火电厂氮氧化物“零超排”管控措施研究

Study on Control Measures of"Zero over Discharge"of Nitrogen Oxides in Thermal Power Plant

目前随着经济的发展对于电量的需求变得越来越大,火电厂的压力也随之变大,火电厂的燃煤量在一定程度上大幅的增加,因此,产生的污染也是越来越严重。为了更好的处理好氮氧化物的污染问题,目前,主要采用的三种方式是燃烧、燃料脱氮以及烟气脱硝。主要对火电厂燃烧产生的氮氧化物管理现状进行了相应分析,然后再根据国家氮氧化物治理和排放政策,对火电厂氮氧化物零超排的管控措施提出了建议。

At present,with the development of economy,the demand for power has become greater and greater,and the pressure of thermal power plants has also become greater.Naturally,the coal consumption of thermal power plants will increase significantly to a certain extent.Therefore,the pollution is becoming more and more serious.In order to better deal with the problem of NOx pollution,at present,the three main methods are combustion,fuel denitrification and flue gas denitrification.This paper mainly analyzes the current situation of NOx management generated by combustion in thermal power plants,and then puts forward constructive suggestions on the control measures of zero over emission of NOx in thermal power plants according to the national NOx control and emission policies.
