There are about 40 to 70 dryer cylinders on a typical paper machines, and this is by far the largest part of a papermachine. Drying Page 5 . The dryer cylinders are grouped in sections having 8er -10 dry cylinders. Two such sections are shown in Figure 4. Each section is independently

Condensate is a significant source of feedwater for steam generation, so good water quality is important. In paper mills, oxygen ingress presents a common yet particularly difficult corrosion problem, resulting in unacceptable condensate quality. In many paper mills, oxygen ingress can occur in paper machines operating under a vacuum or during machine downtime. Uncontrolled, the problem …
