锅炉磨煤机分离器及其控制系统改造OA

To address the problems of low adjustment precision,inability to perform online ad-justment,and high failure rate of the static separator in the coal pulverizing system of a boiler in a steel plant's captive power plant,a modification of the dynamic separator for the coal mill was imple-mented,and the control system and network architecture were optimized.Through the hardware and software modification of the DCS system,remote variable-frequency speed regulation of the separa-tor motor and efficient control of pulverized coal fineness were realized.The operation results show that the modification scheme significantly improves the economy and environmental friendliness of the pulverizing system,which provides important reference value for reducing power generation costs and promoting sustainable development of the enterprise,and can also be used as a reference for similar modifications in other power plants.
