There is a window but I do not recall what it is.

Not sure about the bark but the course sawdust should be OK.

In the "Technology Packages: Screw-press briquetting machines and 
briquette-fired stoves" it says about 320 deg C, that's for rice hulls. They 
have on line books on making these machines. I do not have the URL in front 
of me but some key names to google are, Bhattacharya, Asian Institute of 
Technology, technology packages, RERIC. One of the book ISBN numbers is 
974-8202-976

In regards to agglomerations:

Right now my main interest is in hydrogen bonding.

You might want to check out my outdated web page at the below link:

If you go to the below link and look for fuel then look for fireballs you can 
read somemore.

High density pellets make great fuel and if you need to transport your fuel it 
is the way to go. But I like to think about biomass as the common (ground) on 
an electronic PB board and the transistors and IC's are like coal and oil. So 
if possible use biomass at or close to the point of use and now a low density 
agglomeration starts to make some sense. In other words, people like to apply 
old oil/coal thinking to biomass. Oil/coal has to be transported because it 
is not common, it is found at remote locations and needs to be transported. 
There are lots of odd biomass fuels that are under our noses that we can use. 
We need to unify these odd fuels. That is my hope for the fireball.


Best wishes,

Jeff
