Optimization and Transformation of 600 MW Boiler Burner Based on Low Nitrogen Combustion Technology
There are mainly two types of methods for the treatment of NOx in coal-fired power plants:end treatment and source treatment.The combination of the two treatment methods(low nitrogen combus-tion+SCR)has achieved significant results in the renovation of existing power plants.Based on it,the for-mation mechanism of NOx in coal-fired power plants is introduced,the reasons for high NOx emissions from boilers are analyzed.Taking the 600 MW unit boiler as an example,the combustion system is transformed with low nitrogen combustion technology without changing the original SCR system.Through experiments,the changes in NOx emissions from boilers before and after the transformation,as well as the impact of transformation on boilers,are analyzed.
