摘　　要：火力发电中,煤炭燃烧所产生的SO2和NOx会造成严重的大气污染。某电厂2×150 t/h水煤浆锅炉烟气脱硫项目依据石灰石-石膏湿法脱硫技术,基于NT6000分散控制系统对脱硫控制系统进行硬件选型与设计,人机交互界面的设计与绘制和典型生产过程的程序设计与逻辑组态,实现对锅炉烟气的处理。分散控制系统在脱硫工程的成功应用,实现了现场运行状态的远程监测与就地设备的远方及自动控制,既减轻了人工劳动,又提高了生产效率及生产安全性。In thermal power generation,SO2 and NOx produced by coal combustion will cause serious air pollution.The flue gas desulfurization project of a 2×150 t/h coal-water slurry boiler in a power plant is based on limestone-gypsum wet desulfurization technology.Based on NT6000 distributed control system,the hardware selection and design of desulfurization control system,the design and drawing of man-machine interaction interface,and the program design and logic configuration of typical production process are carried out to realize the treatment of boiler flue gas.The successful application of decentralized control system in desulfurization project has realized the remote monitoring of field operation state and the remote and automatic control of local equipment.
