Summary

Refractory materials must withstand a variety of aggressive agents, hydrogen, steam, sulfur. sodium, and vanadium in most gasifiers. The correlation of desired physical properties and service conditions is reviewed and suggestions are offered on lining designs. Analysis of refractory from slagged area showed degradation and cracking due to a combination of chemical and thermochemical deck. Major alkali and sulfur penetration was observed along with some evidence of vanadium penetration. The use of a less permeable refractory reduced corrosion attack and improved thermochemical performance.
