METHOD AND DEVICE FOR CONTROLING AMOUNT OF AMMONIA INJECTION OF ACTIVATED CARBON DESULFURIZATION AND DENITRIFICATION SYSTEM

摘要

It is a method of controlling an ammonia injection amount from an activated carbon desulphurization and denitrification system. The method includes: acquiring input flue gas situation data, output flue gas situation data, a value of a temperature and pressure compensated inlet flue gas flow and an ammonia dilution air flow, calculate a first amount of ammonia injection for correction using a first predefined calculation model, based on the input flue gas situation data, in the exhaust flue gas situation data, the value of the inlet flue gas flow compensated by temperature and pressure, ammonia dilution air flow and predefined parameters, and calculating a first target amount of ammonia injection that corresponds to the first amount of ammonia injection for correction using a second predefined calculation model. A device for controlling an ammonia injection amount of an activated carbon desulphurization and denitrification system is also provided.
