The paper machine is finished off with a calendering section and a reel-up, where the paper is reeled on a so-called reeling drum. The paper on the reeling drum is subsequently cut into suitable sizes in a slitter-rewinder and is then ready for delivery. Nearly of the supplied steam is used to dry the pulp to paper.

Optimization of water removal in the press section of a ...

Abstract. An optimization problem regarding water removal in the press section of a paper machine is considered in this work. The proposed model tries to minimize a cost function comprising the replacement of the felts in the press section, the cost of energy to operate the press and the cost of energy in the drying section, while satisfying the constraints of water mass balance in the process.

Exergy Analysis of the Revolving Vane Compressed Air Engine

Exergy analysis was applied to a revolving vane compressed air engine. The engine had a swept volume of 30 cm 3 . At the benchmark conditions, the suction pressure was 8 bar, the discharge pressure was 1 bar, and the operating speed was 3,000 rev·min −1 . It was found that the engine had a second-law efficiency of 29.6% at the benchmark conditions.
