Embodiment Construction
[0035] see figure 1 , figure 1 It is a schematic flow chart of the optimal control method for the SCR denitrification system of the present invention.
[0036] The method for optimizing the control of the SCR denitrification system comprises the following steps:
[0037] S101, when the nitrogen-ammonia ratio is greater than 1 and less than 1, measure and obtain NO reflection parameters of the SCR denitrification system at a preset temperature;
[0038] S102, calculate the apparent reaction rate constant K of NO at each temperature when the nitrogen-ammonia ratio is greater than 1 according to the following formula NO :
[0039] K NO = - u ln ( 1 - η ) ( 1 - ε ...
