Possibilities of Reducing the Heat Energy Consumption in a Tissue Paper Machine—Case Study

Abstract

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.

Measurement and Control of Corrugated Board Production Parameters Taking into Account Individual Operator Preferences

“…The development of the discussed system was part of a larger project aimed at introducing process innovation in adhesive preparation and dosing, where a local circulation of adhesive with control of its concentration directly at the glue pans was implemented. The work began with a series of measurements of process variables using portable thermometers and moisture meters [ 27 , 28 , 29 ]. Based on the analysis of temperature and moisture measurements of the raw materials and the product, measurement points were selected for monitoring using a continuous registration system for process variables [ 30 ].…”

Impact of air jet impingement technology on the strength of tissue paper

“…The advantage of this technology is the production of papers characterized by high bulk, softness, and absorbency. Unfortunately, the paper production process using a TAD machine involves higher investment costs and energy consumption (Kullander et al 2012;De Assis et al 2018;Reczulski et al 2023).…”
