A smooth and stable kiln operation is a condition, where only very small adjustments have to be made to the kiln system. Smooth operation is a prerequisite for a constant and uniform clinker quality. Running a kiln in a smooth and stable manner prolongs the lifetime of the refractory as it enhances the stability of the coating in the burning zone.
Quite a few wet process kilns are still in operation, usually now with higher-tech bits bolted on. However, new cement kilns are of the 'dry process' type. Dry process kilns.
