[Stoves] Stoves Digest, Vol 20, Issue 24

[Thomas Reed]

Dear ADK:

The process of Yuri burns some of the biomass to create the heat for the 
rest. 

In our Toplit Updraft (TLUD) stove and charcoal maker we burn the 
volatiles in a much faster process.  I doubt whether most opeople 
understand the difference, but it is much simpler and cleaner.

Yours truly,

TOM REED
