Description

一种玻璃池窑及玻璃熔制的方法
本申请要求在2016年06月22日提交中国专利局、申请号为201610474169.X、发明名称为“一种玻璃池窑及玻璃熔制的方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及玻璃池窑技术，尤其涉及一种玻璃池窑及玻璃熔制的方法。
背景技术

玻璃的熔制就是将进入窑炉内的玻璃配合料通过燃烧器加热至高温，使它形成均匀并且气泡、条纹和结石都控制在一定范围内符合成型要求的玻璃液。同时在池底布置的电极通电后电流通过玻璃液产生焦耳热对池底玻璃液进行辅助加热，经过双重加热后的玻璃液通过流液洞进入通路漏板进行拉丝成型。
这种玻璃池窑结构的燃烧器是安装在熔化部两侧胸墙上的，燃烧器的火焰与熔化部玻璃配合料或玻璃液液面平行，主要依靠辐射传热来加热玻璃原料或玻璃液，热利用率低，导致火焰辐射到玻璃原料或玻璃液面上的热量没有得到最佳的利用导致能耗大。如何提高燃烧器的热利用率和稳定度以及玻璃液面的热接受效果是需要解决的技术问题。
