摘　　要：目前,新型高水分褐煤等离子体点火技术在某入炉原煤全水分Mt≥35%的300 MW等级褐煤机组锅炉上成功实现等离子体无油点火。本文通过工程应用试验,采用单因素变量和敏感性分析方法,探究了一次风量、煤量及等离子体发生器功率3个关键参数对燃烧器点火性能的影响。根据试验结果,各关键参数的影响次序为煤量、一次风量、等离子体发生器功率。该结果对于研究新型褐煤燃烧器的点火性能,进行燃烧器设计优化具有重要的指导意义。At present,a new high-moisture lignite plasma ignition technology has successfully achieved oilfree plasma ignition in a 300 MW lignite boiler with the total moisture Mt of raw coal≥35%.This paper de⁃scribes the effect of three key parameters(i.e.primary air volume,coal quantity and plasma generator out⁃put)on the ignition performance of the burner ignition performance through engineering application test and by using single factor variable analysis and sensitivity analysis.The test result shows that the coal quantity has the greatest impact on the ignition performance,and the plasma generator output has the least impact.This conclusion herein has great significance to the design and optimization of burner.
