Overview of boiler slagging and coking monitoring system

"Boiler slagging and coking monitoring system" is a comprehensive monitoring system that combines multimedia technology, computer technology, digital image processing technology, pattern recognition technology and industrial TV technology. The system uses a high-temperature endoscopic optical imaging probe to monitor the slag discharge shrinkage of the boiler in real time, which can intuitively display the slag discharge conditions in the slag hopper. Focused, the image is clear. It is also equipped with a slag machine surveillance camera to monitor the operation of the slag machine in real time. The endoscopic probe can be remotely controlled to advance and retreat in the centralized control room. In the event of an abnormal situation, the system will automatically control the probe to exit the working position to protect the probe from being damaged. The system uses a new pattern recognition algorithm to process and analyze the surveillance images, which can effectively and reliably determine the coking, automatically alarm when the coking reaches a preset level, and store video and image information as the basis for accident analysis. Compared with the traditional coking alarm, it is more accurate, has stronger predictive ability and lower error rate. The system management adopts a multi-user and multi-level management mode. The entry and exit of the system are protected by passwords, and various operation information and alarm information can be recorded to facilitate the division of responsibilities afterwards.

 

The function of boiler slagging and coking monitoring system

The upper computer control system receives the monitoring images of the four-way slag hopper shrinkage and the two-way slag scavenger at the scene, which can be displayed on the human-computer interaction interface at the same time, and can also switch the display of the four-way slag bucket image and the two-way slag scavenger image. Or single-screen cycle display.

The host computer receives the alarm signal of the on-site control cabinet and displays the alarm signal status of each electric actuator (including the alarm of over temperature, abnormal wind pressure, coking and video loss) with red and green indicator lights in the user operation area.

When a single screen is displayed, the advance, retreat and rotation of the probe can be remotely controlled in the centralized control room through the host computer. The corresponding motion button will be displayed in red when the probe is moved into position. When displaying a single channel, you can also set the parameters of brightness, contrast, chroma and saturation of this channel of image, so that the image can achieve the best observation effect.

This system is multi-user hierarchical management, and users of different levels have different operation rights. To start the system operation or perform various operations in the system, users with corresponding rights can only operate after logging in.

After starting the system, various image capture cards and input and output boards will be turned on, and the system will enter a fully operational state. The interface will display various video images and various alarm signal states, focus judgment, and all video and recording functions will start to run.

If the board has installation problems or hardware failures, the system's self-checking program will give corresponding failure prompts, and you can repair according to the prompts or contact the manufacturer for troubleshooting.
