IMG 1287. Tweaking the vortex stove

I have found the stove has been running a bit to hot for comfort so let’s see if we can throttle it down a bit….

I really enjoyed this longer look at your burner. It really is most impressive. It's amazing also that the strong winds are not interfering with the burn. My own experience has been that strong winds can create sufficient back pressure to affect the burn but yours remains stable and clean. Thanks for sharing 👍👍💯

Yes I was surprised too, however if you look really closely there is one occasion where some smoke escapes the fire box from a severe blowback! I also forget to mention the air hole exit size has been enlarged from 25 - 28mm but I may try 30mm next time. The draw is very powerful but the chimney is only 9’ tall and surrounded by trees so not ideal.

have you thought about getting one of those spinny things, or making your own? i've seen some designs of automatic windcatchers on here@@foxfish7115 Edit: something like this: kzbin.info/www/bejne/fWbQiHlqn5J-otU and: kzbin.info/www/bejne/mpSaeWytj6uAh9U kzbin.info/www/bejne/r4rZo4Sapr6amac

So, I've been following your videos for some time now and I truly admire your ingenuity, craftsmanship, and willingness to share. Watching this video made me question what the little hole was for in the bottom of your riser. I think I've seen you use that to place a cylinder, supposedly to help organize the vortex. But looking at the hole like that made me wonder what would happen if we used that spot to inject our preheated secondary air?

Thanks for watching, the air travels under the firebox and comes out of the hole in the center on the vortex chamber, you can see me pull out the plug at 4.12 in the video. The vermiculite is quite insulating but the under side of the floor area will still reach 250c so the air will be pretty hot by the time it reaches the hole. It might work even better if the floor was cast in refractory cement but hot air expands more and more the hotter it gets so the supply would slow down If it gets to hot. I have not tested this aspect very much, just made an educated guess about the size of the tunnel that travel undef the box.
