摘　　要：石灰石/石膏湿法烟气脱硫是目前世界上应用最广泛的烟气脱硫技术,对其进行科学的评价并优选出最适合于我国国情的工艺具有非常重要的意义。建立了燃煤电厂石灰石/石膏湿法烟气脱硫技术综合性能评价的多级模糊数学模型。因素集由环境性能指标、经济性能指标和技术性能指标三大类组成,其中每一个因素集包括了具体的评价指标,引入了3种模糊综合评价方法,并将这3种方法的优点结合起来,对5种石灰石/石膏湿法烟气脱硫技术进行了三级模糊综合评价,通过最大隶属原则得到客观的评价结果。综合评价结果可以指导石灰石/石膏湿法烟气脱硫工艺的优选。Limestone/gypsum WFGD technology the most common method used to reduce SO2 from power plant exhausting gas. It is very important to evaluate their performance and get the best technology. The multi-level fuzzy mathematics model is presented to evaluate the comprehensive performance of limestone/gypsum WFCD technologies for thermal power plants firstly. The factor aggregate includes environmental performance, economic parameters and technical performance, of which each consists of a few factors. Three different comprehensive evaluation methods are introduced. With combining the three comprehensive evaluation methods, five kinds of limestone/gypsum WFGD technologies are evaluated. The result according to the rule of Maximum Membership Value is advanced. The conclusion can help to choose the best limestone/gypsum WFCD technology.
