| Abstract: | The paper introduces the technical process of the desulfurization by ammonia method, the hardware installment configu- ration of the DCS control system , the main analog control system of the SO2 and pH, sequence control system and continuous emission monitoring systems（CEMS）of flue gas emitted, The advantages and disadvantages of the DCS configuration are also comparatively analyzed. Related suggestion and scheme are put forward for the retrofitting of the innovational plan, and lay the groundwork for the control system of flue gas desulfurization. |
