| Abstract: | An introduction is being presented to the application status of selective catalytic reduction （SCR） flue gas denitrification system in a 3 033 t/h boiler, together with an analysis on problems existing in the SCR denitrification process. To reduce the NOx emission, ammonia escape rate and ammonia injection rate, a series of retrofit measures were proposed and taken, after which good effects are obtained, such as reduced NOx emission, stabilized operation of the SCR denitrification system, etc. |
