[Stoves] Is there a role for combining torrefaction and char-making stoves?

[Crispin Pemberton-Pigott]

Dear Paul

 

Thanks for the concise (distillation?) of facts about torrefaction. Just one
question:

 

Torrefaction greatly reduces the amount of power needed for pelletizing.

 

Can you give us a reference on that, or if not, can you suggest a general
rule about the reduction in energy requirement? That would be a valuable
number to remember.

 

The point about processing of fuels is very reasonable. In the South Africa
they make paraffin out of coal. Zero sulphur.

 

Regards
Crispin
