“…Simulation and energy system optimization models can realize the accurate monitoring of key variables and reduce the energy consumption of the drying process. Many publications have been devoted to the modeling of processes occurring in the drying section of a paper machine [18][19][20][21][22][23]. Mobarakeh et al [24] developed a model to analyze energy consumption (heat and electricity) and CO 2 emission in the main processes involved in paper production.…”

The article presents studies on the impact of the significant process parameters of a paper machine with a Yankee cylinder on its production capacity and heat energy consumption for drying the paper web. Parameters such as machine speed, web moisture content before and after pressing, parameters of steam supplied to the cylinder and parameters of hot air flowing from the nozzles of the hood were analyzed. The study’s results were used to optimize production to improve the energy efficiency and performance of the machine. In order to use the possible methods of improving the production capacity and heat energy consumption, the parameters of the production process were measured and the basic indicators characterizing the operation of the machine were calculated in the Yankee cylinder–dryer hood system. The correct functioning of the machine components and the possibility of their modernization were also analyzed. Technological and construction changes introduced based on the research results made it possible to increase the production capacity by 10% and to reduce the consumption of heat energy per 1 ton of produced paper by 16.3%. The article presents a description of changes in the technology of paper production and modernization of the tissue machine made in the years 2013–2022.

In this study, the heat and mass transfers in the fabric drying process of a single-cylinder dryer are numerically examined in detail by using MATLAB codes and illustrating 3D velocity and temperature profiles obtained by a CFD-ACE+ software package. Seven different drying materials including Polyethylene terephthalate (PET), Polyethylene, Polypropylene, Cotton, Wool, Rayon, and Nylon are employed as drying materials. Influences of the drying-material thickness, contacting percentage, cylinder temperature, feeding velocity, and cylinder diameter are examined in detail. For all cases in this study, it is found that the maximum temperature of the drying material in the drying process is strongly dependent on the thermal diffusivity of the drying material. The higher the thermal diffusivity of the drying material, the greater the peak temperature achieved. The peak temperature of the drying material increases with the increase in the contacting percentage. The higher feeding velocity leads to a faster increase in the temperature of the drying material; however, the peak temperature of the slower feeding velocity is higher than that of the faster one. The heat transfer between the central layer of the drying material and to ambient environment is limited by the thermal diffusivity of the drying material.
