摘要：

Aggressive fluxes or gaseous species, that slip through flue gas filters, complicate the process control and maintenance of the complex filters behind industrial glass melting tanks. Partly due to a lack of accurate thermodynamic data and kinetic analyses of condensation phenomena, the process control is often based on experience. The two projects presented in this paper focus on condensation phenomena in Na-O-H-S and Na-C-H-B containing flue gases It can he shown that the important phases in sulfur containing flue gas are Na2SO4, NA(2)S(2)O(7) and NaHSO4. Aggressive fluxes form at low water partial pressures between 400 degrees C and 250 degrees C. In boron containing flue gas, the most important species are NaBO2, condensing between 320 degrees C and 160 degrees C, and H3BO3, condensing at temperatures lower than 90 degrees C. The kinetic experiments can be supported by thermodynamic calculations made with the help of Factsage (R).
