Multiple requests from the same IP address are counted as one view. Glass manufacturing is an energy-intensive process in which oxy-fuel combustion can offer advantages over the traditional air-blown approach. Examples include the reduction of NOx and particulate emissions, improved furnace operations and enhanced heat transfer.
Each point refers to one existing container glass furnace. Specific energy data are normalized to 50% cullet and the primary energy consumption takes electricity and oxygen production into account (adapted from Reference [ 6 ]). Oxygen-firing is an effective solution for saving energy in glass furnaces.
The overall energy consumption for an oxy-fuel glass melting furnace is approximately equal to the one in case of air combustion [ 7 ]. Beerkens [ 7] assumed 0.375–0.4 kWh for the electricity consumption per Nm 3 of pure oxygen generation. Based on an electric plant efficiency of 40%, ~3400 kJ Nm −3 are assumed for the primary energy consumption.
The company also continues to look to oxy-fuel furnace technology, which melts glass raw materials mixing pure oxygen (instead of air) with natural gas, significantly improving energy and environmental performance.
