Kilnscan

INFRARED ROTARY KILN SCANNER

Kiln Shell Thermal Monitoring

Kilnscan is a high performance thermal kiln scanner dedicated to the real-time, 24/7 temperature monitoring of the kiln shell. It displays the full temperature profile of the kiln and gives early warning of hot spots indicative of refractory failure.

With the highest scan angle of the industry of up to 140°, Kilnscan adapts to any kiln configuration. Therefore, long-shell kilns with limited free space around, kilns with multiple shadows generated by posts, and other variations can be accommodated.

Thanks to advanced features such as the unique thermal warp calculation and historical data management, Kilnscan provides the operator with the full picture of the rotary kiln to secure a predictive maintenance program. 

Kilnscan thermal scanner for kiln shell in operation

Kilnscan infrared scanner contributes to optimizing kiln efficiency and availability, increasing production rate, reducing operating costs, improving the burning process and saving energy.

3 Key Points

Shell scanner with the highest spatial resolution, smaller than the average refractory brick size

Unique Thermal Warp calculation and historical data management

Unique scan angle from 90° up to 140°

KILNSCAN

High performance diagnosis system for continuous temperature monitoring of kiln shell

With the best spatial and thermal resolution, Kilnscan monitors each individual refractory brick over the whole length of the kiln. It tracks hot spots, tyre slip, rings formation, brick failures, thermal warp and more, to prevent short- and long-term damages. Kilnscan is a rugged system designed for demanding environments. With more than 1,300 units operating around the world, HGH thermal scanners are used in plants to warn of potential failures and trigger preventive actions.

Kilnscan Features
