    The paper seeks to make a glass industry recommendation on the preferred method for the measurement of particulate emissions in the waste gases from glass melting tanks. A compilation of work is presented carried out by laboratories in five European countries to compare the commonly used methods. The methods are described briefly with particular reference to the principal differences of filter configuration, materials and situation. The variables have been studied and recommendations are made on the necessity to standardise certain aspects. The methods have been compared by simultaneous measurements on different types of furnaces with different fuels and glass compositions. The principal difference between the methods lies in whether the filter is situated inside, or outside, the stack. It is concluded that in-stack filtration should be preferred since it avoids the errors and uncertainties associated with the condensation of solid and liquid phases in out-of-stack filter systems.

    SO₂ 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, Charlotte
    Different 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.
