Reduction Of Gaseous Boron Compounds In The Waste Gas Glass Melting Furnaces

For Boron containing glasses, you have to consider a gaseous fraction in the exhaust gas besides the particulate boron compounds. Within the framework of a research project finished in the year 2005 investigations into the emission of a particulate and gaseous boron compounds were carried out on 18 glass melting furnaces with boron containing batch. The plants are different with regard to the molten glasses, furnace type, type of firing as well as downstream emission control technologies. The precipitation of particulate boron compounds is unproblematic. The precipitation of gaseous boron compounds is clearly more difficult and further measures have to be taken in respect of the effective precipitation.
