CERAMIC MATERIALS SELECTION FOR A GLASS FURNACE RECUPERATOR

Procedures, materials, and results are reported for the materials selection process performed in conjunction with efforts to develop, test, and evaluate high-temperature range recuperator designs for an industrial glass furnace. Material properties, fabrication capability, and relative performance of potential materials in the flue environment of a day tank glass furnace were evaluated. Polycrystalline alumina, reaction sintered and chemically vapor deposited silicon carbides, and sintered alpha silicon carbide proved most satisfactory in the material temperature range of 2300-2800 degrees F. Relatively pure alumina, mullite, and cordierite were most satisfactory at a range of 1700-2300 degrees F. Thermomechanical stress for each material was calculated under expected operating conditions for the optimized design. Material strengths were greater than calculated stresses by factors varying from 2.6 for reaction sintered silicon carbide to 16 for cordierite. Recuperator test sections were subjected to twice the expected thermal stress conditions, with no evidence of failure. A test section was also subjected to the thermal shock of instant transfer between room temperature and a 2000-degree furnace without damage. Results demonstrate the economic fabrication of complex parts made of high-temperature ceramics.
