- ItemEvaporation of fluorine, chlorine and selenium from glass melts and emission reducing measures(Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1997) Kirchner, UlrichThe simultaneous waste gas treatment of inorganic gaseous fluorine and chlorine Compounds as well as of gaseous selenium Compounds is still a big problem for many companies of the German glass industry. With the aid of an HVG/AiF research project investigations were carried out with the aim of characterizing the evaporation behaviour of fluorine, chlorine and selenium from industrially melted soda-lime-silica glasses (container glasses) and of correlating their behaviour with the operating data of the melting furnaces. The main effort, however, was put into investigating the absorption rates on an existing waste gas treatment plant depending on the kind and the quantity of the absorption agent. Moreover, the influence of the absorption temperature on the absorption rates was determined.
- ItemSO₂ emissions and sulphur balances of soda lime glass melting furnaces : Report of the International Commission on Glass (ICG) Technical Committee 13 "Environment"(Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1999) Beerkens, Ruud G.C.; van Limpt, Hans; Kirchner, Ulrich; Scalet, Bianca Maria; Kasper, Andreas; van Marcke, Guy; Tackels, Guy; Delhôpital, George; Masy, CharlotteDifferent analytieal techniques for the determination of sulphur balances of glass furnaces have been compared by the Technical Commission 13 (TC 13 "Environment") of the International Commission on Glass (ICG). The calculation of sulphur balances are demonstrated for float glass and Container glass furnaces. The results show the importance of accurate chemical analysis and mass flow measurements for cullet, glass, raw materials and filter dust to predict the sulphur oxide emissions. For float glass furnaces with and without air pollution control and filter dust recycling, the measured sulphur balances show that the difference in calculated sulphur input and sulphur Output of the glass furnace plus air pollution control System can be limited to 5 %. For Container glass furnaces the fluctuations in cullet fraction and cullet quality and instabilities in the melting process (foaming) may cause larger differences in measured sulphur balances: deviaüons in the ränge of 5 to 15 % have been determined. In case of a requirement for very low SO2 emissions, the filter dust recycling for a fuel oil fired furnace is limited according to the sulphur balance and consequently the filter residue has to be partly disposed.
