“…To study the process of drying perlite by radiation method, an experimental installation was used, shown in Figure 1. This installation allows obtaining sufficient accuracy the results of drying materials by radiation method [10]. The experimental installation consists of scales that can measure the current weight of the perlite test specimens at a resolution of 1 mg. Mass values with a frequency of 3 times per second are sent to the computer with the ability to record them.…”

The actual methods of perlite drying are established. The radiation method of perlite drying is offered. A description of an experimental installation for drying perlite by the radiation method is given. The kinetic regularities of this method are established. Graphical dependences of moisture content on drying time, perlite surface temperature on drying time, and drying speed of perlite on drying time are described. The influence of the initial moisture content of perlite, the value of the heat flux density from the infrared emitter, the thickness of the perlite layer, and the value of the perlite fraction were determined. The analysis on the resulted graphic dependences is made. A drying installation with a combined drying method is proposed. The general conclusions concerning the expediency of a radiation method of drying perlite are made.

“…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.

One of the most energy-intensive processes is the drying process. Therefore, an important task is to reduce heat consumption for drying. Various ways to improve the drying devices of paper and cardboard machines are identified. The main disadvantages of these improvements are given. The limiting factor of heat transfer from water vapor to paper is established. The dependence of thermal resistance on the thickness of the condensate layer is given. The authors have developed a new design for condensate drainage. The developed design allows installing movable siphons without replacement of steam inlet heads of the old type (for fixed siphons) with their insignificant modernization and cutting of an annular groove inside the drying cylinder. This will ensure a minimum level of condensate and eliminate the possibility of suction of steam into the condensate return system. Additionally, this will reduce thermal resistance, heat loss, and reduce energy consumption for paper drying as a whole. Keywords: paper drying, moisture content, drying cylinder, thermal resistance, heat transfer.
