AMMONIA INJECTION AMOUNT CONTROL METHOD AND APPARATUS FOR ACTIVATED CARBON DESULFURIZATION AND DENITRATION SYSTEM

摘要

An ammonia injection amount control method and apparatus for an activated carbon desulfurization and denitration system. The method comprises: obtaining inlet flue gas state data, outlet flue gas state data, a value of temperature and pressure compensated inlet flue gas flow, and ammonia diluting air flow; calculating a first ammonia injection amount correction value according to a preset first calculation model on the basis of the inlet flue gas state data, the outlet flue gas state data, the value of temperature and pressure compensated inlet flue gas flow, the ammonia diluting air flow, and a preset parameter; and calculating a first ammonia injection amount target value corresponding to the first ammonia injection amount correction value according to a preset second calculation model. Also disclosed is an ammonia injection amount control apparatus for an activated carbon desulfurization and denitration system.
