GlassTrend Seminar 2017
Fives participates at the GlassTrend Seminar on Emission from glass furnaces, April 25, 2017 - 11:40, Haarlem, in The Netherlands.
Meet Fives experts, Andy Reynolds and Wolf Kuhn, who will present the paper below:
"Melting tank heating with electrical, oxy- or aero- combustion power in the light of CO2 emission: an update of input data"
The climate protection imposes more and more stringent limitations on CO2 emissions. Currently, glass melting tanks based on combustion heating reach lowest CO2 emissions of 200 kg/t of glass. In function of raw materials and cullet fraction, up to 200kg/t of CO2 from the carbonates has to be added on to the combustion emissions. This presents a considerable amount of greenhouse gas emitted for the production of glass. The glass industry enquires continuously on means to reduce these emissions in future. Gas firing presents currently the best choice in combustion heating but still produces a significant amount of CO2. Alternatives to reduce further the combustion related CO2 emissions will be reviewed including reflecting on some available innovative technologies for increasing combustion efficiencies. Electric melting ultimately has to provide the best possibilities for the future, although current comparisons rely much on the CO2 produced for electrical generation, the progressive move towards renewable power sources will at some point favour use of electricity at the point of melting. The current situation and future evolution of the CO2 equivalent of grid electricity will be reviewed.
