The document discusses cement processing and how infrared monitoring of kiln shells is critical for cement manufacturing. It explains that monitoring the outer surface of kilns is the only way to determine the condition of the refractory material inside since temperatures cannot be measured directly from within. The Fluke CS400 Kiln Shell Imaging System was developed to help continuously detect hot spots on kiln shells through infrared monitoring to extend the life of kilns and prevent failures.

1. Cement Processing
Cement Processing - Infrared Monitoring of Kiln Shells
For nearly every cement manufacturing process, one of the most
critical steps take place within the rotary kiln. Because of this, it is
imperative that users understand the condition of the refractory
material coating the kiln to extend its operating life, as well as to
prevent any disastrous failures.

2. Since users have no way to measure temperatures from inside of
the kiln, looking at the outer surface is the only way to determine
the refractory condition of the kiln. To aid operators in this task,
Fluke Process Instruments has developed a continuous infrared
process monitoring solution – the CS400 Kiln Shell Imaging
System – which is designed to help users continuously detect hot
spots, reduce set up times, avoid costly damage, optimize the
kiln’s operational life and more, even in the harshest cement
manufacturing environments.
