Transformation And Performance Test Of SCR Denitrification System In Panshan Power Plant

With the country's environmental standards increasingly strict,the country puts forward more and more high environmental protection requirements to the NOx emission concentration of the flue gas of coal-fired units.The main means of reducing NOx in flue gas of coal fired boiler is boiler flue gas denitrification and low nitrogen combustion in the furnace.In this paper,the existing technologies of flue gas denitrification in coal fired power plants are summarized,And the Panshan Power Plant data acquisition system after the use of denitration?performance analysis and experience summary.First,in this paper,the present situation of the diversity and industrialization of the denitrification process is analyzed,and the technology of denitrification at home and abroad is introduced.According to the national implementation of the "safe and reliable,in line with national conditions,advanced application" of the power construction policy,on the basis of ensuring the design of flue gas denitrification system meet the requirements of the latest national environmental protection emission standards,combined with the current situation of boiler type and system arrangement,overall planning,determine the optimal design scheme.Secondly,In the light of low nitrogen combustion system transformation denitration system in Panshan Power Plant ? data collection of the operation of flue gas denitrification equipment transformation,find out the method of optimizing the operation of the boiler by the synergistic effect of low NOx combustion and flue gas denitrification.Again,in order to meet the characteristics of flue gas discharged from the boiler,the air preheater is modified in Panshan Power Plant.The article analyzes the impact of SCR denitrification device on air preheater,practical experience is summed up.Last,in this paper,the safety and economic operation of the post denitrification operation are summarized and evaluated.In this paper,the influence of SCR denitrification system on boiler safety and economic operation is studied,expect the research results can be applied to the actual production work,At present,the operation of the denitrification system has a certain guiding significance.
