off on other topics back in 2006-2007 when all of the stove archives on this

style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">Look
for their meat grinder. If you have a cake or meal like fuel you can make a
wet meal and extrude spaghetti-like pellets that are cut off as you make them.
Then dry it. You end up with a dried lump like Jeff Davis’ fireballs – a low
density but nicely shaped fuel pellet. Dog food is made the same way.

use the technique for making pellets for fiber and seed mixes but there is no
reason why you can’t make fuel pellets that way. We have seen this technique
used for cooking stoves in small projects in India and China. </SPAN></P>

<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">The
advantage for a stove fuel is that making a wet meal and drying it is a low
energy process. When we used to make ag pellets with binders we probably used
about 30-50 kWh/ton. In the 1980s pellet mills were re-designed to make dense
fuel pellets that depend on heating the fiber to 90 C in the die to enhance
adhesion through hydrogen (paper) bonding and lignin flow. Specific power
consumption increased to 75-100 kWh/ton in the pellet mill because yiou are
converting electrical energy to heat. Particles need to be dry (<8% MC) and
fine (<6 mm) to make a good pellet. Christa has a small, capacity, mill
that makes fuel pellets in this way. There are also the Chinese mills with
vertical dies that can be used. </SPAN></P>

Jeff Davis’ fireballs? He put wet fuel into a cement mixer, rolled it into
balls and dried it out. He showed that it made great fuel for a TLUD
gasifier. Why not a stove?</SPAN></P>

<P class=MsoNormal>In my previous email I concluded by
saying:<BR><I>What's needed above all else, in my opinion, are small,
beautiful TLUD's that make use of pellets. Such units could be situated
in modern kitchens throughout the world. Once these units are in place,
the rest will follow.</I></P>

<P class=MsoNormal><BR>It seems that Home Depot, Wal-mart, Lowes, Ace,
Agway and many others large retailers in the USA all carry wood pellets.
Why can we not make TLUDs that make use of these pellets as fuel? The
only thing that changes is the height of the reactor: it's much less
than the height of a reactor that uses undensified biomass. This means
that the TLUD is small, lightweight, mobile and much
cheaper.<BR><BR>Here is an example of what I am talking about:<BR><A

<DIV>
<P class=MsoNormal>This reactor holds about 2 kgs of pellets.</P></DIV>

<P class=MsoNormal>We've already tested taller TLUDs on rice hull
pellets,</P></DIV>
<DIV>
<P class=MsoNormal> and they emit the same beautiful blue flame as
when loose rice hulls are used.</P></DIV>
<DIV>
<P class=MsoNormal>Another big advantage of pellets is that there is
much less particulate matter emissions compared to loose rice
hulls.</P></DIV>
<DIV>
<P class=MsoNormal>Loose rice hulls are dusty, messy, bulky and a real
nuisance to store and load.</P></DIV>
<DIV>
<P class=MsoNormal>In an urban setting it makes no sense to be hauling
in loose rice hulls of a bulk density of only 80 kg/m3.</P></DIV>

must reach a certain level of convenience and ease of use.</P>

<P class=MsoNormal>In may cases transport distances are short, and the
economics are quite good, and yet we complacently continue to burn
fossil fuels. I lived for over 20 years in West Flanders in Belgium
where wheat fields encroached upon densely populated rural areas, and
yet everyone merrily burned LPG gas to cook a meal. Later I move to
Waxahachie, Texas, a small town near Dallas, and once again, wheat
fields were everywhere. Yet no one dreamed of making wheat husk or wheat
straw pellets and using them to make syngas to cook a meal.</P></DIV>

<P class=MsoNormal>China appears to be struggling with a lack of
infrastructure in getting pellets to market. How does one explain the
economics of shipping coffee husk pellets from Brazil to Holland as we
see in this link? <A
href="http://www.coffeehabitat.com/2007/10/coffee-husks-as/"
target=_blank>http://www.coffeehabitat.com/2007/10/coffee-husks-as/</A>
This is a thoroughly bold undertaking, but does it make sense to
transport coffee husk pellets half way around the world to provide fuel
for Dutch power stations? Why not make use of these pellets in Brazil?
Also, one might argue that the highest and best use of coffee husk
pellets would be, not to burn them in huge power stations, but to
generate from them a syngas that would replace bottled gas or other
forms of fossil fuel gas. The biochar left over from these stoves would
then be returned to the soil.</P></DIV>
