摘　　要：在“双碳”目标背景下,环保要求日益严格,甲醇作为公认的高效清洁低碳燃料越来越受到重视。为分析甲醇用于锅炉燃料的可行性,建立了甲醇、煤、柴油、天然气作为锅炉燃料的综合性评价模型,通过层次分析法(analytic hierarchy process,AHP)、熵权法(entropy weight method,EWM),考虑节能性、环保性、经济性以及社会性4个指标,在各指标重要程度不同的5种情景下进行综合评价,得出以下结论:甲醇的节能性优于其他燃料,环保性及经济性与天然气相当,社会性方面仅次于煤,是柴油3.2倍、天然气的2.2倍;在重要性方面,环境因素第一,经济因素与节能因素其次,社会因素重要性最弱(情景3);甲醇作为锅炉燃料的综合评价得分为0.3186,与天然气(0.2929)、煤(0.2324)、柴油(0.1561)相比具有较大优势。Under the background of the goal of“carbon peak and carbon neutrality”,environmental protection requirements are becoming increasingly stringent,and methanol as a recognized high-efficiency,clean and low�carbon fuel has received more and more attention.In order to analyze the feasibility of methanol for boiler fuel,a comprehensive evaluation model of methanol,coal,diesel and natural gas as boiler fuel was established,and the four indicators of energy saving,environmental protection,economy and sociality were considered through analytic hierarchy process(AHP)and entropy weight method(EWM),and comprehensive evaluation was carried out under five scenarios with different importance of each index.The following conclusions are drawn:the energy saving of methanol is better than that of other fuels,the environmental protection and economy are comparable to natural gas,and the social aspect is second only to coal,which is 3.2 times that of diesel and 2.2 times that of natural gas;in terms of importance,environmental factors first,economic factors and energy-saving factors second,social factors are the weakest importance(scenario 3);the comprehensive evaluation score of methanol as boiler fuel is 0.3186,which has great advantages compared with natural gas(0.2929),coal(0.2324)and diesel(0.1561).
