Future energy-efficient and low-emissions glass melting processes
conference paper
All over the world, there is an increasing drive to develop new technologies or concepts for industrial glass melting furnaces, with the main aim to increase the energy efficiency, tabilize production and reduce emissions. The application of new process sensors, improved furnace design, intelligent control strategy and waste gas heat recovery systems support the glass manufacturers to achieve ever increasing requirements concerning energy efficiency and emission limits. Glass industries are searching for breakthrough innovations (revolution), but introduction of such major changes in industry is hampered by large risks and investments. Therefore most companies prefer a stepwise improvement (evolution) based on existing concepts, such a regenerative glass furnaces. When different technologies are combined, it will even be possible, in specific cases, to avoid the use of flue gas scrubbers or DeNOx systems. An overview of requirements for industrial glass furnaces is given concerning melting characteristics and performance of the furnaces. A short overview of evolutionary and revolutionary developments in industrial glass melting processes will be presented. In this paper, an example of an optimized, regenerative end-port fired glass furnace concept, based on a combination of current (BAT) technologies, will be given in more detail. Basic innovative elements of such a furnace will be shown and its expected performance.
