| Abstract: | This paper describes the craft of wet limestone-lime flue gas desulfurization briefly and discusses the selection of main equipment and gauges. It also discusses the construction of control system and the realization of main functions. The problems of liquid level control and pH value control are solved. The stability of the system is increased, the efficiency of desulfurization is guaranteed, and the total investment cost is lowered down. |
