等离子点火在褐煤锅炉的试验研究

Experimental Study of Plasma Ignition in Brown Coal Boiler

采用等离子点火技术,煤质越容易点燃,节油率越高。文中结合等离子点火装置在某600MW褐煤锅炉点火初期投运效果不理想,造成锅炉尾部积存大量未燃尽煤粉,发生二次尾部烟道再燃烧事故,威胁锅炉设备的运行安全。通过试验研究,得到了等离子装置应用在褐煤锅炉上的参数特性,为等离子应用在高水分褐煤上摸索出了宝贵的经验。

By plasma ignition technology,the more easily ignited coal,the more fuel-efficient rate.In this paper,according to the plasma ignition device of ignition in a 600MW Brown coal boiler,operation early is not satisfactory,resulting in accumulation of a large number of boilers unburned coal tail,and then causing the secondary accidents,threatening the safe operation of boiler equipment.Through experimental research,plasma device parameters of characteristics of brown coal boiler are obtained to work out valuable experience for plasma applications in high-moisture lignite.
