DRYER SECTION:

7.1 A comprehensive analysis to determine trouble areas such as syphon clearance, turbulence bars design, steam differential pressure, percent steam blowthrough, velocity in syphon pipes, amount of starch and/or coating pick-up at the size press or

7.2 Calculating the potential capacity of the sections before and after a size press and/or coater.

7.3 Calculating in an elaborate form the following and comparing the results with ideal conditions and industry standards. This is done per total machine, per group or per target cylinder can.

7.3.1 Related Rates (evaporation, condensation and production).

7.3.2 Related Rates/Area (evaporation, condensation and production).

7.3.3 Steam Consumption (per weight of water, per weight of paper and per unit time).

7.3.4 System Blowthrough (percent and weight per unit time).

7.3.5 Energy Consumption (per weight of water, per weight of paper and per unit time).

7.3.6 Water Evaporated.

7.3.7 Sheet Travelling Time.

7.3.8 U-Factor.

7.3.9 Optimization (fabric tension, steam pressure differntial).
