600MW褐煤机组锅炉设计特点及运行分析

Design Characteristic and Operation Analysis of 600 MW Lignite Coal Boilers

结合褐煤的煤质特性,从锅炉结构、制粉系统干燥出力、磨煤机选型方面,给出了大容量褐煤锅炉区别于常规烟煤锅炉的设计特点,分析了某600 MW等级褐煤锅炉的着火、燃烧、变负荷及结渣特性,表明褐煤锅炉具有良好的发展前景。

Combining with the lignite coal properties, from the boiler structure, the drying capacity of milling system, such as mill selection, this paper presents the design features of large capacity lignite coal boiler different from con- ventional bituminous coal boiler, and analyzed the ignition, combustion, varying load and slagging characteristics of a 600 MW lignite coal boiler. It showed that lignite coal boiler have good prospects for development.
