The paper deals with modeling of steady state and transient thermal processes in a small resistance electric furnace for melting and heat treatment of high quality glass products. The device is designed to obtain molten glass, which can meet the multiple requirements for handling glass and is used for producing of artistic glass sculptures. The temperature field distribution has been studied by 3D FEM modeling of heating and cooling processes under variable conditions specified, depending on the supply power, technological limitations and users’ requirements. Experimental studies have been also carried out in order to verify numerical modeling. The obtained results are reliable basis for optimal control, high efficiency and ensuring of required glass quality.

This paper covers the experiences of the authors based on the studies and developments made within the company over the years, where improvements on furnace design have always been a major issue. Developments have been achieved by driving forces like requirements for higher glass quality, different products, and increased number of product changes, energy efficiencies, lower investment cost and environmental challenges. Although in the glass world today there are studies and projects to develop different radical melting techniques, like plasma melting, submerged combustion, segmented melter and vacuum refiners being the most promising among the many, the progress going from pilot to full scale is slow and not all the glass manufacturers are giving enough funds to support these projects. Even though the conventional furnace technology is quite mature and energy performances of the most energy efficient furnaces [1] and pull rates are approaching near to the limits, there are still differences between the energy consumptions, pull rates and life of furnaces in glass industry today. Many small steps can be taken at different areas like optimizing furnace design criteria, refractory selection, use of additional equipments, and development of sensors, better combustion equipment, advanced control systems. These all add to continuous incremental developments for each project and give us opportunity to progress with feedback from onsite applications.

Glass-melting furnace is the most essential equipment in float glass manufacturing, which greatly affects the glass quality and energy efficiency. A three-dimensional simulation model of a float glass-melting furnace including combustion chamber and glass tank is performed in this paper by CFD software Ansys Fluent. To evaluate the glass quality with obtained simulation output data, a new fining index is proposed from the view of bubble elimination in fining zone of the glass tank. The fining index is verified effective in this paper by comparisons between simulation results and actual industry data. The simulation model and fining index then provide guidance for operating parameters optimization and glass quality improvement.

In this paper we propose the design of a novel induction furnace for glass melting. The design is based on a mathematical analysis and performed numerically by means of the Finite Element Method. Several induction coils configurations were tested. The results from the mathematical model show that it is possible to melt glass in a furnace whose hearth is no larger than half a metre by using axial induction coils and high frequencies. This furnace configuration may result in increased glass melting rates along with the elimination of harmful emissions.
