Monolithic Refractories Materials ZSI – Product Series (Refko Refractories)

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
