Hi everyone here,
I'm new here and new to fora, so bear with me please.
I decided to post here to gain knowledge before embarking on my build (propably next summer) and share eventual results.
The proposition is to build a Bell Batch Peterberg Mass Heater or something to that effect.
Two special items I consider: 1.I'd like to cast the burnchamber and riser with geopolymer cf. Karls thread on the subject.
2. Using the original chimnet as a bell.
This is a first thread intended to clarify the second question.
So here goes: Has someone knowledge of this having been done?
Obvious problems are 1.soot deposits already present in the chimney, they will interfere with leakproofing I think. Solutions anyone?
2. The size of the thing. Internal Surface Area might just be too much. Might possibly be solved building a 8" system instead of a 6" one.
What I imagined was exhausting from the stove at the base of the chimney (which starts at 1,8m heigth from ground floor level. Then exhausting to exterior via steel pipe inserted via chimney top: this would pickup colder fumes from the base of the chimney, a little below entry point of the hot fumes. This would make a "russian" bell.
I know it seems foolish, but I have to check out if it really is and, even then, if it's realizeable.
So any ideas and comments are welcome.
Finally a word of thanks for all you participating members here, it's been a fine adventure reading up on the stuff you all got going here. Fabulous!
