摘要

目前主流脱硝技术包括低NOx燃烧(LNB)、选择性非催化还原(SNCR)、选择性催化还原(SCR)和SNCR/SCR混合法等。针对具体脱硝项目

将经济学分析模型应用于脱硝技术的经济性评价

通过技术和经济性对比分析

总结出各脱硝工艺之间的技术差异和经济性差异。分析表明

LNB工艺投资和维护费用较低

对锅炉和煤种适应性强

为控制NOx的首选工艺。

Abstract

At present

the essential denitrification technologies include low nitrogen burning(LNB) technology

selective catalystic reduction(SCR) method

selective non-catalystic reduction(SNCR) method

and hybrid method of SCR and SNCR.Directing against concrete project of denitrification

the economic analysis model has been used for evaluating economic efficiency of denitrication technologies for coal-fired boilers.Through comparison and analysis of technical and economic efficiency

the difference in technical and economic aspects of different denitrification technologies has been summarized up.Analysis shows that the LNB technology has lower capital investment and maintenance expense

having strong adaptability to coal sorts used for boilers

being the first selection for NOx control.
