Dry DebarkingCosts & Benefits
|Parent Process: Virgin Material Preparation|
|Energy Savings Potential||
Energy consumption in debarking might increase due to the operation of debarking drum in dry debarking mode. However this energy increase is entirely offset by the substantial amount of energy gain if the bark is used as an auxillary fuel due to the lesser water content in bark from dry debarking.
|CO2 Emission Reduction Potential|
Typical investment costs of a new dry debarking system from log feed to conveyors is about €15 million for a capacity of around 1300 ADt/d kraft pulp. The conversion of an existing wet debarking system to a dry debarking system costs €4 – 6 million, for equipment and installation. perating costs are € 250000 – 350000 per year
