chemical treatment or other mineral or organic substances)
o
the length of the wood logs must correspond to the depth of the combustion chamber of the
boiler
(see boiler technical specifications)
o
the crosswise section (diameter) of the wood logs must be: D
≤
200 mm
o
the raw material humidity content must be less than 20% (W
r
≤
20%)
o
wood-based fuel such as sawdust, wood chips and other small combustible particles may be
