Application of intelligent identification system for slagging of thermal power boiler

详情

目前，火电厂普遍采用传统的火焰电视来观察炉膛内的结渣情况。由于炉内热辐射大，粉尘和烟气大，只能看到炉内的火焰燃烧，完全看不到清水冷壁或过热器。这些位置的夹渣无法判断。因此，目前开发的火电锅炉智能结渣识别系统采用创新的多光谱技术，可以穿透炉膛内的烟气和粉尘，观察火焰电视无法观察到的水冷壁和过热器的结渣情况。那么如何观察锅炉内部的结渣情况呢？下面说说火电锅炉结渣智能识别系统的使用。
 
At present, there are two kinds of boiler slagging intelligent identification systems. One is mobile detection. Each boiler is equipped with a set of double angle boiler slagging observation instrument in full temperature zone, which is detected through the observation holes at different positions of the boiler. The observation lens at the front end of the equipment can be adjusted according to the observation angle. As an online monitoring equipment, it can become a portable equipment through convenient quick disassembly, Observe other areas in the furnace to play the greatest role; The other is fixed detection, which fixes the equipment at a key observation hole of the boiler to monitor and detect the situation in the furnace in real time. For example, it is fixed on the furnace wall through the transmission mechanism, the front wall of the platen superheater is installed, the image signal is transmitted to the centralized control room, and the slagging in the furnace is observed regularly.
 
When these two kinds of equipment are used on site, it is necessary to extend the equipment into the furnace through the observation hole with the help of the observation holes at various positions of the boiler (the hole diameter must be greater than *0mm). At the same time, the site needs to be connected with compressed air for cooling (the pressure must be greater than 4kg), and then connected with **0V power. Later, lithium batteries will be added to the equipment to facilitate observation.
 
观察相机手动旋转外部仪器，调整相机深入炉膛的观察方向。侧视图不需要旋转**0度，因为摄像机与水冷壁成一定角度进入炉膛。根据需要手动旋转可以看到所有方向。观测距离为6M，观测半径为3M。
 
使用锅炉排渣智能识别系统，可以有效地减少排渣锅炉的威胁，定位和定量识别灰，结焦情况，提供优化的吹灰和焦炭拆除的决定，有效地节约成本，提高锅炉效率。
