High emissivity ceramic coatings for refractories, no longer “theoretical” technology, are being used successfully in furnace applications to reduce energy consumption, improve temperature uniformity, reduce maintenance, and increase production while improving product quality. By increasing the emissivity-a materials' ability to absorb and reradiate energy-of a refractory lining in a furnace, these specialized ceramic coatings can provide energy savings depending on the fuel being used, the furnace operation, furnace configuration, and production schedule of at least up to 24%. Furthermore, furnace heatup time is decreased and the service life of the high emissivity ceramically coated refractory is extended. A series of ceramic coatings proving most valuable in thermal processing operations have been developed by H & S Coatings, Pittsburgh, PA.
