Design And Implementation Of Circulating Fluidized Bed Boiler Control System Based On Pks

Circulating Fluidized Bed Boiler(Referred to as CFB boiler)is developed in recent decades a new type of clean combustion technology,CFBB applications in power is becoming more and more common for its attractive advantages of high combustion efficiency,efficient sulfur removal,low NOx emission,fuel flexibility and good load-following capability.The commonly used control method cannot effectively control the circulating fluidized bed boiler which needs a coordinated control system with distribution parameters,non-linearity,time dependence,and long time lags.In this paper,CFB boiler control some of the key issues of distributed control system(DCS) research and development of CFB boiler to improve the level of automation and control to do a useful experiment.This article about the DCS systems design engineering case of a company in the aluminum thermal power plant.Combination of a circulating fluidized bed boiler technology characteristics on the use of Honeywell Experion PKS platform CFB boiler design of distributed control system,configuration and debugging process.At first,the paper introduces the characteristics of CFB boiler technology,followed by a detailed description of the control system configuration of the structure and selection of CFB boiler.Of the CFB boiler combustion control,drum water level control and main steam pressure control program carried out research and analysis,and finally on the basis of design method of control system configuration and system debugging.In actual operation,the system achieved good control effect. Through the understanding of the article can be carried out based on the Experion PKS circulating fluidized bed boiler DCS system design and configuration process,as well as effective control system.In this paper,for circulating fluidized bed boiler for the distributed control system design,control strategies,as well as custom method configuration process from a certain significance.
