I have already read about temperature in the heat riser, but not further, in the bench.
What is the temperature just after the barrel, after the ash tray, when it goes into the bench pipe?
What is the temperature 1-2 meters further, and then further on?
How fast does it go down along the way?
I think I never saw anything about this, so,
(more over than the difference for sitting between the beginning and the end of a bench)
How far from the barrel can I use some ordinary red brick for the smoke inside the bench?
I want to build the bench gas canal, or else I would have to buy some expensive pipes (I live in an island...)
I would start with refractory bricks if needed.
I can also use stone with refractory cement.
The cheapest for me is what we call "bardo" of "termo-arcilla", the hollow red clay brick,
because they exist in a large size of 1 meter.
I would fill them where I do not want them to insulate, and leave them hollow on he ground, and may be on the sides, according to what is best.
(I have found some local light stone with air bubbles to insulate from the ground.)
I do not want bricks to crack because the temperature exceed what they can stand!
Thanks for any
experience and known measurements.
