摘　　要：以亚临界和超(超)临界发电技术、循环流化床发电技术、整体煤气化联合循环发电技术为研究对象,对不同类型发电机组经济运行数据、废弃物排放等进行了对比分析。结果表明,亚临界、超(超)临界机组烟气脱硫技术成熟,采用低NOx燃烧器及空气分级燃烧技术,可有效降低NOx排放;循环流化床机组污染物控制成本较低;煤气化联合循环机组污染物排放水平很低,并可实现CO2的分离与捕集。Taking ultra-supercritical power generation technology,CFB power generation technology,and integrated gassification combined cycle（IGCC） power generation technology as objects of study,the data in economic operation and in emission of rejected wastages of different kinds of power generation technologies have been analysed.Results of study show that the flue gas desulphurization technology of sub-critical and ultra-supercritical units has matured,by adopting low NOx burners and air-staging combustion technology,the emission of NOx can be effectively decreased;the control cost of pollutant emission from CFB units is lower;the pollutant emission of IGCC units is very low,and can realize CO2 separation and capture.
