[Stoves] Thanks for the info

[Kelpie Wilson]

Hello all,
Sorry for late response, I get the digest and could not figure out how to
respond to individual messages.

Anyway, thanks Crispin, for the suggestion of a rocket mass heater with
down draft heat exchanger. That's a great idea. TLUDs tend to draft too
fast and you lose a lot of heat up the stack. That's why I don't use a
stack on my 55 gal TLUD. I just use another barrel on top to make a plenum
burner - it has slots around the top for the flue gas to escape. Burns
super clean. See one here, burning hemp stalks:

Andrew and Gordon - TLUDs are not desirable for this application because
what we have is cord wood and we don't want to chip or pelletize it (even
though your TLUD BBQ that I have is very nice, Gordon, it uses pellets).
The cordwood is mostly being used for biochar production in flame cap
kilns, but as long as we are doing all that feedstock prep, it makes sense
to use some just for fuel. I don't really care about making biochar in this
case.

Francesco - yes I remember meeting Lowell at the Permaculture Convergence
last month - very nice what he is doing and looks like he is using wood
chunks in that TLUD? Or is it wood chips? Maybe a TLUD that used long 24"
pieces of split cordwood (2-3" thick), arranged vertically, would work. Is
anyone using this kind of small size cord wood in a TLUD? Seems better
suited to a rocket stove.

The dairy needs 30 gallons of 150 F hot water twice a day for cleanup after
milking, plus more every few days for pasteurizing. I recommend they
install a solar pre-heating system so a quick hot fire started at the
beginning of milking and fed during the hour-long milking process would get
that water up to temperature in a reasonable amount of time.

Francesco - did you meet a guy at Permies who does hydronic and solar
heating systems? I had a long talk with him around the biochar bonfire
Saturday night, but I don't remember his name. I'd like to contact him.

Rolf, thank you for the link to your retorts - those look like high-quality
units.
