Flue gas analysis in a glass-melting furnace

There would be no glass industry without melting furnaces and burners. For the efficient operation of the plants and the adherence to legally prescribed emission values, the exhaust gas values must be continuously measured and optimised at the furnace, boiler and burner. The most modern emission measuring instruments such as the testo 340 and the testo 350 ensure safe and reliable flue gas analysis in a melting furnace – even at the highest temperatures inside the furnace. This allows you to achieve a resource-saving operation of your plant and guarantees a clear qualitative and competitive advantage.

More efficiency and security in the glass industry

In the glass industry, various different types of furnace as well as continually operated melting pans are used for melting the glass. The melting process leads to chemical reactions of the components melted from the glass raw materials (mixture). The gases O2, CO2, SO2, H2O, NO and NO2 are formed. They are displaced in the refining process in order to prevent the formation of defects on the glass’s surface. The ideal loss value of 15 % should not be exceeded here, as this can hinder the clarification of the glass melt. In order to increase the efficiency of the plant and adhere to the legally prescribed emission limit values for protecting the environment, the gases formed in melting must be measured. The measurements are carried out continuously using stationary instruments and supported and monitored with the help of portable flue gas analyzers. Portable measuring instruments conduct more accurate measurements than stationary instruments.
