Yesterday wasn't my lucky day. Due to gusts of wind there happened to be a small under pressure in the workshop now and then. The stove ran well at first, but every gust slowed it down, again and again. So this testrun was, to say mildly, not the best of things.
Moreover, the O2 cell of the Testo analyzer died quietly, so no more experimenting to publicize the coming week.
hello peterberg excuse me for my English I use google ... I would like to know what model you use to make TESTO you're on the computer GRAPHIC
Hi Thierry, welcome to the board. It's not completely clear what you are asking: but I'll give it a try. The analyzer is a Testo 330-2 LL, coupled to an Acer netbook, using the software Easyheat 2.6 by Testo. The graphics are generated by the same software as well as a spreadsheet. The logging interval can be chosen, 10 seconds in my case. I'm too impatient to wait for a refresh every minute or so.
Woohoo Peterberg! Thank you so much for doing all that and sharing it! Some great runs! I wish I wasn't so very busy right now so I could join in the fun but I won't be able to for a little bit yet as this is the busy season for us natural builders in the northern hemisphere. I hardly get a chance to get on the computer. We are going to build another one of these horizontal feed batch boxes at the beginning of next month and maybe,just maybe I might to get some more data to share from this next version. I am planning on doing the peter channel built in the firebrick without steel to simplify things so stay tuned. Sorry about the o2 sensor, hope it isn't too painful to have repaired. Thanks again, Canyon

A word of warning; by implementing the p-channel in brick you won't get two advantageous aspects. Most important benefit: heating up of incoming air, and second: cooling of the first brick spanning the tunnel. But on the other hand, please do surprise me with an innovatory solution.
Up till now, I've used a part of a 4x4" square tube to cut the channel piece out. By this way, I've got the bent flanges readily done, this proved to be a very stable solution. Without the p-channel, this horizontal batch fed rocket stove isn't that good at all.
The O2 sensor being broken isn't that painful, losing several weeks of valuable time do hurt much more.

Yes, that's the p-channel. A metal plate with folded sides, the width of the tunnel and 5% of riser cross sectional area. Just above the tunnel opening, hanging down over the top end of the tunnel, same size as the gap between plate and brick.
- Currently I built a rocket that looks like your, what do you think of a cone-shaped primary arrival?
Could be done, not as rigorous as your pictures show, I would think. Let's say largest side 120% of riser c.s.a., smallest side 66%. This is a new idea, it should work like a funnel. However, it's impossible to predict what the effect of the p-channel and trip wire would be, if any.
Secondary air to the lateral as your rocket bell could work there or best result on top?
The air system of the rocket/bell could work here. I do prefer the single p-channel in this application, because it's a clean simple design and it will do the job. Simplifying and retaining the good properties at the same time is a good thing.
panos: Some fireclay products say thy exhibit resistance up to 1000 celsius.Would that be fine for a 150 mm Batch box rocket?Would it be better to search for reistance up to 1200 celsius?

idahodave: I'm getting ready to build my first RMH, and have some specific challenges. First one is that the site has a high water table, which in February got as high as 8 inches above the projected base of the heater. Any suggestions?

panos: Can someone make a sketchup file for the support base of a batch box rocket as per Peter's van De Berg following reply:

panos: those pumice cinder blocks are better suited to a base support. On top of the blocks a ring of bricks, an infill of perlite/clay and the firebox and maybe even a bell on top of that. If possible, arrange the blocks in such a way that there are channels

panos: under the whole of the heater so heat won't accumulate under there but can be vemtilated away by air currents.''

SilverFire: Yes, our designs have moved from the experiment design to production, as with the other stove models that were listed on this thread. Hopefully this will inspire others to continue to improve stove designs as we have done.

permaculturebob: citrus paint removers --"citra solve" is one and Walmart distributes another--non toxic fumes, softens tough barrel paint--sometimes it takes a couple applications and some scraping, but I prefer it over sanding and burning

martinm: Hi there ! I need chart / comparisson on : RSMH vs mass produced wood burning stoves. I need to write a proposal to local govt. to convince them on choosing Rocket stoves for supplying families in poor neighborhoods. Thank you Will look through the threads
