The Control Of NO_x Emission Of Coal-fired Boiler

In this paper,the analysis of features of China’s energy structure as well as the trend of electric power industry development is completed.A conclusion is deduced that it is urgent to control the emissions of pollutants generated by coal-fired power plant,because coal-fired power generation is an important part of China’s energy structure,the proportion of which will not change sharply in coming decades.First of all,the main pollutants analyzed are nitrogen oxides,whose production mechanism,influencing factoes and the main control technology used at current is elaborated in details.Besides,the combustion adjustment test is HUANENG Beijing thermal power plant in 2013 has been used as an engineering example,detailed interpretation of the combustion adjustment process and its achievements has also been presented,come to the conclusion that the nitrogen oxides emissions can be greatly reduced by certain combustion adjustment.In addition,some opinions and suggestions about energy saving and emission reduction has been proposed in the paper.
