AI Technical Summary
Existing electric resistance heating systems for glass melting face challenges such as electrode corrosion, material loss, high energy consumption, and limited flexibility in adjusting energy input, leading to poor glass quality and increased carbon footprint.
A method and vessel design using multiple inverter-based heating circuits with adjustable amplitude and phase angle, allowing for overlapping current paths and independent control of power distribution, reducing electrode corrosion and enabling flexible operation without structural changes.
Achieves high electric efficiency, improved glass quality, reduced carbon footprint, and increased flexibility in producing various glass types by optimizing power density and flow profiles without rebuilding the melting vessel.
