I've been out of the innovative rocket mass tech for a few years - been concentrating on permaculture and hydro/aqua ponics. But now I'm coming back to see new tech - "bell" tech...bell rocket mass? Russian Bell? I am interested in what this "bell" is.
Can anyone give me a quick over view of what it is? I'm looking over the net and there doesn't seem to be anywhere that has a consistent description or "technical how it works" summary.
I'm very interested in this...but do I still use a manifold coming out of the combustion unit for this? I see the purpose of the bell is to trap the heat and let go of the cold. Does this still allow for heat retention in the thermal battery made of cob?
I'm sure I sound like a dimwit atm - but once I got the concept down it'll sink in...just takes a min since I'm so thick skulled bohemian lol.
Twisted, a bell is a box, made of whatever you want, where the hot gases, being less dense, are pushed up by the denser colder ones. There's two holes near floor level, one for the intake, one for the exhaust.
In it's principle itself, it tends to keep the hot gases inside for a long time, compared to a chimney, or may be even an horizontal pipe. They then get more time to exchange the heat with surounding materials, would it be cob or concrete, stone or whatnot. So you can have a thermal battery. I have an acointance, who has a 9 ton mass for his mass stove. It's multiple bells and channels. With a normal fireplace insert iirc.
Very Very Very much appreciated for the links guys.
So in your honest opinion - is this more efficient than a typical rocket mass heater with a 40 foot thermal battery? Not entirely sure that my joists - even though supported underneath with thick barn beams - will hold all those tons....
Bells have very little resistance, while long runs of stove pipe through mass have a lot resistance. Bells can have much more inner surface than the resistance of pipes would allow, thus bells are a lot more efficient.
Well, I suppose I'll try that shallow bell design in my thermal battery then. I'm gonna have to do a lot more research. I'll have to put up pics on my other thread - my mid michigan one - and maybe if you guys have time you can give me some pointers. That animation really allowed me to conceptualize it better. My first thought: how come I didn't think of that? lol

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
