That's à P channel.

Well, my take on this.

We already have plenty of tools, J tubes, Batch, DSR Radiators, accumulators cooking plates, ovens etc. To fit most of our needs.

I can see the appeal to à stove which wouldn't need to be stoked every now and then, and burn for a fair length of time, without needing attention.

But, this comes at a cost. The fact that the chances of it burning badly are far greater.

Plus, since the mass is recovering the heat which would be otherwise  wasted, and redistributes it inside afterwards.  The need for long burns is mitigated. Well, in the alps, at 1500m altitude, in a ski resort. I do mostly three loads a day, when it's cold. Two in October/November, and 2 End of march/ April. May be 3  in the evening, and one relit, in the morning on the embers, when it reaches around -20c° But i spend may be 1/2 an hour, between startup, and the three loads. May be if i pass nearby, i would stoke it once or twice an evening. The stove is downstairs, in the workshop. So, i don't see that much of a need for long burns. I startup around 6pm, and it burns full blast till 10ish. Usually, by midnight i can close the chimney flap (20% of airflow remaining)

Well, i would be afraid of the wood deprivation. I mean, if there is only one log in there, and it doesn't burn fast enough. And there is not enough embers underneath. This cools the fire. And kils efficiency, up to the point the fire stalls. Or stops.

You know, along the top load vertical batch. There is another solution, top load horizontal batch. Exactly a per the book batch. With a metal cookplate  hinged on top. With a handle. You would load from the top. Instead of the front, but it is exactly the same. I think with a strong draft, may be the firebox could be extended upwards a smidge, over Peter's designs.

But the problem, is the full burn. In a batch, it starts somewhat tame, and then the full dragon breath comes in, where all the logs are on fire. And if you have too many logs, stacked in the top extension,  this would overload.

What are you trying to achieve, being interested by the magazine rocket?

The air going through the wood is one of the principles of good rocketry.

Basically, you're reducing the free air circulation area, with burning wood, so the air velocity increases, augmenting turbulence and thus mixing. The port in a batch is there to increase the turbulence, but wood, either in batch or J tube is responsible for  the turbulence too. Hot burning gases take some room to, so the air intake gets faster. Well you see what i mean?  

HTH.

Well, not having seen one in real life, i can't  really comment.

I argued with F styles, that this wasn't a "rocket stove" I'm not that sure anymore. It can work with wrist size fuel, even smaller, i think.  There might be an use for a stove like this. But this is not documented, over the course of several years, with measurements, follow ups on the mods etc. I would have loved to see "testo" graphs of this. And less bragging. I think there is a real risk of flashback. It could be interesting if someone with a few builds behind him, would make on of those, to see if it's worth pursuing. To get a more "sensible" evaluation of the thing.

As far as I know they are  of the size of those from asbestos and thus being equally harmful.

If you're using superwool it has a very low bio persistence, as they say.  

Fox, put a cooking plate on that firebox!

Eliot, keep the front and the door. That could be useful for a batch. And if there is a smooth cast iron plate, keep that too, for cooking.

Gerry Parent wrote:Hey Satamax,   When the wood is loaded vertically into the firebox, what is to keep it from leaning up against the glass or more importantly, up against the port and block the air flow?

Also, I guess the floor is flat with no angled bricks?

Fox,   Its been a while since I last saw your cook stove. Could you post another picture of it when you send your sketches so we can compare them?
As for the heat from the barrel, couldn't you just put a heat shield of some sort around it or cover it with brick or cob?

Hi Gerry.


Well, leaning against the glass, ney bother, it doesn't matter much. As only a small portion will touch at any given time. But a grid of some kind could be inserted there too.

Angled bricks could be used at the bottom, but it would be a pain for loading wood, which would need to be far shorter than firebox length. Mind you, it could prove interesting to light the stove.

The port doesn't go all the way down, so it doesn't get blocked by embers. On top, a wide  "P channel" out of thick steel could be implemented. Onto which the lid could hinge.

But i need proper materials, not salvaged heat riser and ultra thick bread oven bricks.

I have a few vids of the vertical batch.



Mind you, it's not tested completely.

Aaron, try to check what is the legislation about kachelofens, where you are. A "batch box" is a kachelofen, more or less. I can see houses facing yours. And i'm dubious you would get away without trouble. Exhaust against a wall can be done, if you are absolutely sure that there won't be  a wind gust which will put your fire out, and smoke the whole house. Remember, this could kill.

What i see, is the right hand corner of the room doesn't seem busy. You could fit a bell there. And a U turn bench, in place of the radiator. But, since the wall is not insulated, this is not the best place. Better heat inside walls. Which retain heat inside. And spread the heat to other rooms.

I am partial to batch boxes. J tubes are too finicky for my liking.

HTH.
