摘　　要：介绍了交流等离子点火燃烧器在660MW直流锅炉上的应用情况,阐述了交流等离子点火燃烧器的工作原理,并以实例结合试验研究,讨论了煤粉质量分数、一次风量、二次配风方式对锅炉启动时的点火过程和火焰稳定性的影响,得到了交流等离子点火燃烧器运行的最佳煤粉质量分数、一次风量、二次配风方式,可以用于指导交流等离子点火燃烧器的实际运行。The application of AC plasma ignition burner in 660 MW once-through boilers is introduced, while the working principal elaborated. In combination with experiments and researches, the influence of mass fraction of coal powder, primary air flow, and secondary air distribution mode on the ignition process and flame stability during boiler startup is discussed with actual examples. Optimal mass fraction of coal powder, primary air flow, and secondary air distribution mode are finally obtained, which may serve as a reference for actual operation of AC plasma ignition burners.
