在玻璃工业中,用于玻璃熔化的能耗占整个工业总能耗的30%~75%,根据玻璃品种的不同,能源成本占总成本的10%~25%。因此,提高玻璃熔窑热效率对降低玻璃制造成本有极其重要的影响。能源价格的急剧上升,全球气候变暖和对二氧化碳排放的限制,以及投资成本的增加等都推动了玻璃熔化技术的发展。本文讨论了玻璃熔窑的热效率,并介绍了选择性配料、对配合料和熟料进行预热的全氧燃烧的技术发展。还介绍了一些非传统先进熔化系统的开发,如分段式熔化技术,浸入式燃烧技术,以及通过数学模拟来优化燃料分布达到节能的目的。

Typically, energy efficiency of glass furnaces offers major opportunities for manufacturing cost reduction.Significant rising of energy cost, environmental requirements for clean air and pressure for reducing global warming and carbon dioxide emissions, as well as the cost of capitals are main drivers for the technology developments. In this paper, energy efficiency of glass furnaces is discussed. Technology developments in selective batching, oxy-fuel firing with preheating batch and cullet, non-conventional advanced melting systems, such as segmented glass melting and submerged combustion melting, as well as using math modeling to optimize fuel distribution for energy savings are presented.

玻璃厂的主要目的是在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熔窑上安装电助熔或建新窑时带电助熔。该思路或许令人感到惊讶,因为通常来说电的价格要远远高于气或油的价格(从能量单价考虑),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玻璃熔窑模型(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。

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.
