most of the automatic control of ammonia injection valve in domestic SCR ammonia spraying system exist certain problems.To solve this problems
this paper expounded the establishment method for a non-linear predictive model for NO_x concentration at the SCR system inlet
on the basis of deep component analysis.Moreover
combined with the fuzzy control and time delay compensation method
this model was applied to develop a new control strategy for ammonia injection.The result shows that
in both steady and dynamic state of the unit
the NO_x concentration at the stack outlet can be controlled within the range close to the setting value for a long time.So the problem of automatic operation of the ammonia injection in SCR system was effectively solved
