<div class="moz-cite-prefix">Dear Yibo, and to Ron and all,<br>
<br>
It is great to have direct contact with colleagues in China,
especially those who can communicate well in English (sorry that
most of us have no functional abilities in Chinese).<br>
<br>
I call your attention to the PhD program at the University of
Illinois, with attention to Dr. Tami Bond who has some of the best
credentials anywhere for studies with gasifier stoves. <br>
<br>
I am Paul Anderson, PhD., a retired professor from a near-by but
different university in Illinois, so I have no personal influence
about acceptance of PhD candidates. But I would love to work with
you, even if informally. <br>
<br>
Advice: WHAT your propose to study in your PhD work is extremely
important. If it is of sufficient interest to others, the
funding of your studies is much easier. If you have financial
support from China, then your situation is vastly different (and
easier) than if you are also seeking money. Please send further
information about your possible topic(s) and funding options.
You can reply privately to me, but I believe that sharing your
info with others on the Listserv(s) would be of benefit to you.<br>
<br>
By the way (to Yibo and all), there is considerable interest in
the USA about <b><u>heating </u></b>with woody
biomass/pellets/etc,. including a possible special week at
Aprovecho this coming summer (probably mid to late July).
Research about gasifiers (all types) for
residential/small-business heating could be a highly appropriate
topic. (Yibo needs to inform us of his academic
specialties/trainings/interests. He could be anything from a
chemical engineer to a social scientist with experience with TLUD
stoves. ALL are welcome and highly needed!!!!!!)<br>
<br>
Prof. Anderson <br>

is a highly skilled TLUD (for cooking not heating) researcher at
one of the major Chinese Universities. He is looking for a PhD
track in a US University. If anyone knows of an interested
faculty sponsor, I can recommend Yibo highly as already knowing
a lot in this area. He has spent considerable time already in
the US.</div>

Dear Professor,</div>
<div> </div>
<div>Sorry for the delay...</div>
<div> </div>
<div>According to my limited knowledge about the TLUD stove
in China, the evaluation of the performance is something
related to at least three factors, the stove,the fuel and
the user behavior. In China, the factory can produce
different size of pellets, 8mm, 15mm and 30mm. </div>
<div> </div>
<div>My lab have 8mm diameter pellets (the moisture is about
9%) and the natural draft TLUD stove can achieve CO
emission factor 3.53±0.49 g/MJ and PM emission factor
258.15±26.21 mg/MJ with this kind of fuel. The data can be
seen in the MC manuscript. TLUD stoves with fan can
achieve lower emission with proper air control.</div>
<div> </div>
<div>In term of bigger pellets which is produced for heating
stove, I never tried before with the stove in my lab
because I have not started to test the heating stove yet.
But I've seen people using bigger pellets for heating in
Liaoning Province. I measured the emission from the
chimney and most of the average CO concentrations are
between 100-300 ppm (no PM data, unfortunately). The stove
they are using is designed with a fan which is only for
the secondary air. </div>
<div> </div>
<div>I think in the same stove, fuel in smaller size means
more gasifying area and more combustible air or VOCs
produced during gasification per unit time. With the same
air provided, larger size fuel seems burn more slowly than
smaller fuel, which may lead to cleaner burning due to
enough secondary air feeding. But I just guess...I have
never tested one stove using fuel with different size and
made of the same biomass. </div>
<div> </div>
<div>And of course smaller size fuel light more easily than
fuel in larger size if they were made of the same
biomass. And good recipe plays important role in the
gasification rate. </div>
<div><br>
Best wishes</div>
