Abstract
At present,the selective catalytic reduction(SCR) method for flue gas denitrification has not been popularized in large-scale coal-fired power plants,thereby,the experience in operation and control of SCR flue gas denitrification systems is comparatively insufficient.For this,the normal start-up,shutdown,and stop through automatic protection,as well as the main control mode in their operation process have been presented,providing guidance for safe and stable operation of the SCR flue gas denitrification systems.
