数学模拟在电熔玻璃窑炉中的应用
Experiences with mathematical modeling of electro-boost in glass furnaces
摘要 在最近的公司策略中,玻璃公司的主要目的是降低生产费用的同时保持或提高玻璃的质量。其中一个有效的方法就是在当前窑炉上安装电助熔或建新窑时带电助熔。该策略或许令人感到惊讶,因为通常来说电的价格要远远高于气或油的价格(从每单位能量的单价考虑),但是从能量利用的效率来看(通过焦耳热直接给玻璃加热)它还是比较有效的。本文介绍了CFD模型在电助熔设计当中的应用。GS玻璃窑炉模型(GS-GFM)被用来研究最佳的电极排布和相位调整,以及电助熔使用期间提高玻璃的质量。
Abstract:
The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality.One of the perspective ways is to install the electric boosting into the existing furnace or to build the new furnace including the electric boosting.This strategy may be surprising as electric energy is generally more expensive than gas or oil (considering the cost per unit energy) but because of efficiency of use (direct glass-melt heating by Joulean heat) it is inevitably cost effective.The use of the CFD modeling capability for electro-boost designing is presented in this contribution.The Glass Service Glass Furnace Model (GS-GFM) is used for investigating the optimal electrode arrangement and phasing,and moreover,for increasing the glass quality during the electro-boost applying.
