Paul,
I did understand that what I was describing was very similar to what I
observed Chip Energy factory site during CHAB Camp, and so I have been
thinking of something similar ~ yet not /exactly/ the same, because we
don't necessarily need a "full big system", although one important
aspect would be to have the "heat exchanger/water pump, etc.", which
(incidentally) I never saw in operation while I was there in 2010.
Since you say that the unit "it is not a 'plug and play' system" (I
did fully understand that it is a "project", and certainly not just "a
turn-key product"), and that it would require "support including some
R&D for the specific application/location", this is in fact what I
should be able to provide -- as an "engineering technologist", this is
what I do best -- and given my background in factory automation and more
recently in supporting the bioenergy and biochar industries over these
last few years, I believe that (given a bit more training... and time on
the system getting familiar with its nuances) I could easily provide
this type of project ans system support [and training] for this
particular client (as well as for any future systems as they are
deployed in cities and towns across Ontario/Canada or elsewhere ~ once
the 'core technologies' for this specific application -- and/or other
similar applications -- have been developed and fine-tuned, in
cooperation with both the client and the technology provider).
Note: In my communications with the client I have made it clear, and
they do understand, that there would be some expense in terms of initial
R&D since these types of specific systems [applications] that they are
asking for have (as far as I know) not been "commercialized" (as yet).
They do seem to be quite willing to "break some ground" on this however,
and seem to have some funds (and enthusiasm) that may allow us to move
forward with something (however small or crude the system might be,
initially).
[Your experience with chipping/grinding waste feedstocks like pallets
sounds like it would be quite useful as well, to help prevent repeating
any 'mis-steps' that might have already been overcome by others.]
P.S. I rarely ever change the Subject line... although I know that I
probably /should/. (To me it's the /least/ important part of the message
and I rarely pay any attention to it.)
P.P.S. The only other "candidate (technology)" for this particular
project that has been discussed (so far) was the suggestion made by
Crispin to use the "Wood burning BLDD 6" system from the SeTAR Centre In
Johannesburg, although I am not certain [it was not made clear] whether
that system can easily extract the biochar.
Note: We are also _not_ looking to make a "Cookstove", but rather, are
seeking ways to heat water and/or use the system for "roasting" their
specific ingredients (@ ~140 Celsius max.).

Lloyd,
1. You should change the Subject line to reflect the topic.
2. I think Crispin is not subscribed to the Gasification Listserv, so
I am sending my reply plus your message to him.
3. What you describe (including making biochar) is most closely met
by the Chip Energy Biomass Furnace. See www.chipenergy.com The
realities are:
a. $50,000 for the full big system; To fit on a pallet-size
footprint, the $15,000 for the stripped system is without heat
exchanger/water pump, etc.
b. With 4 units commercially made, we know that it works. However, it
is a unit that should have support including some R&D for the specific
application/location; it is not a "plug and play" system.
c. Your expectations about using a wide variety of dry biomass fuels
would require R&D at the expense of the operator. Fuel from shipping
pallets sounds easy, but the metal nails and bolts prohibit "chipping"
and require a grinder with magnet to extract the metal (significant
effort/investment).
Chip Energy is interested in such a project, but it is a project, not
just a turn-key product. Contact me for further details.

Please let us know if there are other candidates for that project.

Crispin (and all), [CC; gasification list]
This is a very interesting conversation regarding ND TLUD power
(heat) variability and its implications, and (as you know) I do have
a keen interest in this topic since being introduced to the TLUD
'stove' concept back several years ago (by Dr. Anderson, when he came
to Ontario to demonstrate his small "Champion" stove and similar
devices at the Laepple farm in June 2009), especially since the TLUD
is one of the few simple technologies that can produce biochar
cleanly at a small (or possibly at a medium) scale for local use ~
while producing (hopefully) useful amounts of energy (heat).
What I am working on right now here in Toronto might interest you
or others on this list.
I have been approached by a business in Toronto that would like to
be able to implement a small-scale char-making technology at their
manufacturing site in the Toronto area (GTA) that would utilize the
(dry) 'residuals' from their food production process in order to make
heat energy that could lower their (fossil) energy use [natural gas
costs] while also turning their (dry) 'food waste' into a biochar
(and/or high-char ash) that could be re-integrated back into a (wet)
food composting system (vermicompost) that is already being
implemented onsite at their operations here in the city.
The primary use of the heat would be to heat up water, but it would
also be welcome if it could be used in the preparation of the 'raw'
food (drying, roasting certain products to a certain temperature --
i.e. an 'oven') that goes into their recipes, which includes
'fair-trade' sourced (temperate and tropical) foodstuffs that have
been either grown or imported into Canada in bulk, and which are
prepared on-site (including de-hulling etc. of several of the key
ingredients).
Essentially, this company would like to know if it might be
possible to come up with either a "customized" or an "off-the-shelf"
system that has a fairly small footprint (about the size of a
shipping pallet <http://en.wikipedia.org/wiki/Pallet#Dimensions>, or
~16 sq. ft = 40" × 48", as commonly used in the food industry) that
would be able to meet the following requirements:
* Provides space heating and/or hot water heating (for their
kitchen), with the possibility also for using the heat for
"roasting" their ingredients (@ ~140 Celsius max. -- possibly
using a heat exchanger, if necessary).
* something flexible and rugged
* can accept multiple fuel inputs (different sized feedstocks,
different moisture/energy content -- not just woodchips)
* no smoky emissions (after-burner, if necessary) so that it can
meet local emissions regs
Of course they are interested also in custom of "commercial"
gasifiers [as well], but small systems (stoves) that could do the job
they are seeking might suffice, although they probably want the
system to be as automated (hands off) as possible to that the minimum
amount of human intervention is required... although it would need to
be as low-cost as possible (almost a "DIY" system -- they could
actually make it themselves since they do have some expertise,
including a machinist & a "master builder" who has built and operated
a series of gassifier stoves for several years and "who is more than
capable of manufacturing" something -- if they had the 'plans' for an
open-source system/design that could do the job).
Ideally this company would be interested in seeing 2 or 3 designs
that might work for them (a few devices that they could initially
assess)... so that they could work with the designers to get more
details. They would then choose a final design that they would then
incorporate into their head office (operations), but then possibly
also into a "franchise system" that they are designing (and that
would operate like a "food truck" would in /any/ city ~ except
instead of the truck being electricity or natural gas or
propane-powered, the 'portable' food production/processing system
would operate partially off of its own 'waste'... and/or wood chips
[or pellets] that could be produced or supplied locally ~ possibly
even from chipped shipping pallets that have /only/ transported food
products -- i.e. clean, 'food-grade' "green waste" like the type that
can be found at the back of nearly every supermarket in the
country... including all the broken ones.)
