GEA supports the perfect view of exhaust gas treatment in the glass industry

Over the last years, glass demand has grown more quickly than GDP and is still growing. About 0.5 – 0.8 EJ of energy is used for glass production worldwide, and the energy used in the production of container and flat glass results in emission about 50-60 Mt CO2 per year. Improving energy efficiency is one of the most important steps toward achieving three goals of energy and environmental policy: security of supply, economic growth and environmental protection. While adopting GEA emission control technology, energy efficiency of the sector can be improved and governmental regulations of air pollution control be met.

Clean air for the glass industry

Glass industry application

Glass is produced by melting raw materials (mainly silica sand, soda ash and limestone), and often cullet (recycled container glass or waste glass from manufacturing) in glass furnaces of different sizes employing different technologies. GEA is offering a wide range of technologies for the process glass industry. In the glass furnace sector, we mainly provide the following technologies:

 Kilns/Mills

  • Evaporation coolers with Pulse-Jet filters or electrostatic precipitators

 Clinker Coolers

  • Electrostatic precipitators or air/air coolers with fabric filters

 Other

  • SO2 scrubbers, SCR-DeNOxElectrostatic precipitators or fabric filters for coal and cement mills as well as dryers
  • Waste heat recovery / boiler
