<p>The present invention relates to a method for controlling multiple SCR denitrification systems for denitrifying exhaust fumes and, more specifically, to a method for controlling multiple denitrification systems using one outlet analyzer whereby, in the step of successively measuring, by using the one outlet analyzer, the amounts of nitrogen oxides contained in exhaust fumes lastly emitted from respective exhaust pipes during the actual operation of the multiple denitrification systems, the predetermined injection amounts of reducing agents for the respective denitrification systems are corrected by comparing the measured values with a reference value for nitrogen oxide emission, and thereby proper injection amounts of the reducing agents for the respective denitrification systems can instantly be changed/controlled in accordance with real-time changes in conditions.</p> |
