摘　　要：介绍了神华国能宁夏煤电有限公司鸳鸯湖电厂660 MW机组锅炉的煤质参数与锅炉的燃烧设计,说明等离子喷枪与直流整流电源的技术发展,分析锅炉等离子点火系统的设计性能指标与运行状况,探讨在应用过程中出现的问题,经过系统改造后,从等离子喷枪的运行电压与功率、等离子弧建立时间、直流整流电源的功率因数、输出电流稳流偏差几个方面进行比较,通过具体参数的比较可知,经过改造提升了系统的运行技术指标,达到了改造的目的。This paper introduced the coal quality parameters and of 660 MW unit boiler used in Yuanyanghu Power Plant of Ningxia Coal Power Co. Ltd. of Shenhua National Energy and boiler combustion design, described technological development of plasma spray gun and DC rectifier power supply, analyzed the design of performance index and operation condition of boiler plasma ignition system and expounded some problems emerging in the application process. The reformed system was compared from several aspects of the operating voltage and power of plasma torch, plasma arc setup time, power factor of DC rectifier power supply and steady flow deviation of output current. Through the comparison of specific parameters, running technical indexes of the system are improved and the purpose of reform is achieved after modification.
