Environmental Impact For Regenerators Materials Selection In Soda-Lime Flat Glass Furnaces

The function of regenerators is to use the thermal energy of the waste gases to preheat the combustion air and thereby provide better heat transfer via a high flame temperature. Satisfactory furnace operation can only be achieved if the greater chambers are in good condition. Today, environment issues play a major role in the selection of regenerators and checkers refractories. The impact on the environment has been studied on 35 side-fired flat glass furnaces. Firstly, we will describe in this paper the issues raised by increased carry over CO2 content observed in various furnaces with different types of checker packing such as basket weaves, box, blocks and cruciform's.
