Digester Screen Modification

In order to increase the screen area in a set of digester screens used in the manufacture of pulp from cellulosic fibrous material, the blank screen plates in the digester step-out area are to be replaced with extended diagonal screens.

This extension increases the screen area by a significant percentage, in one design at least 30%. The resulting open area increase is about 200% for the design where the screen area is increased at least 30%, which allows screen loading (flow divided by the total screen open area) to decrease.
