DeNOx System Control Tactics After Ultra-Low Flue Gas Emission Reformation of the First 1000MW Unit
The traditional coal-fired power plant has been regarded as the main source of air pollutants,and become the focal point of national environmental protection.As the first ultra-low flue gas emission devices put into operation in the 8th generator unit in Jiaxing Power Plant of Zhejiang Energy Group Company,the main pollutant emission indicator has been up to the standard of natural gas generator units,especially the NOx emission has been controlled below 50 mg/Nm3 all time.The thermal-control team has reformed the existing problems in the CEMS measurement of DeNOx system,the DeNOx automatic control tactics and so on,since the ultra-low emission environmental demonstration project was implemented in 1O00MW coal-fired units in Jiaxing Power Plant.This paper discusses this improvement measures and problems in the course of project operation.
