    This is usually achieved by appropriate provision for radiant heat shielding and cooling air flow. Apart from overheating, the most common cause of seal failure is mate rial loss resulting from stationary and rotating component contact. Since wear between these components is unavoidable, regular inspec tion and opportune maintenance is essential.

  • Kiln Feeding

    The main objective of a kiln feed system is to feed the kiln at any desired rate set by operator (from CCR) and to maintain it with a close degree accuracy (± 2 %) throughout the feed rate range. A fraction (512%) of kiln feed gets lost with preheater exhaust gas. As the chemistry of this dust is normally different from kiln feed composition ...

    Look up the amount of BTU/Hour that your kiln kill give off. You can find the various tables for this here. Use the BTU/Hour figure based on the maximum temperature you will be firing to. You can extrapolate these numbers. For instance you can pick a BTU/Hour number between the column for 2000°F and 2350°F for Cone 6 firing. Assume the maximum temperature you want in the .
