浮法玻璃熔窑的保温节能

摘要

By studying the heat conduction mechanism of a glass melting furnace in the production process with the thermodynamics principle,an ideal model of the glass melting furnace which ignores some objective condition effects,such as orifice radiations,has been established to calculate the amount of the furnace heat dissipation.The results show that the heat loss to the surroundings due to the poor performance of the outer wall insulation layer is the major cause of the high heat consumption of the existing furnace.The derived theoretical formula make it possible to accurately configure the type,amount and specification of the heat preservation material of the melting furnace for energy saving and heat preservation.The results of a practical application on a glass melting furnace have a good agreement with the calculated ones,verifying the reliability of the theoretical calculation formula.%本文研究了熔窑在生产过程中的传热机理,通过建立一个忽略了孔口辐射等客观条件对熔窑散热量影响的玻璃熔窑理想模型,得到可以量化熔窑散热量的计算方法.研究表明:因熔窑外壁保温层性能欠缺而向周围环境的散热损失是现有熔窑热耗较高的主要因素.运用得到的理论计算公式,可以准确地配置熔窑节能保温所需的保温材料种类、用量及其规格.通过在某玻璃熔窑上实际应用,对计算的结果与实测结果进行对比分析,验证了理论计算公式的正确性.
