GEA develops BisCat technology for the cleaning of flue gases from glass melting furnaces – Reference at glass kiln Glashütte Freital from 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.
