摘　　要：华电潍坊发电有限公司3号炉是国内第一台燃用贫煤,四角切圆直流燃烧器的670WM超临界机组锅炉。该炉采用美国阿尔斯通公司的技术,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。重点介绍了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,以及设备存在的主要问题和改进建议。The No. 3 boiler of Huadian Weifang power corporation, is the first one in China, which using tangential direct firing system for 670WM unit. It is using ALSTOM technology, adopting 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 highlighted furnace cold dynamical test, the steady pressure pipe blowing, test of pulvirizer, characteristics of firing and the loading situation. Problems with the equipments are pointed out and some suggestion are put forward.
