Table 3.1 Conservation Of Energy In Wood Raw Material Handling, Chipping, Wood Chip Screening
No Activities Energy Conservation Investment
1. Avoid log blocking at chipper
feeding
Avoid unload machine operation No Investment
2. Minimize the chip pile high Avoid heat due to the pile No or small investment
3. Follow fifo procedure (first in
first out) in storage chip pile
Chip will stay at the same time and the
same degree of degradation
No or small investment
4. Put Chip in chips silo Reduce wood loss Silo installation
5. Apply Cradle Debarker Reduce wood degradation and loss.
Saving energy 30% for debarking
6. Change pneumatic chips
conveyor with belt conveyor
7. Apply automatic chip handling
and thickness screening
Save electrical power from 18,5
kWh/ton (pneumatic) to 1 kWh/ton
(belt),
Supporting fifo management, yield, and
raw materials saving
