Thank you so much for sharing!

This is the core lovingly named Shorty?!

Pros: compact, large window, no secondary air channel necessary, very forgiving at reloading, a choice of core exhaust directions, highly resistant to fuel overload
Cons: less initial draw

Correct me if I'm wrong please.

EDIT: adding the pros Peter listed

I think they are here:

Hey Rocky,
let me try to understand. You’re asking for the exact size of the gap between riser and barrel for a 6” J-tube?
And then you give an (AI generated?) answer for it in your own post?

Hi Wendi, welcome to Permies!

I hope you'll find an answer soon.

What exactly are you looking for?

M, it's basically a big stratification chamber. So I don't see why it wouldn't be possible implementing it with a rocket powering it.
It would probably have to be a big one in order to put out enough energy to heat up such a big slab. And it would be difficult to start when cold. But I think it could be done.

Thanks for all the valuable input.
I'll draw up 3 options for the costumer.

- classic J-tube with barrel left at the exhaust, taking down the existing chimney structure

- classic J-tube with the barrel on the right and exhaust on the left, conserving the chimney. problem: no bypass possible

- shorty core BBR integrated into the chimney

Von, what exactly is your question? The video seems to show how it works.

I would be careful cooling down the smoke of a not rocket fire like this, creosote etc. will build up and require maintenance.

Not a bad idea. But what about the barrel "kissing" the exhaust? And no bypass option I guess.

Attached a quick sketch of the room, measurements in cm. Also 1 square is 10cm.
