Jason,
I've taken a look at your website and the info about the
"IntensiFire", however one of the main points of the project will be to
produce biochar (for use with the compost that they are already
making). If the IntensiFire is only meant to increase efficiency and to
reduce emissions for wood burning stoves, this may not be quite what we
are looking for, although it might be possible to "adapt" the
IntensiFire to the application in some way [?] (in order to maximize the
efficiency and minimize the emissions) ~ although the total cost might
be quite prohibitive, given that the IntensiFire (Mk II) is already
starting at $499 NZD (not including shipping all the way from NZ to Canada).
I will, however, keep your downdraft technology in mind as we move
forward with our project.

Dear Lloyd,
what you require sounds like a possible application for the IntensiFire.
I can't promise you open source or off the shelf, or even the capacity
yet to build what you are after. Probably won't get much biochar either.
What I can offer is super clean combustion (zero CO and possibly zero
PM10) particularly with auger fed fuel to keep combustion in the sweet
spot. I have also built a prototype woodstove that will burn green
wood with no visible smoke.
Kind Regards
Jason

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.)
