Limestone / Gypsum Wet Flue Gas Desulfurization Control System Design And Optimization

Limestone (lime) / gypsum wet flue gas desulfurization (wet flue gas desulfurization , as FGD) technology has been the development of several decades of history, but because of its complex chemical reaction process, operating costs are high, making the desulfurization equipment to the market operators Facilities. This paper introduced thermal power plant in Limestone (lime) / gypsum wet FGD the process on the basis of a detailed analysis of the desulfurization plant characteristics, control theory, and desulfurization control system design and integration in the actual operation The problem and control system optimization strategies and methods.FGD process commonly used in the control system and the traditional control system similar to systems based on the PID control experts. By the experts in the areas of electrical, maintenance, thermal control, operation, and other professional experts and technical staff jointly formulated suitable for FGD process control strategy. Despite the design under ideal conditions optimized the various parameters, but the actual operation process, the coal boiler, load and volume of smoke, flue gas temperature, dust concentration, such as absorbent quality is constantly changing, if in accordance with the original Design parameters of operation, may affect the safe operation of generating units and desulphurization system itself of operation, the serious desulphurization system simply can not run. Should therefore be based on the actual situation to optimize the operation so that the desulfurization system performing at its best, improve the utilization of desulphurization system and security, reduce operating costs is a very practical significance of the topic.A design suitable for FGD process control strategy should be the basis for the use of FGD control system operating data and data on the use of those running the experience of experts to develop appropriate control strategies, based on the actual situation, after the use of the system is running in the scene Operation data were adjusted. But at this stage in the FGD system operational control equipment on the optimization of investment are not many, the massive operation at present is only used as a data history and the basis for the evaluation of FGD system.The purpose of this study is the use of the method of mining rules of the massive data mining operation, to explore the potential of the FGD system operation, control of the FGD system optimization, to achieve the maximum to reduce operating costs.
