<DIV><FONT face=Arial>Dear Pete</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I would suggest that a simpler, and better way to evaluate
wood chips is to use a "Two Screen System." For example, if you used
square mesh screen with 1/2"x1/2", and 1"x1" openings, you would end up with 3
products:</FONT></DIV>
<DIV><FONT face=Arial>1: +1"</FONT></DIV>
<DIV><FONT face=Arial>2: -1", + 1/2"</FONT></DIV>
<DIV><FONT face=Arial>3: -1/2"</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>The APA Gage is intended for a different purpose... to
give a reflection of wood fibre length, because that is what is important to
Pulp Mills. For gasifier applications, uniformity of size, and the percentage of
void space is what is important. The "two screen system" should give screened
chips from "between the screen decks" that are much more uniform, and having
much better gas flow characteristics.</FONT></DIV>

<P class=MsoNormal>My only interest for gasifier fuel is wood chips. If
I can’t understand them and make them work well, I won’t be using a
gasifier at all.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I know this may be old news to many of you, but I recently
found a couple of ways to characterize wood chips. Although there are
plenty of good systems out there the best ones are way to complex and
expensive for me. <o:p></o:p></P>
<P class=MsoNormal>So, I am using a simple gauge from the APA (American
Pulpwood Association.<o:p></o:p></P>
<P class=MsoNormal> My simple page to explain the process is
at:<o:p></o:p></P>

<P class=MsoNormal>It has links to a couple of in-depth sources for
understanding wood chips, too.<o:p></o:p></P>
