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.
Peter, or Canyon, have you measured the temperature in the embers? That's my forge obsession comming back
Tomorrow, I'll change the stove again and will insert the temperature sensor before lighting it. The Testo is operational again, more results and maybe conclusions in the coming days.
+52° 1' 47.40", +4° 22' 57.80"
vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?

yaya: you dont need the blowair for that temp..

flybywire: Glass window from an old washing machine is designed to take high temps. Cheap solution to your need.

deadstarsstillburn: Hi there. I was directed this way by folks on the Permies.com website and am hoping I can get some information on how a total newbie can get started designing, siting, building, and not-dying-in-a-horrible-house-fire with a new RMH in a 160-year old home
Oct 21, 2020 6:52:10 GMT -8
deadstarsstillburn: The people over there recommended either a 6" batchbox or an 8" J-tube. I don't know what those are but am going to try to figure that out. What I need is a blueprint that I can scale to fit the need for my house. I have something likne 5000 square feet
Oct 21, 2020 6:53:00 GMT -8
deadstarsstillburn: but I do not need to heat all of it by any means. probably only need to heat half of that, maybe less.
Oct 21, 2020 6:53:15 GMT -8
deadstarsstillburn: moreover, the house has 3 storeys (large attic) so I assume if I get very efficient heating on the ground floor, that will go a long way toward heating the upstairs as well, no?
