Secondary measures for reduction of NOx emission in glass melting process

Abstract

In this paper the new methods for reduction of NOx emission from glass melting furnaces were presented. The secondary measures are focused on development of different methods for elimination of nitrogen oxide from the smoke gasses. The main characteristics of the selective catalytic reduction process (SCR), selective non catalytic reduction process (SNCR) and 3R process were presented and some advantages and limitations of these processes were analyzed.

U ovom radu su prikazani novi postupci smanjenja emisije NOx iz peći za topljenje stakla. Zbog visokih temperatura do kojih se zagreva vazduh neophodan za sagorevanje dolazi do visoke emisije oksida NOx iz staklarskih peći. Sekundarne mere usmerene su na razvoj postupaka za uklanjanje azotnih oksida iz dimnih gasova. Dat je prikaz selektivno nekatalitičkog, selektivno katalitičkog redukcionog i 3R postupka kao i njihove prednosti i nedostaci.
