RESEARCH OF THE COMPOSITION OF EXHAUST GASES OF GLASS-MELTING FURNACES

The study results of the composition of exhaust gases of fuel- consuming glass-melting furnaces in the production of various glass products are presented. The main provisions of the methodology for determining the content of oxygen, carbon monoxide and dioxide, sulfur oxides, the total value of the nitrogen oxides NOx concentration, as well as the quantitative and qualitative composition of dust in the exhaust gases of furnaces are stated. For the research, traditional techniques were used, adapted to specific conditions. The studies were carried out on an experimental heat recovery stand and during commissioning tests of heat recovery units at various glass enterprises. In addition to our own research results, the work presents data on the composition of exhaust gases obtained from literature sources. Analysis of the content of exhaust gases indicates a fairly wide range of changes in both their qualitative and quantitative composition, as well as the presence of harmful substances in them. In particular, emissions of sulfur compounds into the environment are 100 - 1150 mg/m3, and nitrogen emissions - 1000-4000 mg/m3. Dust content of bake gases fluctuates mainly in the range of 200-300 mg/m3, but can reach 1000 mg/m3.
