| Abstract: | This paper compares the traditional DCS and the new FCS,and it also expatiated a control system which is the combination of FCS and DCS,which is called FDCS in this paper,and it is applied in the process control system for flue gas desulfurization plants of fossil fuel power plants.In the paper,the characteristics and advantages of this control system is also expatiated.The application of S7-300 and PROFIBUS-DP in the project of flue gas desulfurization is discussed.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,the total investment cost is lowered down. |
