Method and apparatus for controlling ammonia injection amount in activated carbon desulfurization and denitrification plant

摘要

A method for controlling the amount of ammonia injected in an activated carbon desulfurization and denitrification plant is provided. The method includes obtaining inlet flue gas state data, outlet flue gas state data, temperature-pressure compensated inlet flue gas flow rate and ammonia dilution air flow rate; A first, based on the inlet flue gas state data, the outlet flue gas state data, the temperature-pressure compensated inlet flue gas flow rate, the ammonia dilution air flow rate and the preset parameters, using a first preset calculation model Calculating a correction ammonia dosage; And calculating a first target ammonia injection amount corresponding to the first corrected ammonia injection amount using a second preset calculation model. Further provided is an apparatus for controlling the ammonia injection amount of activated carbon desulfurization and denitrification plants.
