TSR inverse Aryan with sliding door

[patamos]

Hi Folks,

Just wanted to say that I finally got around to converting my tauran dual throat triple shoe box to a single central port aryan, and it is burning WAY cleaner. The whole middle shoe box is now glowing bright orange by mid burn, and the prior tendency to over-fuel every now and then is gone.
I guess we all kind of knew this aryan triple shoe set up was cleaner. So I'm just adding in some anecdotal evidence. Everything else about my stove's build and my fueling habits has remained the same, but it really is now burning way hotter and cleaner.

Thanks for the update, Pat.

Do you get much flame going around the shelf up into the top chamber?

*(For anyone who doesn't understand Pat's reference to aryan and tauran, it refers to the direction of the double vortex spin, aryan: from the center outwards, tauran: from the outsides in towards the middle, as in the symbols for those signs of the zodiac. Eg. first 2 symbols top left: www.fontscape.com/pictures/page-studio/Astro.gif )

Ya i've been playing with it a bit.
The original dimensions of the middle shoe were 4" tall by 7" wide. The most recent iteration of the dual port set up was two openings at 4.5" long by 1.75" wide.

When I switched to a central aryan port I went with 2.25" wide by 4.5" long (left it at that so I wouldn't have to deconstruct the ceiling of my firebox). Although it burned very clean it also wanted to backdraft out the firebox door a bit; so to clear the restriction I raised the middle shoebox ceiling to 4.5", and opened the port a bit by sliding the bits of kiln shelf (that shape the port opening) forward to make about 3/8" space across the back floor of the middle shoe. In plan view it looks like an uppercase 'T' with a very thick stem and very thin line across the top.
That combination of tweaks has solved the back drafting issue, and when we get into peak burn the flames jetting up the back wall create a forward pressure on the dual rams horn that pushes the flames up into the upper shoebox. When things are really cranking the trajectory of the rams horns is about 45 degree angle.

I should probably widen out the sidewalls of the middle shoe to the specs for a 6" system you have shared. And maybe close off that gap across the back to see what happens.  But that will be another day.
For now I am just thoroughly impressed with the improved performance.
I think it has much to do with the one port offering optimized combustion earlier and later into the burn.  With two ports the size I had them, the phase of optimized combustion was much shorter.
