6. Fuel
Specified fuel is dry chopped log fire wood, Ø 8O – 150mm, at least two years old, moisture 12% to
20%, caloric power 15 – 17 MJ.kgֿ¹ and log length 330 - 1,000 mm as per boiler type. Fuel dimensions
are stated in section 3 „Technical Data“. It is also possible to burn large pieces of wood waste in com-
bination (max. 10%) with crude logs.
Basic wood burning data
You can ensure maximum output and a long service life if you burn wood which has been left for at
least 2 years to dry. The following graph illustrates the relationship of moisture content to heating
capacity of the fuel. The energy content declines dramatically with increased water contents.
Example:
Wood with 20% moisture contents has thermal power of 4 kWh /1 kg of wood
Wood with 60% moisture contents has thermal power of 1.5 kWh /1 kg of wood
•
Example – spruce wood which has been stored for 1 year under shelter – see graph
