The level of concentration of sulfur oxides (SOX) in the exhaust gases from glass furnaces is determined by the sulfur content of the fuel and the sulfite/sulfate/sulfide content of the raw materials, especially the incorporation of sodium or calcium sulfate for glass oxidation. The fining chemical Na2SO4, which is applied to batches of silicate glass, has been identified as a source of SOx and a contributory emission. The interaction of Na2SO4 with carbon determines how it decomposes in batches of silicate glass. For the breakdown experiments with Na2SO4 and Na2SO4 + C, inert and O2-rich atmospheres are utilized. Na2SO4 alone has been demonstrated to decompose at roughly 1100°C. Carbon promotes decomposition at lower temperatures due to the presence of lower-temperature breakdown zones at 500°C in O2 and 850°C in N2. SOx are released in 02 at temperatures as low as 500°C. SO(g) and SO2(g) are byproducts of 02 decomposition. SO2(g) is the sole breakdown product of N2. The SO(g) concentration for Na2SO4 + C in O2 at 500 °C is 230 ppmV, and the SO/SO2 peak ratio is 1.23.

reaction that results in the creation of SOx by rearranging active S-O complexes on the melt surface of Na2SO4 can be employed. throughout isothermal decomposition at 1200 °C. Na2SO4 + C in N2 exhibits considerable mass loss throughout the heating-up phase and a zone of higher decomposition rate at shorter periods. Over extended periods of time, the rate of decomposition is equivalent to that of Na2SO4.
