Development and Application of Data-Driven Intelligent Optimization System for Boiler Air and Powder
In order to solve the problems of tra ditional combustion optimization adjustment and improve boiler combustion efficiency and environmental protection,a data-driven intelligent optimization system for boiler air and powder has been developed,including a monitoring device for coal powder flow rate and concentration,a coal powder flow rate adjustment device,a coal powder distribution balance device,and an automatic leveling control system.By introducing a circular array non-contact coal powder electrostatic field measurement technology,key parameters such as coal powder flow rate and concentration in the primary air duct can be accurately measured in real time.Through the coal powder flow rate adjustment device and coal powder distribution balance device,the flow rate and concentration of coal powder at the outlet of each burner can be adjusted or purposefully adjusted,and the distribution of coal powder entering the furnace combustion can be controlled,achieving a balanced amount of coal powder in each pipe under hot conditions.The automatic leveling control system outputs the optimal guidance parameters for combustion control,providing guidance to operators and completing the adjustment operation of the unit.In practical applications,this system has solved the problem of uneven distribution of coal powder,improved combustion efficiency,realized low NOx combustion,and achieved the expected goals.
