HEAT LOSS ASSESSMENT AND REDUCTION METHODS IN GLASS PRODUCTION LINES: THE CASE OF THE “KVARTS” PLANT

Abstract

Glass production is an energy-intensive industrial process in which a significant share of supplied thermal energy is lost at different stages of manufacturing. This study focuses on the assessment of heat losses in glass production lines at the “Kvarts” plant with the aim of identifying the main sources of thermal inefficiency and evaluating their impact on overall energy performance. The research is based on an energy audit of thermal-technological equipment, including glass melting furnaces, auxiliary heating systems, and heat transfer structures. Operational parameters, temperature distributions, and insulation conditions were analyzed to determine the dominant heat loss mechanisms. The results indicate that major heat losses occur through exhaust gases, furnace walls, and outdated thermal insulation, leading to increased fuel consumption and reduced thermal efficiency. Based on the findings, practical methods for reducing heat losses and improving energy efficiency are proposed. The outcomes of this study can be used to optimize energy use, reduce production costs, and support sustainable development in the glass manufacturing industry.
