摘　　要：为明确循环流化床烟气脱硫(CFB-FGD)技术在工业过程中的适用性,采用模糊综合评价法建立了烟气脱硫技术(FGD)性能的综合分析平台。该平台综合考虑了经济、环保、技术性能等多方面因素,能够提供科学、直观地分析结果。本文利用该平台对七种常见FGD技术进行了分析,基本综合评价结果表明,工业常用的海水法与石灰石-石膏湿法烟气脱硫技术的表现最佳;条件综合评价结果显示,干法CFB-FGD是缺水地区的首选。To clarify the industrial application potential of circulating fluidized bed-flue gas desulphurization(CFB-FGD),a flue gas desulphurization(FGD) evaluation tool was developed with the fuzzy comprehensive evaluation method.To provide direct and scientific results,the evaluation system considers both qualitative and quantitative factors on technical,economic and environmental aspects.In this study,semi-dry/dry CFB-FGD and other five common FGD methods were analyzed for general and conditional evaluations.Results indicate that seawater and limestone-gypsum wet(LGW)methods give comprehensively better performance under general conditions,while dry CFB-FGD method is suggested for power plants in water deficient areas.
