Abstract
This paper presents several material problems experienced with rotary lime kiln operation, along with approaches to mitigate them Some of the problems discussed are fatigue, high temperature sulfidic corrosion, creep and impact damage, and their effects on burner nozzles, shell, and lump breakers. The information is based upon field experiences during scheduled and non-scheduled maintenance operations in several North American paper mills.
