Simulation Study Of Scr Flue Gas Denitration Device Optimization Controi On Coal—fired Power Plant

In this paper, flue gas denitrification technology is studed, and the best solution way is Selective Catclytic Reduction,mainly through the learning of current technological and socio-economic development.This paper uses SCR flue gas denitration system as the research object, Taking denitration device in the300MW coal-fired power plant for example, The simulation and the operation of SCR method is studied particularly. By comparing the current present situation of the gas denitration technology and typical method of flue gas denitration, the different arrangement of device in SCR flue gas denitration for is discussed,and the form of layout and type of equipment is selected, then the datas of the300MW coal-fired power plant is optimized. Through the selected device and arrangement,300MW coal-fired power plants SCR denitration system is simulated by VB, And at the same time editing animation and developing the software, the system operation of the coal-fired power plant denitration can be learned.By the research of SCR denitration,flue gas flow parameters, including SCR reactor、ammonia storage supply system and a series of corresponding mathematical model simulation is established.In the simulation, based on the mathematical model, the simulation software is developed by using VB6.0.And, the simulation computation windows are compiled to calculate the parameters of flue gas, Finally parameters optimization is achieved, the optimized parameters in simulation reflected in operation,making it easy to control.Development of SCR simulation software will run on windows starts system independent operation.. The simulation software can be used for teaching and for operation and maintenance personnel training, and reduction of the operation in power, and is optimized for the safe operation of the equipment efficiency, to provide the reference.
