Crispin,
Excellent report. Of course more info is always requested, and the
ultimate is for testing to replicate the results. We know that will
take some time, but let's push forward.
After all, the GACC has only until 2020 to reach 100 million households,
and that is only 20% of the global need (and probably the easiest 20%
with the most money). In other words, those who have some financial
muscle should get crackin' with support for things that are NEW AND LOOK
VERY PROMISING!!!!!!!!!!!!
And I suspect that these stoves will even be profitable and commercially
viable, which seems to be in the highest priorities of GACC and ACESS.

Dear Paul A
Here is a result from one of the unreported TLUD coal burners tested
recently which I can share a little of without identifying it.
This is a medium power stove capable of heating a small home. The
heating eff was not spectacular -- under 80% though at high power it
was better. That is not unusual.
The burn was 3 hours. It was net negative on PM 2.5 emissions the
last 2 hours, almost exactly, cleaning the ambient air (52 µg/m^3 )
down to <15 µg so not /quite/ perfect. In fact that was all PM1.0.
Total PM2.5 was slightly less than 4 mg per Net MJ of heat in the home
for a saving of 99.4% measured against the baseline. I expect there
will be 4 products in this range, all TLUD's.
The CO was reasonable at 3.3 g/net MJ (space heating).
The fuel was Baganuur coal with about 20% moisture. Volatiles are
about 50%. It is very friable -- I have pulled fronds out of it. It is
layered and does not break nicely into pieces, more like sections of a
book. The only stove I have seen burn it cleaner is a downdraft stove,
fairly large, maybe 10-12 kW which ran red hot.
So, there are some real numbers the wood burners can shoot for.
Regards
Crispin
