thanks morticcio, it is very interesting ... I can not wait to try it, though for now I'm still developing the firebox

Broken riser works well enough for me, my test system was running with sub 100ppm CO and mid 80% eff. You can certainly do better, but I find that performance acceptable. I think your design is a good one, I'd put the chimney exit at the bottom of course, and really just about any side of the bell seems like it would be fine. I think it's a nice looking system, makes me want to build one. People keep talking about having trouble posting documents to the forum. I suspect it's just as it says, we've used up all the on site storage. Host the files somewhere else and link to them here instead. Thanks for reply Matt. You are using a j-tube simple or optimized with P-channel and trip-wire? I use them. How could you improve the performance of the broken riser? My main problem with the j-tube is that it burns too quickly and I fill the combustion chamber embers. Unfortunately, not having instruments can not assess improvements in development, but tomorrow I'll try a broken riser with the measures that you have posted in the post dedicated to the topic. In the drawing I posted, the chimney is on the bottom as you advice, just that I have some doubts, but not being able to attach the file skp not think I can explain. I know of a site that allows you to upload files that are not images. sorry maybe I'm wrong section to post this morning, I had a lot of sleep, if you believe necessary to please the moderators to move the thread

Well close your browser and restart it again. I think there's a bug with the forum software. If closing, clear your cache, close and restart. Try again. After all that. You will ask someone more qualified than me. thanks satamax try, though on other occasions there have never succeeded.

Hi I created another design for a kitchen stove, if broken riser work properly you could have a good heating oven, heating plate cooking and heating of the heat exchanger. Is enough space inside, is not as contorted as the other drawing the gas should not be too slow. I'm just undecided where to place the chimney, you have some solution? satamax I started using the object-oriented design. Why I can not attach files skp? tells me that the forum has reached its limit, how can I do? thanks

Hi I suggested a design for a rocket stove in horizontal loading, the dimensions are random. what do you think?

Thanks to all I would like to know also if the presence of the bell can improve or worsen the quality of combustion ? In a J tube combustion chamber must be black ?

Hi I do not own measurement instruments for gases, therefore, I would like to know if there is an empirical way to judge whether the combustion quality. Amount of residual ash, heat generated ... In short, there is a way to evaluate? thanks

I wonder how these temps would compare - all other things being equal - to vortex's (semi?) widening sloping riser? Might the gasses be happier if they have more freedom to expand sooner across the sloped surface? A J-feed or batch box with 12" of vertical riser then widening to 12" across by 6" deep at 45 degrees slope? Sorry I do not understand what you mean..My English is very bad .

No.. I think you've done it the way (or close enough) that Matt has described it. It's just weird for ME, after years of looking at straight, vertical heat risers.. I'm intrigued but sceptical. Yes, I do not have much experience , but the inclined position of the riser does not seem natural , I noticed that the back of the riser tilted warms more than the rest ( obviously. .. ) the heat tends to go up ... a trip wire to drive the heat would be ideal . The stove part well in ignition , but then seems to slow down , the fire becomes less vigorous . I measured T output from the riser angle of about 250 ° C, compared , at 400 ° C with the vertical riser of the same wood seasoning. I do not know if the test is reliable , would need a serious experimentation ..

Max, I compared the same combustion units with broken riser and vertical riser in the same conditions, I noticed that the broken riser smoke more. Then isolating obviously improve, but the vertical riser will improve in the same way. Would serve a thorough study to properly drive the gas within the combustion chambers.

Hi I did some testing without instrumentation because do not possess: My broken riser (maybe wrong ..) and this:
batch box kitchen question
are not very experienced, but I noticed some things in my system Boken Riser. The shorter the combustion chamber more smoke (seems obvious). The heat riser seems to have the sole function of directing the heat but in my case it makes a lot more smoke and does not stop. The draw is great with short combustion chamber. I thought that having more friction inside the inclined riser, as Peter says, it would have been favorable to the "three T's" My flame but never reached that point.
As I mentioned I'm no expert and definitely do not allow myself to judge this work, it's what I've found in my system.
I hope you understand my bad English
