Boiler Operation and Maintenance
Fuel
Use dry firewood for burning. Using wet
firewood will absorb energy during evapora-
tion and remove most of it through the stack
as unburnt flue gases, thus uselessly loosing
part of energy and resulting in soot formation
in the stack.
Firewood is considered dry when the moisture
content is 20 %. Such wood is lighter in
weight and smashing logs against each other
produces a clearer sound.
ECONATURE-40 is mainly designed for
birch firewood which has a length of 50 cm, a
diameter of 12 cm, and a weight of 1.5 to 1.9
kg.
Other foliferous and coniferous woods are
also suitable for combustion but coniferous
woods cause more contamination to the
boiler. Different woods burn differently.
Lighter woods with a smaller wood diameter
will burn better.
