Castable or monolithic linings made of fireclay with silicon carbide can offer significant benefits when used in certain, particularly-challenging parts of the cement plant pyroprocessing system. The harsh environment causes a faster rate of anchor embrittlement, alkali corrosion and build-ups. Teplotechna outlines the benefits. By Teplotechna DIS, Czech Republic.
Monolithic linings can provide benefits when used in the inlet chamber, riser duct and lower part of the calciner. In these parts, the presence of alkalis can be high due to the combustion of alternative fuels and therefore can place significant stress on equipment. Depending on the location of the alternative fuel feed, temperatures range from 900-1100˚C.
