An overview and the recent advancement of combustion applied to glass melting furnaces

Abstract

The glass industry stands at a critical moment in its evolution, confronted with the urgent need for decarbonization while striving to maintain operational efficiency and product quality. This paper delves into the current scenario of the glass industry, highlighting its significant contributions to global sustainability efforts while confronting substantial challenges in reducing carbon emissions. This paper looks at different ways to reduce carbon emissions in glass production, focusing on how much energy is needed to make glass and how important melting furnaces are to this process. These include using oxy-fuel, electricity, hydrogen, and possible combinations. Emphasizing the need for innovative approaches to mitigate refractory corrosion and other operational issues resulting from changes in combustion processes, the study underscores the importance of ongoing research and development in materials science and combustion technology. The paper looks at how the different parts of the furnace, its atmosphere, flame, and the refractory behave in complex ways. This helps us understand how to improve furnace performance and make them last longer so that the glass industry can be more sustainable.
