Service of refractories in the regenerator nozzle glass furnace
https://doi.org/10.17073/1683-4518-2024-5-71-75
Abstract
The exhaust flue gases in glass furnaces include products of gas combustion and charge degassing, as well as products of evaporation from the glass melt. Of the main (CO2, H2O, N2 and O2) and secondary (Na, NaOH, Na2SO4, NaCl, HCl and SO2) smoke components for the service of refractories in the regenerator nozzle, sodium sulfate is the most problematic. The change in the aggregate state of gaseous Na2SO4 during the smoke cooling process gives rise to the release of two zones in the middle part of the nozzle: condensation and crystallization of sodium sulfate. Specifying the temperature intervals within which condensation (1100‒880 °C) and crystallization (880‒725 °C) of sodium sulfate occur allows us to formalize the technical conditions for the design of nozzles for single-turn and multi-turn regenerators of glass furnaces.
