摘要： 随着人们环保意识的增强，电站锅炉的NO_x排放标准越来越严格。为了符合环保要求，有必要对燃煤电站锅
炉采取一系列脱硝降氮技术。概述了燃烧过程中NO_x的形成机理，分析了主流的NO_x控制技术，包括炉内控制技术和末
端控制技术，并对各种NO_x控制技术的优势和不足进行了总结。

Abstract: With the enhancement of environmental protection awareness among people, the NO_x emission standard of utility boilers
is becoming more and more strict. In order to meet the requirements of environmental protection, it is necessary to adopt a series
of denitration and nitrogen reduction technologies in coal-fired power station boilers. This paper summarized the formation mechanism
of NO_x during the combustion process, and introduced the mainstream NO_x control technology, including furnace control technology
and terminal control technology, and then summarized the advantages and disadvantages of various NO_x control technologies.

Key words: boiler; NO_x; air staging; reburning
