Abstract: Abstract:The main design idea and technology roadmap of the lignite blending and costbenefit analysis operating system were introduced. Through the system, the collected lignite management messages can be transferred into the mastercontrol room, and there the messages are used to help the production personnel to analyze the operation condition, the production cost and technical indexes comprehensively and to adjust the lignite blending ratio rationally. So the unit operation was optimized, and the best lignite blending scheme was obtained to help the power generation enterprise to obtain maximum economical benefit.
