研究了松散玻璃配合料和颗粒玻璃配合料的物理性能、预反应性能和熔融性能。实验结果表明，压实玻璃混合料可以减少粉尘，使用超细粉末，提高换热效率。将松散玻璃料压成颗粒状后，预反应活化能Ea从178.77 kJ/m o l降低到143.30 k J/m o l，导热系数从0.273 W/m·°C增加到0.430 W/m·o l。使用预反应颗粒玻璃混合料可以显著缩短熔化时间，提高配合料熔化速度，使每公斤熔体玻璃的热耗由3591.24降至3277.03kJ/kg。
The physical properties, the pre-reacting performance and melting properties of the loose glass batch and the granulated glass batch were investigated, respectively. The experimental results showed that compacted glass batch could reduce dust, use ultra-fine powder, and improve heat transfer efficiency. When loose glass batch was compressed into granular, the thermal conductivity was increased from 0.273 W/m·°C to 0.430 W/m·°C, the activation energy Ea of pre-reacting decreased from 178.77 kJ/mol to 143.30 kJ/mol. Using the pre-reacted granular glass batch can significantly reduce the melting time, increase the batch melting rate, and decrease the heat consumption of 1kg molten glass from 3591.24 to 3277.03kJ/kg.
