I am interested in knowing if those 11 included what I consider to
be the better versions of TLUD stoves, both natural draft and
forced air. <br>

I have now seen the article, and provide comments ABOUT THE STOVES
SELECTED. This is NOT about the quality of measurements, etc.<br>
<br>
1. For purposes of review comments, I am allowed to provide some
selected information from the publication:<br>
<br>
<img src="cid:part1.C65C41C9.C10D9825@ilstu.edu" alt=""><br>
**********************************<br>
Of interest (to me) are numbers 4, 6, 10, and 11. <br>
#4. Stove Tec Prototype. Lousy choice to be representing TLUD-FA
stoves. This is old by TLUD standards.<br>
It was tested years ago with great results. Only one unit ever
made, as far as I know.. <br>
<br>
#6. Belonio TLUD-FA (or FD) with rice husk fuel. Poor choice.
Again, an older stove that did not go into <br>
[much] production, and using a non-woody fuel when all other
comparisons of solid fuels are wood.<br>
<br>
#10. Although Philips, it is a rocket stove, and not of main
interest.<br>
#12. The Philips high-turbulance fan-jet stove. This is NOT
designed for nor used in TLUD fashion. <br>
<br>
Net result: This research tells us information that is of very
little use and is not representative of the state of <br>
the art of TLUD stoves, whether FA or ND.<br>
<br>

Crispin also guided me to another study by essentially the same
group:<br>
"Polycyclic Aromatic Hydrocarbons in Fine Particulate Matter Emitted<br>
from Burning Kerosene, Liquid Petroleum Gas, and Wood Fuels in<br>
Household Cookstoves"<br>
Guofeng Shen,† William Preston,‡ Seth M. Ebersviller,§ Craig
Williams,‡ Jerroll W. Faircloth,∥<br>
James J. Jetter,*,⊥ and Michael D. Hays⊥<br>
<br>
The solid-fuel (wood) stoves in this study were<br>
"(iii) wood (10 and 30% moisture content on a wet basis) in a
forced-draft fan stove, and (iv) wood<br>
in a natural-draft rocket cookstove."<br>
<br>
Rockets did not do well (and not an issue with me). But the
"forced-draft fan stove" that also was not optimal is <br>
of interest to me. What TLUD-FA stove did they choose? An
"Eco-chula XXL" which is seen at:<br>
<a class="moz-txt-link-freetext" href="http://www.ecochula.co.in/xxl.html">http://www.ecochula.co.in/xxl.html</a><br>
<br>
I my opinion, that was a terrible choice, (large diameter gives
worse emissions, and is not representative of household cooking) and
therefore the TLUD-FA results of this study are not
representative. From the TLUD perspective, this study only
contributed to the PERCEPTION (erroneous in my opinion) that TLUD-FA
stoves are not very good. <br>
<br>
The Mimi Moto TLUD-FA has been available since 2015. That would
have been a much better choice. <br>
And certainly the Champion TLUD-ND (available since about 2008) is
the best choice for that category stove, but is never included. <br>
<br>
FYI, Except for the BEIA project in Uganda with the Mwoto TLUD-ND, I
have never been asked about what TLUD stoves might best be include
in testing or in research projects. Never. Not by EPA or CSU
or Aprovecho or Berkeley or D-Lab or anyone else. <br>
