摘要: 通过对文献进行数据挖掘,归纳因锅炉化学水工况选取不当而造成事故情况,确定了一些常见锅炉机组的最适化学水工况:对于机组功率在0~200MW范围内、主蒸汽压力≤15.7MPa(超高压范围)的汽包锅炉,建议采取平衡磷酸盐处理(equilibrium phosphate treatment,EPT);对于机组功率在200~600MW(不含200MW)范围内的亚临界直流炉,建议采取给水加氧处理(oxygenated treatment,OT);对于机组功率在600~1000MW(不含600MW)范围内的超临界以及超超临界直流炉,建议采取给水加氧处理(OT).

Abstract: Through the method of literature data exploitation,this paper summarized the power plant accident caused by the inappropriate chemical water treatment and also summarized the advised chemical water treatment. After analyzing the data,the most suitable chemical water condition was chosen for the common unit. Firstly,for the drum boilers with a unit range of 0-200MW and main steam pressure below 15.7MPa,the advised condition is equilibrium phosphate treatment(EPT). Secondly,for the subcritical once-through boilers with a unit range of 200-600MW(excluding 200MW),the advised condition is oxygenated treatment(OT). Thirdly,for the supercritical and ultra-supercritical once-through boilers with a unit range of 600-1000MW(excluding 600MW),the advised condition is oxygenated treatment(OT).

Key words: data exploitation, power plant, chemical water condition, drum boiler, equilibrium phosphate treatment(EPT), once-through boilers, oxygenated treatment(OT)
