Abstract

A method for controlling an ammonia injection amount of an activated carbon desulfurization and denitrification system is provided. The method includes: acquiring inlet flue gas status data, outlet flue gas status data, a value of a temperature-pressure compensated inlet flue gas flow and an ammonia dilution air flow, calculating a first 10 correction ammonia injection amount by using a preset first calculation model, based on the inlet flue gas status data, the outlet flue gas status data, the value of the temperature-pressure compensated inlet flue gas flow, the ammonia dilution air flow and preset parameters, and calculating a first target ammonia injection amount corresponding to the first correction ammonia injection amount by using a preset 15 second calculation model. A device for controlling an ammonia injection amount of an activated carbon desulfurization and denitrification system is further provided.
