摘　　要：华电潍坊发电有限公司3号锅炉是国内第一台燃用贫煤,采用四角切圆直流燃烧器的670 WM超临界机组锅炉。该炉利用美国阿尔斯通公司的技术,采用简单疏水式的启动系统、煤粉浓淡分离、低NOx同轴燃烧系统,具有很好的不投油低负荷稳燃能力和锅炉燃烧效率,在降低炉膛出口烟温偏差方面具有独特的调节手段和效果。重点介绍锅炉冷态动力场试验、蒸汽稳压吹管、制粉系统调试、燃烧特性等试运的情况,提出设备存在的主要问题和改进建议。The No.3 boiler of this power corporation, is the first one in China, which using tangential direct firing system for 670WM units. Using ALSTOM technology, and adopt Simpleness drain type star-up system, Enricher-Pulverized Coal Concentrator and Low Nox Concentric Firing System （LNCFS）, it has low load without oil support, efficient combustion, lower furnace temperature and uniform distribution at any load. The article emphases furnace cold dynamical test, the steady pressure pipe blowing, test of pulvirizer, characteristics of firing and the loading situation, and points out problem with the equipments and give some suggestion.
