GEA Glashütte Freital ordered GEA for supply and installation of a compact plant for the cleaning of flue gases resulting from melting furnaces. Customer has selected GEA’s BisCat technology (Bischoff Catalysator technology) thanks to low space requirement and combination of several process steps in one reactor. The new furnace has a melting capacity about of 150 t/d, commissioning along with GEA’s emission control plant is foreseen for March 2019.

Generally the furnaces in the glass production 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 to 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 fibers, so-called ceramic candle. These candles are well-proven and very flexible to use even with regard to modifications of operating parameters, especially at high gas temperatures. Even stricter 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 of this kind for the purpose of hot gas filtration and has now refined these plants recently in order 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. 

GEA is represented with a booth at glasstec 2018 from October 23 to 26 at the Düsseldorf trade fair. Visit us in hall 14, booth F49.
