Hi all,
Following
this thread and some of the mods there, here's my design which I surely could use some feedback on. In any case, I will report back on whether it worked.
In short:
it's an outdoor rocket mass heatermaximizes exhaust
The image might explain a bit more.
The Top View shows that there are two exhaust sections.
Section A: the main exhaust, which is already rather lengthy given the sizing of the stove.
Section B: the secondary exhaust, which is (as shown in side view) raised to heat the back of the outdoor '
cob sofa'. This exhaust passes through the bell, which is supposed to heat the exhaust and create an additional pull
Bypass starter: is an opening directly into the bell, to start the
RMH and is closed once heated
enough to push the
RMH
As one can see in the side view, the idea is to insulate the bench entirely except from the seating part and the back. This is to maximize the heat going to the seating area when outdoors.
What I'm concerned about is the dimensions of CSA and whether it can push/pull enough air to bridge the length of the first exhaust. Honestly, I hope the second works, but that is less crucial. It would be simply be cool to get the second going as well. If the first would work, I already would be happy enough.
