The document discusses the importance of monitoring the condition of the refractory material in rotary kilns during cement processing. It highlights the development of the CS400 kiln shell imaging system by Fluke Process Instruments, which enables continuous infrared monitoring to detect hot spots and optimize kiln performance. This solution aims to extend the operational life of kilns and prevent costly failures in harsh manufacturing environments.

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.
