The molten material cushion at the bottom of the alkali recovery boiler plays a crucial role in the furnace's chemical reaction conditions. Its height and shape are essential for adjusting the black liquid spray gun and primary air. Cushion detection allows operators to monitor its condition from the control room. Given the presence of black liquid drips and alkali and mirabilite dust in the harsh high-temperature environment, this process requires precise monitoring.
The RB-TemTV-M1500 camera system, developed by our company, provides real-time, high-definition images of combustion and ash accumulation within the boiler, helping optimize boiler operation. The system features an optimized optical design and a specially engineered cooling and purge mechanism to prevent ash buildup on the probe while ensuring cooling efficiency. In emergency situations, a retraction device is included for lens protection. The cooling air system is connected to both the relay lens unit and the camera housing.
The IR-Camera for Recovery Boiler includes an automatic retraction device and slag cleaning mechanism. If cooling air is interrupted, an overtemperature condition occurs, or power failure happens, the retraction device automatically withdraws the probe to protect it. Before the lens extends into the boiler, the automatic ash cleaner removes any accumulated ash from the installation hole to prevent it from contacting the lens.
The camera's unique infrared image sensor ensures clear visibility even in hot, dusty environments. It can display temperature readings for multiple areas or points simultaneously.
