Glad to have finally been able to help someone!

Actually Karl, the way I read it says it would not. The draw on an H Cowel has certain aerodynamic properties that a simple T does not. It can actually accentuate the draw when the wind blows from either direction and if rain comes down a simple T during a storm would allow water to the flue, an H cowel would not. That is the way I read it when researching it anyway. I think I will use one for my build, it looks simple enough to build one for ones self and not have to purchase one ready made.

Picking up materials on Friday to start the build. Hope to be finished (time permitting) in a couple of weeks. Since I got no comments on the two part burner idea, I am falling back to the "box style" design. Easier to build a mold but I do think the two part burner would not be a bad idea.

Seems to me, the second paragraph and the last two paragraphs would be best. That is at least how I would do it...

Two Halves.skp (345.36 KB) Had a very productive conversation with the guy at the local refractory supplies dealer. Out of that conversation came this idea I would like to run by everyone and solicit opinions if you will. The attached .skp file incorporates P-Channel, trip wire, inherent in design back sweep and a kick tail all around the riser half of the two part burner. The half with the P-Channel and trip wire to be cast from dense refractory cement (probably in two halves then squished together, which is the only way I can envision doing it, unless anyone has an other idea). The half with the kick tail, since it will not suffer mechanical abuse of fuel knocking it around to be cast from insulating refractory. Proposed joining method (which would allow any angle to be put on the riser section) High Temp RTV sealant, 1/4" refractory paper and a 401 stainless strap/clamp. This would all be boxed up in a container of course surrounded by insulative materials but the two halves would be shippable (another plus to the method) and rather portable too. Comments?

I understand the P-Channel and its purpose combined with the trip wire. A question I have is the implementation of these two innovations in a round feed tube and burn tunnel. Same rule as 5% of the CSA of the feed tube I assume but how would one implement it? Or is it even of benefit in a round configuration? On the other end of things, where it comes to the back sweep, if the round tube is a sweep already (i.e. a curved 90 degree bend) is it beneficial to incorporate a kick tail? In the angled riser when the gasses leave a round burn tunnel they naturally swirl in the riser tube which creates turbulence at that point without much drag. That is the reason for the question. I thought I had asked this question already but I don't see it so maybe I did not after all.

I put a request in for some time off to gather information and materials from a local refractory dealer. This is the guy I mentioned before who might be able to have a monolithic ceramic riser tube made for me. I will let all of you know what transpires after the meeting. He did contact me to let me know I could buy in small portions (less than a whole roll of ceramic blanket material et. al.) and said he would like to discuss the project with me. Fingers are crossed so if there are any typographic errors here, that is the reason, hard to type with fingers crossed.

Just a thought but the wasted space below the barrel could have an open archway and a cradle inside for wood storage. No sense wasting that space in my most humble opinion. I was thinking of something very much like this for my build but with the buffer barrel on it's side. My thought was that more surface area of the coil would then be subjected to the hotter water stratified at the top edge of the buffer barrel. Great design, very self contained and it could process many gallons of water which could then be stored in large insulated tanks for mass. Safe too, the main concern when heating water with solid fuel.

Thanks Pat! I bet it was panic city! I don't think I can use a cast refractory riser though. I fear that if placed on angle in the burner base it might be too heavy in and of itself and either crack itself off or damage the burner base itself. I just found a message from the guy I was talking to locally on my machine last night so a vacuum formed riser of the correct length is not out of the question yet. I thought he would email me and since he didn't I thought he was just going to ignore me so I had given up on it. He actually picked up the phone and called though! I really need some time off work to go see him and discuss this with him.
I shall keep y'all posted!

Well, since nobody said my idea about forming my riser as I previously posted would be a bad thing or would not work, I will order the materials on Friday. A bit more expensive than I expected for the Cerablanket but I will have material left over for future use after the riser is completed so I don't think that is a bad thing. I did a bunch of calling around and just could not find anywhere local that had the Cerablanket and rigidizer. I could have had lower temperature wool but I would rather over than under engineer anytime I possibly can. I just don't like to settle for less than what I want. It is just not like me.
