Furnace camera in a cement kiln

Sensors & Transducers
Durag’s D-VTA 100-20 video and thermography system is specially developed for use in rotary kilns to monitor the clinker manufacturing process. Intelligent sensors allow non-contact, optical and thermal online analysis of processes in the sinter zone in rotary kilns and clinker coolers.
The sensors are specially adapted for the harsh working conditions found in cement processing. The sensor housing contains a special boroscope, the industrial CCD camera and the spectroscopy components. All electronic components are operated outside the kiln area in the cooled camera housing.
A slim 43 mm water-cooled sensor shaft minimises the mechanical stress caused by abrasive dust and the thermal effect on the sensor parts in the combustion chamber. Two optically aligned quartz glass systems are integrated into the boroscope for the emission spectroscopy. The optical system is protected against mechanical and thermal damage by sapphire glass at the sensor tip and is also flushed with air. As no moving parts such as mirrors, prisms or motors are located in the process area, the sensors have a high accessibility with minimum service requirement.
Enhancing main burner operation, the D-VTA 100-20 provides data for secondary fuel control, calculates free lime prediction and allows for stabilisation of product quality. The system also detects snowman and red river conditions, as well as optimising maintenance and repair cycles.
The video system enables a real-time colour video display and visual monitoring of the process sequence in the sinter zone in the kiln outlet/clinker cooler. It provides information on flame form and position; main burner position and condition; clinker formation, consistency, thickness and caking; and ring formation.
For rotary kilns, the D-VTA 100-20 can continuously monitor product temperature and detect hotspots on the refractory lining, thus minimising thermal damage and reducing unscheduled downtime and maintenance costs.
