Firstly (of course) kudos, well done and thank you very much!
An initial first batch (get it? haha) of typos, and in a couple of instances 'awkward' english.
(introduction) 'sometimes Rocket Batch Box of RBB.' Presumably 'of' should be 'or'
(workings) What is actually a wood fire? Not a biggie, but might read better if 'what actually is a wood fire?'
During the combustion of wood de organic typo, should read 'the'
(turbulence in batch box) The composition of riser and combustion chamber is called the "core". Perhaps a better word might be 'combination' or somesuch.
(heat) Another evironmental factor is just as important: high temperature. This isn't to be taken lightly, during development temperatures as high as 1200 degrees Celsius ( 2190 Fahrenheit) has been measured in the riser. typo and 'has been measured' should read 'have been measured'
(limitations) A relatively small change could be enough to disrupt the correct function of the heater. Should read 'correct functioning'
(testo) This device measures of every "run" the temperature of the exhaust gases, the oxygen level (O2) and the content of carbon monoxide (CO). Was not quite sure here, then realised (?) you might have meant 'in'?
(wood fire, para 2) It becomes necessarily to build something around in order to shield it from the surroundings should read necessary
para 3 can be smelled over a large distance as excitatory stench. Not quite sure how to rephrase this one! Maybe just keep it as 'can be smelled over a wide area in the outside environment' or similar
para 4 Literally everything of the wood composition can be converted to heat, so is smoke. A tad awkward here. How about something like 'Quite literally, the entire content of wood can be converted into heat, and that includes smoke', or '....into heat, and as such smoke is an indicator of incomplete conversion of wood into heat'... Depends on what you meant to say.
para 4 A plume of smoke rises, the signal of wasted fuel. just 'sign'
(mixing and turbulence) para 3 The common systeem which is used to induce enough turbulence is injecting fresh air at a number of locations at the same time typo
For most of the metal stoves this isn't a pity, tad awkward, maybe problem instead of pity?
(turbulence in the batch box) The secundary inlet is typo (and occurs later)
air is sucked in automagically unless a deliberate play on words should read automatically
para2 This can be considerably, caused by the molecules loosing speed abruptly..... considerable and losing
para 3 The net effect is violent turbulency and prolonged turbulence
(lots of heat) ' In turn, this has a positive effect on efficiency, more gases are burned and complete combustion will be achieved in a shorter time frame during the burn'. Perhaps you meant to say (?) 'complete combustion will start much earlier in the burn cycle' or similar?
(restrictions) clean combustion is only achieved at a sufficient high gas velocity. sufficiently
(results) Both the level of oxygen as the temperature of the exhaust gases (the blue line) have its influence on the efficiency (the red line). (i)And? (ii) their or an?
para 2 the effieciency will be higher typo
(explanation between graphs) 'The "very good" part of the purple line is smaller here coupled to a steep rising end. Plus, the oxygen level doesn't drop that far but still quite nice. Of course, every situation has come by, very bad runs also. Caused by trial and error so things will often are getting from bad to worse'. A tad awkward again, happy to give it a go re-writing for you.
Most of these are simple typos, and a little grammar. I hope this was the sort of help you were looking for, it is in no way a criticism as such. Heck, ask me how good I am in another language.

Thanks Terry,
I'll implement the changes today. About the explanation between graphs: I was very tired, late night and so on. The structure of the paragraph is definitely Dutch, not English of whatever origin. Please be so kind to correct this paragraph, I am grateful for your help.

OK, changes are done. Had trouble spotting the typo in secundary. In Dutch it's secundaire.  In English the root is second instead of secundo, obviously. There's a lot more coming, yesterday I started the chapter "How to build and what to use". You are doing good work, thanks again. |

glad to be of help Peter, I think we all would like to give back to you in any way we can! After all, my kitchen (as but one single example) is quite toasty this morning due in no small part to your efforts and indeed this current effort of yours under discussion here.
I see you have been a busy boy overnight. Anyways, just a quick re-write of that particular paragraph.
'The reason this graph, whilst excellent compared to 'steel box stoves', is not as good as the previous can be seen by comparing the pink and green lines of the graphs. The low plateau of the CO line (pink) is not as long, started later and ended earlier. The green line (excess oxygen) did not go as low yet is, in itself, a good result. During the development phase all results have occurred, good and bad. Many times a change led to worse results. That education has allowed me to present these plans as a workable and easily understood final result.'
Taking a few liberties, I fleshed it out a bit. As such it is most definitely 'not you' in style or content, but does (I think) explain a bit more to the reader that is coming across it with no knowledge. You,I am afraid, are a walking encyclopedia in this area! You have forgotten more than most of us know. It is possible then that some things get left out because it might not occur to you that others don't know. Anyway, if I am being presumptuous let me know.
'Comparing the graphs we can learn a few things (like why the testo is absolutely essential in knowing exactly what happens during a burn) and see how this burn is more representative than the 'cherry picked' stellar example just above. As you can see the extremely low CO levels (pink line) which indicate complete combustion does not occur quite so soon as before, nor does it last as long. Also observe that the Oxygen level (green line) does not go as low, but is still at a very nice level. The oxygen measurement is known as 'excess O2'. Strangely enough having too much oxygen than required for complete combustion not only does not contribute TO the combustion, by definition, but also cools the fire. During development of what is presented in these pages naturally all permutations have occurred, including very bad runs during the trial and error tests. It is only thru the testo that we have arrived at a 'build by numbers' system presented here.'
I will look at the next page tomorrow. That way I will know if I have overstepped the mark and should just concentrate on typos and the like.

quick perusal of the latest chapter, limited to typos and obvious incorrect grammar.
(materials) combined with each other or secundary materials secondary
(diy build masonry) and materials which are relatively easy to come by in most places is a good result entirely possible. Omit the 'is'
(materials, para 3) especially the somewhat coarse kind mix with a little bit of clay and some atwer to prevent sagging. Typo
(metal, last para) I come back to that when it's appropiate. 'I'll' and appropriate (typo)
(scalability, 1st para) The bulk of development has been done is 2012. Either 'was done in' or simply replace 'is' with 'in'
smaller ar larger versions typo, 'or'
Measurements of the 150 mm system were avaiable typo, available
Uptill now (2016) typo, up till or better, up until
(diy build masonry para 3) 700 degrees Celsius (1470 Fahrenheit) quite easy. easily
(last para) Take care there's no fuel, whatever small piece, is sticking in the port itself. Probably best if '....,however small the piece, sticking in...' or 'however small, sticking in....'

Did the corrections, including the paragraph between graphics. You are right, it is definitely not my style. Probably only the Dutch version is entirely my style anyway. It's obvious I am still learning, also staying up late at night isn't very productive. In the build chapter a big chunck of text is waiting to be done. After that the even larger core designs chapter will be next. When all that is done, the applications chapter need to be set up from scratch. I won't dare to think about translation of that one for now...
At the sideline a guy (not Lasse Holmes) claiming the batch rocket is developed from his experimental heater. The third in 4 years, hope this doesn't hold a promise for the future. It'll keep me busy, that's for sure.
One guy I used to work with said long ago: "Don't learn a monkey how to climb, or you'll get the coconuts on your head." Lot of wisdom in those words.

Hi Peter. First of all, thanks for taking the time to setup the site. Yep, credit for the very first "online" experiment, could be given to Lasse and Kirk. donkey32.proboards.com/thread/511/adventures-horizontal-feedI know, you have troden that path before. But about the other guy. Ask him to prove that you were aware of his design before the batch horizontal feed thread started. And ask him for a proof of recorded prior art by himself, like a Soleau enveloppe en.wikipedia.org/wiki/Soleau_envelopeWhich would proove that he can claim a patent. Wich he would never get. As most of the techniques are into the "public domain" class. I wish very good luck to anybody wanting to patent this. As wood fire has been part of our evolution  |

Hi peter,
A little question : in the chapter "How to build and what to use", section "Dimensions and scalability", you didn't mention the possibility of having a heat riser half as long. I haven't tried it yet, but somewhere in the forum shilo showed that it could work very well. It is a nice news for batchbox cookstoves since it allows cooking at a reasonable height, so maybe it could be worth to add it ?

clean up of a few extras
how to build what to use page
(materials) para 2 temperature the clay should be reasonable strong by then reasonably
Very little mass to heat up and very insulating but vulnerability to abrasion as disadvantage at least 'as a disadvantage', prob better if 'but have a vulnerability to abrasion as a disadvantage'
para 3 especially the somewhat coarse kind mix with a little bit of clay and some water to prevent sagging mixed
(metal) para 1 Concerning metal in constructive parts: this will lead inevitable to disappointment inevitably
para 2 is compromised which will result in incomplete cumbustion once again. combustion
However, for some parts using of steel could be feasible, I'll come back to that when it's appropriate. A bit clunky, easy fix is 'the use of steel'
(building a core) 1st para The top plate can't be made out of these brick because those are too short for this purpose at least 'bricks' and 'they', possibly better (?) if 'these same bricks' and 'they'
para 4 but pertinently not in a bit clunky, something like 'definitely'
(casting a core) para 1 the castable need to be mixed with as little water as possible and a vibrating table is best to drive the air out. needs (just as an aside, sure it is best to use a vibrating table, but are you doomed to failure if you don't have one? In other words, if you do not have a vibrating table, forget it?)
para 2 The recesses could be implemented using extruded polystyreen foam polystyrene. We know exactly what you mean, however recesses is not quite the right word. Dunno, is cavities/hollows/voids a better word? I guess there is no point putting it back on to you, so how about 'The internal shapes can be formed by using extruded polystyrene foam or any suitable material that can be shaped by you, MDF, builders bog, wood.' Again, that is 'not you' so modify accordingly. If something like that was adopted, then 'Working this foam can be done with a good table saw machine' would become 'working these materials can be done' etc.
[arrggh, should have read a bit further, you kinda covered all that. Still, take what you want from above]
2nd para after photo beewax is good. beeswax
Don't forget to wipe excess oil with a rag wipe off
para 4 excenter on the axle fixed off centre (or center, american spelling) [and as before, I should have read ahead, you are covering my question above about using a vibrating table]
But... it can be done much, much simpler. A bit clunky, 'more simply' perhaps. or, 'much more simply'
same para, equipped with a simple excenter would work as well. again, off centre or center
para 6 Most of the refractory castables can be released in 8 hours at room temperature after
para 7 The solution is to be find in dividing the whole thing in such a way that the hotter and cooler parts are separated found
sorry about not reading ahead at times.

Maybe the word excenter isn't clear, I see it isn't common English. Not the induction motor itself is off center, but a strip of steel fixed to the axle with a bolt. The strip is sticking out on one side because the hole isn't in the middle. I used eccentric strip now. When this isn't clear either I have to take a picture of my table and use that to illustrate.
This strip act as a crank, when the motor axle is turning it causes the whole table top to dance up and down a few millimeters.

You are right, it can be done. I don't think it is half as long but it is shorter, that's for sure. Only effective in combination with some other measures around it. The bare core on its own is not as good, it need to be in a specific surrounding. The whole thing is an implementation of a rocket cook stove and as such it belongs in the "Applications" chapter which isn't written in any language yet. |

About making a dead simple vibrating table. I have posted it before. I will dig it later tonight. May be linking it on your site or even embedding it. If the guy is OK! |

Max,
There's a link to a video in my text: the one with the car tyre. I tried a couple of times to embed a video but this wouldn't work, don't know why.

In English the root is second instead of secundo, obviously.
