Vons 8" BBR

Hey all! In the next week or so I need to build a 8 inch batch box and I need the design template. Where can I get it?

Von, Looks like you started two different threads searching for the "answers", with Dragon Tech already giving you the dimension basic page.  Depending on the details, you would have much to do, before NEXT WEEK, depending on what you have available.  Along this line would be some questions to be answered only by you.

- fire brick size
- bell brick size, single layer bell or double, with bench or not
- extended batch chamber or not
-  standard batch with riser, sidewinder, or perhaps the latest, the shorty
- right, left or rear exit flue
-raised burning unit or base level
-size of glass on the door or no glass at all

This is not to discourage you, but rather helping you to formulate your game plan as these stoves are rather perminate in nature, and certainly can't be moved once done.  Best of success.

Scott I don’t even know what all that means!! Why do I need to know fire brick size? I’m gonna do a little research what you given me though, best if I can talk to someone. I will have a 110 feet of bench and in the ground. For the bell I want to make a chamber for ceramic. What’s left right rear exit? My main concern is how do I insulate the pipe under my ground in the greenhouse. Like what materials should I use and how much. Thanks Scott for your time.

Von, I will touch just a few of the basic's on the "need to know and reasons for them"

1) You stated you wanted to know the layout of a 8" system, But you did not say where you intend to have your flue? So I am trying to figure out, how you interput any layout suggestions to match what you want to do? That was why I said that.  or rather bluntly, have you ever heard of anyone that has done what you intend to do?

2) If you don't know any of the answers, to the various options you can have for a 8" unit, I refer back to number 1, everything is so important, and depending on how you intend to experiment, None are super easy to simply change to something else, if things don't work for you. again, not to discourage you, but have you seen this work? ( what you intend to do ) and to jump in "next week "

3) 110 foot of bench?  Do you understand the basic's of ISA (internal surface area)  and how it relates to the overall operation of the unit? Lets say you really do attempt to have at minimum this 110 of bench, Do you understand what happens to the flow of the hot gases, when cooled beyond 140 degree's?

4) you mention you would like to talk to someone,  if you were to do that, and everyone was honest about it, I am thinking 1 to 3 items would all need to be discussed, thus the reason for my statements in the first place    Just trying to be helpful, in saying there is a lot more to what you want to do than simply understanding how to insulate what I presume is below the 110 foot bench.

5) lastly you mention, a chamber in the bell for ceramic?  Again, I mention, the need to understand  how the forces of hot gases make the system work, ( extraction of BTU's)  while a 8" system can be mighty powerful, if you defy phyics, you will likely come out on the short end.

So where would I start?    The very first thing I would do, is find someone that has even remotely done what you intend to do? There is no shame in replicating  a known system that works. VS having a system that simply will not function.   I hope someone steps forward that has such.

Best of success.

Thanks Scott you been very helpful. I guess this will be my battle alone to experiment. At any rate if I fail I can just redue again. Thanks you all for attempting to help!
