传统的玻璃熔融方法是空气-燃料燃烧法，效率低、耗能大、耗时长。本研究开发了一种创新的飞行熔融技术，并将其应用于玻璃生产中，以达到节能环保的目的。采用射频（RF）等离子体、12相交流电弧和氧气燃烧器三种热源，研究了颗粒状粉末的飞行熔化行为。结果表明：熔化后的颗粒呈球形，表面光滑，结构致密。熔化后的颗粒直径约为原粉末直径的50%。粉末的分解和玻璃化程度依次为射频等离子体、12相交流电弧和氧气燃烧器制备的粉末。最大的热量传递是从射频等离子体到颗粒，导致最高的颗粒温度（1810℃）和最大的原料玻璃化程度。高分解和玻璃化程度，这是在几毫秒内实现的，大大缩短了玻璃的熔化和细化时间。我们的结果表明，所提出的飞行熔融技术在玻璃工业中是一种很有前途的方法。
Abstract The conventional method used for glass melting is air-fuel firing, which is inefficient, energy-intensive and time-consuming. In this study, an innovative in-flight melting technology was developed and applied to glass production for the purposes of energy conservation and environmental protection. Three types of heating sources, radio-frequency (RF) plasma, a 12-phase alternating current (ac) arc and an oxygen burner, were used to investigate the in-flight melting behavior of granulated powders. Results show that the melted particles are spherical with a smooth surface and compact structure. The diameter of the melted particles is about 50% of that of the original powders. The decomposition and vitrification degrees of the prepared powders decrease in the order of powders prepared by RF plasma, the 12-phase ac arc and the oxygen burner. The largest heat transfer is from RF plasma to particles, which results in the highest particle temperature (1810 °C) and the greatest vitrification degree of the raw material. The high decomposition and vitrification degrees, which are achieved in milliseconds, shorten the melting and fining times of the glass considerably. Our results indicate that the proposed in-flight melting technology is a promising method for use in the glass industry.
