Modeling and Control of the Paper Machine Drying Section
… is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. The moisture in the paper is controlled by …

Steam and Condensate System Control in Paper Making
The function of a paper machine is to form the paper sheet and remove the water from the sheet. A modern paper machine is divided into three main parts, the wire section, the press section, and the dryer section. Although the dryer section is only responsible for removing less than 1% of the water …

Dryer Section Control in Paper Machines During Web Breaks
Web breaks in the dryer section of a paper machine cause loss of production and quality problems. After a web break, the steam pressure in the cylinders must be reduced to avoid overheating. The goal of this project is to determine optimal steam pressure trajectories during web breaks, so that the …
