32 Applications

The many applications of CFCCs illustrate the variety of their shapes and sizes (Fig. 3.5). Cylinders or tubes are widely used in industry. They are usually made of metals, either wrought or centrifugally cast. They commonly fail by corrosion from products of combustion, or erosion, or creep when operated at high temperatures, and are relatively heavy. They are subject to fouling, especially when catalyzed by metal-alloyed constituents required for high-temperature use. Ceramics have advantages over metals: higher temperature capability, lighter weight (requiring less support structure), corrosion resistance (permitting reduced wall thickness), and reduced fouling, especially with silicon carbide.
