摘要
全氧燃烧技术是在玻璃熔制过程中用纯氧代替空气作为助燃气体,与燃料进行燃烧的一种高效强化燃烧技术。在玻璃制造过程中使用全氧燃烧技术可以达到有效地实现节能降耗、减少排放的目的。全氧燃烧技术在玻璃熔窑中的应用,使得其火焰空间的燃烧产物发生了显著的变化。烟气中水蒸气与二氧化碳的含量占到烟气总量的95%以上。在这种条件下,溶解到玻璃液中的水分将会有所增加。该文概述了在全氧燃烧条件下,对玻璃中水分变化进行研究的重要性,并针对水分在玻璃熔体中的溶解机理、存在形式,以及水分对玻璃澄清、玻璃质量所产生的影响进行了综述。
The oxy-fuel firing technology used in glass furnace is a very high efficency combustion technology that in the process of glass melting air is taken place by pure oxygen to improve fuel burning. Adopting the new technology, the main benefits of reducing emissions and saving fuel can be achieved. And according to the technology, significant changs of combustion products in flame space are observed. The content of water vapor and carbon dioxide take up more than 95 percent in the mass particulate emissions. As a result, the water content dissovled in the glassmelt will increase. In this paper, the importance of the research on the changes of water was elucidated, the dissolved mechanism and the water in the form of hydroxyls in glassmeh, as well as the effects of water on the glass fining, glass quality were reviewed.
