| With the continuous development of social economy, the total amount of nitrogen oxide emissions is increasing, so In the "twelfth-five " plan, The total amount of nitrogen oxide as one of the main control. pollutants is controlled。The thermal. power industry is the key industry to cut NOx emissions. issued emission standards for thermal power industry (GB13223-2011), Regulations for the implementation of 100mg/m3 emission standards for nitrogen oxides, Therefore, the construction of thermal power units must be carried out denitrification system. This paper is to review the relevant literature, To understand the construction and reform of the new thermal power units and the denitrification system of the active service unit, Through the analysis and comparison the two thermal power unitsthe investment and constructionã€online monitoring data〠central control system curve. Due to the Design service year, construction space, and the flue setting of the denitrification system of the active service unit, The new unit denitration system investment efficiency, stability, Operational efficiency, the removal rate of nitrogen oxides were better than that of active duty units denitration system, This paper is to provide the reference for the thermal power generating units in the reform of the denitrification system. At the same time, the paper discusses some problems, such as flue gas temperature and ammonia escape influence of SCR de NOx system, using urea as reducing agent of the SCR system winter pyrolysis furnace crystallization, large differences in online data, and Propose effective solution method. Therefore, it is of great significance to solve the problem of the construction and operation of the denitrification system in the thermal power industry. |
