结合华能上海石洞口二电厂600 MW超临界锅炉炉底灰坑频繁堆渣排放的实际情况,利用水下声纳成像技术,开发了高分辨率声纳成像实时监视系统。该系统能实时绘图显示炉底灰坑内灰渣分布情况,使运行人员充分掌握炉底出灰系统的运行情况,取得了很好的效果。 Combining with the actual situation of frequent ash discharge in the ash bottom of a 600 MW supercritical boiler at Huaneng Shanghai Shidongkou No.2 Power Plant, a real-time monitoring system of high-resolution sonar imaging was developed using underwater sonar imaging. The system can plot the distribution of ash in the ash pits at the bottom of the furnace in real time and make the operators fully grasp the operation of the ash discharging system at the bottom of the furnace and achieved good results.
