Why ZSI ?
High and increasing amount of secoundary and/or alternative fuel!
─ High and increasing amount of secoundary and/or alternative fuel creates high chemical load (e.g. chlorids, alkalis). It needs refractory which is Resistance against various chemical attacks
─ High and increasing amount of secoundary and/or alternative fuel creates H2O containing atmospheres. Chemical reaction between H2O and SiC create passive increasing volume.
Passive oxidation of SIC
SiC (s) + 2 H2O (g) -> SiO2 (s) + CH4 (g) [passive], increasing of volume
It needs refractory which is Lower SIC contents, SIC protection“
─ High and increasing amount of secoundary and/or alternative fuel creates more unwanted deposits and build up. Use of various cleaning methods (e.g.: water- and air-canons, Cardox).
It needs refractory which are Mechanical resistance, Abrasion resistance & Thermomechanical resistance
Necessity of a chemical, mechanical and thermomechnical resistant material
Extreme good resistance against alkali attack, also in H2O containing atmosphere
Extreme good resistance against alkali attack, also in H2O containing atmosphere
