The objective of the research is to improve the
combustion technical properties of by-products formed in
mechanical forest industry by developing the fuel storage
and processing. The research is divided into three
subprojects: 1) the optimisation of the storage of bark,
2) reduction of the moisture content of the bark, and 3)
removal of harmful substances from the fuel.
Behaviour of spruce and pine bark in the storage was
studied during a period of three months in the first
storage researches. Main results of the storage
researches were that the barks tested dried 6,5-10,5%
during the storage period and no significant changes were
observed in the calorific value of the dry matter.
Reduction of the moisture content increased the effective
calorific value by 8,0-14% compared to the initial value.
Apparently a significant part of the increase of the
calorific value was lost due to the SD-losses during the
storage. Unfortunately the precise value of DS-losses
could not be measured during the tests.
