2×660 MW超超临界锅炉方案选型研究

The Type Selection Research of 2×660 MW Ultra-supercritical Boilers

针对某厂2×660 MW超超临界机组项目可用煤源(包括煤泥、煤矸石和烟煤)情况,对机组锅炉选型问题进行了分析研究。从机组建设成本、运行成本、环保指标等方面,比较了高效煤粉(PC)锅炉和循环流化床(CFB)锅炉优缺点。分析研究表明,该厂采用CFB锅炉具有投资省,运行成本低等综合优势。

According to the coal resource（including slime,gangue,bituminous coal）,type selections of 2×660 MW CFB boilers were discussed. The advantages and disadvantages of high efficiency pulverized coal（PC）and circulating fluidized bed（CFB）boiler were compared in terms of construction cost,operating cost and environmental protection. The analyses showed that the CFB boiler had the advantages of low investment,low running cost and good comprehensive advantages.
