Inspection of the refractory lining in a PFR kiln

To ensure smooth kiln operation, the condition of the refractory lining of a kiln should be inspected periodically. For a comprehensive inspection, the kiln still has to be shut down and emptied. Maerz Ofenbau has developed a system to perform a partial inspection on a running kiln, especially in the ring channel, without emptying and cooling the kiln. A special water-cooled camera is used for this purpose.

In mid-June 2023, one of these cameras was successfully used at two locations of our customer Grupo CALIDRA in Mexico.
