Abstract

Some embodiments of the present disclosure provide electric heating devices and methods for kilns of substrate glass, relating to the field of arrangements of electric heating structures for the kilns of substrate glass. To address the problem of insufficient melting in front zones of kilns of high-generation and large-tonnage substrate glass, a heating structure combining side-stack tin oxide electrode bricks and bottom-inserted molybdenum electrodes is designed. A comprehensive thermal efficiency of the kiln is determined by introducing an appropriate amount of gas and determining an energy consumption of glass melting and a thermal energy contribution of gas and electricity under an extraction volume. This leads to a novel electric heating device for the kiln of high-generation and large-feeding substrate glass and a method thereof, effectively solving the problem of insufficient melting and unstable convection in the front zone of the kiln.
