Crispin and all,
Wonderful news about TLUDs in Mongolia!!!!!!!! My notes:
1. In general, we Stovers do not know much about the Mongolia
activities because there has been precious little information coming to
us from the people doing the project. (Interpretation: We know that you
are busy, but do not blame us for not knowing about or discussing the
Mongolia stove efforts. )
2. Although TLUD stoves are generally focused on dry biomass fuels,
CLEAN BURNING of COAL is certainly acceptable in my book.
(Interpretation: We could certainly embrace coal as TLUD fuel more if
we did not spend so much time discussing (arguing) about fuel
efficiencies being worse because charcoal is made in TLUD stoves. CO2
negative (bury biochar) vs CO2 neutral (burn trees to ash) vs CO2
positive (coal). Wow, We could argue this forever and never get to
the business of making TLUD stoves, meanwhile the LPG stoves can blaze
away being CO2 positive.)
3. That is an impressive list:
The City of Ulaanbaatar
MCC/MCA Mongolia (USA)
Asian Development Bank
World Bank
Xac Bank (pronounced '_kh_ass')
And none of them can get their act together to divulge about a
SUCCESSFUL project??? Get some of these 100,000 stoves out of Mongolia
and into the hands of SeTAR and Aprovecho and Jetter and even to me or
others. And put a TINY bit of cash behind it to get their success
documented. Certainly the ADB and WB ought to understand that?
No. I doubt it. And the academics cannot seem to see beyond "peer
reviewed" publications that come out months and months later. Crispin
should not have to do this announcement of important results by himself.
4. And as for the GACC Stove Inventory refusing to include the coal
stoves, that inventory exists but is not functional (useful) yet. If
it is, let's have somebody explain how they have used it thus far.
5. For everyone: The Thread (Subject) of this series of messages is
TLUD Use. And then the next words can say where or how. But if the
where is Mongolia instead of the previously name Vietnam, then PLEASE
ADJUST THE SUBJECT LINE!!
I am delighted to read about TLUD success in Mongolia. I just want to
read MORE about it. THEN we can tell others about it.

Dear Paul and All
It may be worth keeping your eye on the Mongolian home stove
replacement program by MCC (Millennium Challenge Corp) which ends in
September though will be continued by the Ulaanbaatar City government.
It has replaced something like 100,000 stoves with a value in the
range of $15m so far. Almost all of them are TLUD's.
The % improvement in combustion efficiency and emissions reduction of
PM, BC and CO has been greater for coal burning stoves than for any
other device and it has not received the attention that it deserves.
The performance improvement was not accidental -- meaning it is the
result of an iterative process of testing and analysis.
It is unfortunate in the extreme that these stoves were not included
in the Stove Inventory because they indicate the level of performance
which can be achieved with scientific testing and sound design advice.
The fuels being used are more difficult to deal with than wood or wood
pellets yet they have achieved much better performance so I think it
is remiss for the TLUD promoters not to be on top of this situation. I
don't think there is another improved stove programme currently going
on with $15m work of product already on the street.
The project is about to step up a gear to include the low pressure
water heating stoves and mass wall heaters both of which were left in
abeyance by the urgency to deal with ger stoves. The organisations
involved are numerous, but I will mention the highest profile being:
The City of Ulaanbaatar
MCC/MCA Mongolia (USA)
Asian Development Bank
World Bank
Xac Bank (pronounced '_kh_ass')
Accomplishments: The reduction in CO is >70% and in PM+BC >90%. There
are fuel consumption reduction benefits though this has been secondary
to air quality in terms of the main goals.
There are >150,000 home stoves in use in the city plus thousands of
other combustors. A complete transition from conventional combustors
to advanced ones will take a few more years. There are two designs
that have proven to be truly worthy of dissemination: crossdraft
burners (which can be hopper fed) and batch-loaded TLUD's. Both are
capable of a 99% reduction in PM and I believe BC which forms a great
fraction of it.

Dear Stephen,
Your research with 100 households is highly important. But I hope
that some of your key results on usage will be made available soon.
To wait until the end of the year to maybe have peer-review
publication before we see the results is a looooong time.
Just knowing the trends or "favorable" vs "unfavorable" will help.
Paul
