the end of the last Century!) the above- Peter van den Berg – on His “rocket”.

Currently, Industry, Manufacturers – massively use this technique – with their Projects in the current constructions of new furnaces (which still burn with yellow flame.!). Exceptions are only single “cases” with furnaces of the chamber type (gasifying wood.!), but – they are far from perfect.

For the present, this 21st century (and the observed political situation, a law that completely prohibits the burning of solid fuels) – Our self-education – becomes an absolute requirement, a challenge of the present, 21st century! We must not “give up” to any malice, hateing – those who, with the deprivation of their Knowledge (and through primitive jealousy.!) – are currently unable to “take a step further” (to the most perfect combustion process, ie. with this blue flame.!).!

But in our experiments – I assure you that the design of the burning furnace w/ g indicated with the most perfect flame and these Criteria
(no fans – only the Laws of Nature!) – its shape will be “forced” by the Laws governing this World.

Sympathetically and extremely aptly, he put this “issue” in his commentary, on the aforementioned blog, a guest with a nickname – “Fireman”:Fireman June 8, 2018 at 7:50 PM (text translated from j. Ang. ) writes:

This stove (Kyrgyzstan!) – is very good, but it can be done even better. My geography teacher at school said,
that nature (the cosmos) does not recognize the principle of the right angle. The ideal stove should have a spherical (round!) – shape. Look at this stove where the Inspector gave a link: ranger / There burns a blue flame.
Soot is burned completely. Above the flame, you need a deflector to raise the temperature…- just like the Mecker-Fisher gas burner.

A’propos of the aforementioned blog wojciech Treter – I found such a comment (theorem!):Wojciech Treter on May 30, 2018 at 09:56:

This rocket is completely different. At least in canonical form. If something has a grate, it is no longer a rocket stove
in the original sense. The fact that it can be similar places, because the laws of physics rule the same, i.e. always the afterburning chamber is worth isolating, so some such ceramic channel will always go there.

In order not to enter into the polemic of dot. names (non-proprietary patent – I guess!) – I introduce on our Blog-Forum extending the nomenclature:


  • coaxial, misaligned (hearth with chimney!)
  • round, grae (hearth!)
  • “Ra”- kietowe (“Ranger”!)

I treat “Rocket” as a Challenge, because despite this “avalanche” of reports dot. like a very successful construction, somehow it is difficult for me to find on the internet or on YouTube – one, “exemplary” design. The exception (i guess..!) – is still experimenting – Mike Knop.

After many built “rockets” – finally presented: a low-temperature reference flame and only with a natural thrust in the rocket furnace:

1. Standard flame – low temperature. – natural convection for thrust – rocket furnace

Second video : Author carlschultz69 – as a reference flame with the highest combustion temperature (which can be obtained from burning wood) –
from the gasifying and burning chamber with fan support:

2. Standard flame – high flame temperature with fan – gasifying chamber

Aaa Nam is a “Rakieciaka” that could meet the mentioned. “combustion criterion” and passed the two-point “Ranger Test”, i.e.:

  1. bright pot with cold water over the flame ( + white gauze above the chimney)
  2. without yellow flame (yellow-hot soot)

Only single TLUD‘y (e.g. from our bibliography film No. 80) are close to these criteria (but these are not ” r a k and e t o w c e “!).

80. "Ranger Test" – for the presence of unburned soot in the exhaust gases



Continued resulting from the discussed issues can be found in the tabs of the Forum and Our Projects and people brave, prepared substantively and efficiently linguistically invite you to further discuss and develop this topic in the comments, below this entry.
