摘　　要：介绍了锅炉无油冷态启动的实现过程,分析了等离子点火系统及MPS190中速磨煤机制粉系统在冷态和热态试运过程中出现的问题及处理办法。通过带负荷后的燃烧调整,锅炉在试运期间实现了高效、安全、稳定运行。在整个启动调试期间,实现了无油冷热态启动、吹管、甩负荷、低负荷稳燃和滑停等关键环节,节省了大量燃油,具有良好的经济和社会效益。The implementation procedure of boiler cold start without oil was introduced.The problems of plasma ignition system and MPS190 coal pulverizing system with medium speed mill occurred in cold state and hot state trail running were analyzed,and relevant treatment methods were given.By the combustion adjustment with load,the high-efficient,safe and stable operation of the boiler during trail running period was realized.In whole start-up debugging period,some key links were realized,which included the cold start and hot start without oil,the pipe blowing,the load rejecting,the combustion stabilizing in low load and the shutdown with variable parameters;a great amount of fuel oil was saved;and favorable economic and social benefits were obtained.
