Hi All,
Thought i should share my almost finished build. Still some tweaking and finishing to do, but it has been burning all winter and it seems to be holding up! (Thanks to all the tips and knowledge on this forum btw.)
Its a 15 cm system with a S port. Mostly build with adobe bricks and adobe mortar. There is an heated bench bell and its connected with a custom made bench with custom pillows. The topbell is temporary and made of silicon fiber board and fermacell board for reenforcing. This was done to keep the weight of the stove as low as possible (to not tax the flooring of the house too much) Later on I made the heatriser a bit higher as i discovered the optimal height was 20 cm more then i originally planned. I used insulating firebricks for that and to increase the height of the bell i cut the top open and placed half of a 100 liter barrel on top.
I have a double insulated 15 cm chimney 9 meters straight up, draft is fine!
Plan is to remove the top and make the riser shorter again as i am inspired by the recent experiments on that topic. The top will then be replaced by a 200 liter barrel that i probably will cut in half . If that works i will finish the stove with adobe plaster.
Mistakes:
The burnchamber is probably too big. i made some mistakes with transferring my sketchup drawings to the actual build and made the door too high. As it also is too wide (on purpose, because i wanted a good view on the fire) the opening is way too big. The part of the burnchamber near the heatriser has the normal measurements though. It burns quite well, but as i dont have testing equipment at my disposal i am not sure how clean it is burning. Exit tempuratures are 100 degrees max, so efficiency seems ok?
Dont like the silicon fiber boeard at all, its quite weak and i get this asbestos vibe from it. At the time i wanted to get the stove burning and it was the quickest option, but now i regret it. I do like the insulating firebricks however. They are really great to work with. I made the last part of the heatriser with them and the firebox, which i plastered with the glue to get an abrasion resistent inside.
Here are some pics of the building process and the finished build: (in Vortex's post)
