[Stoves] Torrified Pellets

[Ronald Hongsermeier]

Dear Paul,

Have you contacted:
http://www.integrofuels.com/nucoal/request-a-sample/
?

Everything I have read has the pelletization process after the 
torrefaction. I am a little surprised at this, having assumed that 
partial lignin liquification is what provides the binder in most 
pelleting machines and that the lignin will be destroyed for the most 
part in the torrefaction.

I'm not seeking anything at the moment, but may do some experimentation 
when I have more free time. Not likely before I retire.

regards,
Ron
P.S. I have spent a couple hours just now trying to run down an 
operating plant here in Europe and the development speed seems congruent 
to the movement of tar through a cooling pipe in a dormant gasifier.
