Dear Martyn, I am surprised by the material you use: Vermiculite Is that just for experimenting? Or is it the material you would use for a daily burning stove? The parts that are in danger of abrasion, are protected by Glass?! Thank you for your great experimenting and collecting information elsewhere! All the best Kyrill

Hi Kyrill, good question.
If I was going to build a vortex stove to go in my house I think I would use refractory cement for the fire box and vermiculite for the upper workings.
However in my case I have found the vermiculite board to be really good and long lasting, if you can design you stove to be accessible enough to replace the board then I think it would work as a fire box as well.
My J tube rocket stove has used the same vermiculite fore box for two years and still looks great!

I have responded to it in Yt comments Very clever way of keeping resistance without increasing the throat size much We may set this date as a festive one. Thank you sooooo much.... Cant waitt to see whether the slopy glas will allow for a wider throat. My lord.! I 'd play with the parameters with such a joy... It is below zero C here and my allotment garden building would accumulate that amount of heat with the highest pleasure. Disappearance of the vortex while providing the bottom air may be caused by the CO being ignited right above the coals, instead of afterburner,thus causing the amount of volatiles to be insufficient to create vortex. |

Excellent work as usual martyn. To get that bottom air to work correctly I'd make it so that is the only way it can go, as it will always take the path of least resistance. Maybe you could make a piece to cover the front of the V-floor so it directs the air from under the sides of the V to just the middle some how. |

Another question for the Vortex developers- is there any scope to increase the depth of the firebox by a small percentage? I'm going round in circles trying to decide whether to build something like Martyn's vortex J tube, or a 4" shorty, or a 4" vortex, but my firewood is cut to 1' lengths....

17" firebox x 0.666 (4" scale) is 11.32", so it's not that far off anyway, cant see any major issues there if you maintain about the same volume firebox.

Thank you for the reply, yes it's only a small percentage adjustment and seems do-able!
