Chapter 8. Pulp and Paper
There are several variations in calculating wood requirements, due to the different measures of pulp (short ton, metric tonne) and different measures for the wood raw material (cubic foot, cubic meter, bonedry unit). A bonedry unit (BDU) represents 2,400 pounds of chips or residues. See Chapter 7 for further discussion of chip and residue measures and conversions. Basic formulas are: 4 ...

Wet wood chips are dried in a continuous rotary dryer ...
Question: Wet wood chips are dried in a continuous rotary dryer that operates at atmospheric pressure. The chips enter at 19 degree C with a water content of 40 wt% and must leave with a moisture content of less than 15%. Hot air is fed to the dryer at a rate of m^3(STP)/kg wet chips. To monitor the performance of the dryer by sampling the ...
MOISTURE CONTENT BY THE OVENDRY METHOD FOR INDUSTRIAL TESTING
drying can drive volatile compounds out of some species of wood. When this occurs, the wood weighs less than if just the water had been removed. When the moisture content is calculated, the value is too high. Usually, the more odorous the wood, the more volatile compounds are present. Extractives give wood its color. Generally speaking, the ...
