燃煤烟气脱氮技术的模糊综合评价

摘要

On the basis of the comprehensive performance analysis on such five typical coal-fired flue gas denitrogenation technology as selective catalytic reduction method, selective non-catalytic reduction method, adsorption method, electron beam method, oxidation ad- sorption method, multistage fuzzy mathematical model about the comprehensive performance analysis on coal-fired flue gas denitrogena- tion technology has been established. Based on the mathematical model, fuzzy comprehensive evaluation has been performed on with the help of the five different kinds of coal-fired flue gas denitrogenation teehnology and the accurate evaluation results have been ob- tained on the principle of maximum membership, which has given rise to the most reasonable method of denitrogenation technology.%在对选择性催化还原法、选择性非催化还原法、吸附法、电子束法、氧化吸收法等5种典型燃煤烟气脱氮技术进行综合性能分析的基础上，建立了燃煤烟气脱氮技术综合性能评价的多级模糊数学模型。基于该数学模型，以5种燃煤烟气脱氮技术为实例进行了模糊综合评价，根据最大隶属度原则得到准确的评价结果，从而得出最佳脱氮技术方案。
