German container glassmaker Glashütte Freital has ordered a compact plant for the cleaning of flue gases from melting furnaces.
The glass manufacturer selected GEA’s BisCat technology thanks to its low space requirement and combination of several process steps in one reactor.
“During my working life I was in touch with GEA several times and experienced them as a competent, reliable partner.
So our decision towards GEA was based on trust in both the technology and the company,” said Hans-Bernhard Führ, Glashütte Freital’s General Manager.
The new furnace has a melting capacity of 150 t/d. Commissioning alongside GEA’s emission control plant is expected in March 2019.
Glass production furnaces are equipped with flue gas cleaning plants which have separate steps for treatment of particulate, acid crude gases and nitrogen oxides.
GEA has developed a technology which reduces these steps into one single step in a single reactor.
The flue gas cleaning process is carried out by means of rigid filter elements consisting of coated mineral fibres, so-called ceramic candles.
These candles are proven and flexible to use even with regard to modifications of operating parameters, especially at high gas temperatures.
Future requirements set in the Federal Administration‘s Regulation ‘Technical Instructions on Air Quality Control (TA Luft)’ will be underrun. Dust emissions are near to detection limit.
GEA has already delivered plants for this kind of hot gas filtration and has now refined these plants to include the separation of nitrogen oxides resulting from flue gases (DeNOx).
The ceramic candles are installed in a walk-in clean gas chamber to ensure easy access for maintenance and inspection.
