Papermaking PAPERMACHINE – DRYING Introduction

Paper machine dryers have been modelled using computers and rigorous application of heat and mass transfer principles. However, there is often a need for some simple estimates of dryer sections of paper machines. In this case, data compiled from industry averages are frequently used. The TAPPI drying rates shown in Figure 14 are one source.
