Inspection Services

Cement Kiln Inspection Services

Fosbel has the expertise and equipment to undertake a wide range of services for furnace inspection of typically hard to see areas. With each inspection, real-time observations allow the user to focus on any area of interest while capturing all the data on video or still images. The reports provide valuable information on the state of a furnace at a given point of time, and allow for easy comparison with subsequent images.


Fosbel's Lancescope™ system provides real-time, close-up or wide angle views of virtually any area of a furnace or rotary kiln. The system uses a state-of-the-art digital camera system which provides clear, detailed images of problem areas up to 3000°F (1650°C). The system can be inserted into openings as small as 2.75" (7 cm), and reach up to 35 ft (10.7 m). In cooler applications the system provides illumination via fiber optic light source for superb clarity. Successful Ceramic Welding repairs are possible in the transition zone of the oven chamber using the LancescopeTM for "up close" vision of the repair area.

Infrared Thermography

Fosbel employs state-of-the-art infrared technology to inspect furnaces from their exterior to identify potential problems before they become critical. Results can be seen instantly, and a documented report provides a baseline for measuring rates of change.
