Abstract:
Ammonia-adding apparatus and methods for ammonia-based desulfurization use multi-stage control, calculate a theoretical amount of ammonia based on gas amounts provided by an inlet continuous emission monitoring system (CEMS) and an outlet CEMS of the ammonia-based desulfurization device or associated gas amounts, a SO 2  concentration provided by the inlet CEMS, and a predetermined SO 2  concentration of the outlet CEMS. The apparatus and methods calculate a corrected theoretical amount of ammonia using half of the ratio of the actual amount of added ammonia to the actual amount of removed sulfur dioxide as a correction coefficient for the theoretical amount of ammonia; add an ammonia absorbent equivalent to the corrected theoretical amount of ammonia to the ammonia-based desulfurization device through an ammonia metering means and an ammonia control valve, and automatically control the actual ammonia flow rate based on the actual SO 2  concentration and a change trend provided by the outlet CEMS.

Claim (Index 47):
The apparatus of  claim 30  further configured to:\n measure at least one of:\n a gas amount corresponding to an inlet of the desulfurization system; and \n a gas amount corresponding to the outlet of the desulfurization system; and \n \n substitute the at least one measured one of the gas amount corresponding to the inlet and the gas amount corresponding to the outlet for the other one of the gas amount corresponding to the inlet and the gas amount corresponding to the outlet.
