摘要
针对巴陵石化热电装置制粉系统电耗偏高、煤粉细度不稳定、控制参数波动大等诸多问题,通过理论分析和实验相结合的方法,研究系统的最佳运行工况,再以非线性控制理论为基础,对整个制粉系统实施全局自动控制,确保制粉系统严格工作在最佳工况区域以及该制粉系统的长期可靠运行。有效地控制了煤粉的均匀度,降低了制粉电耗,减少了炉水排放,锅炉热效率提高1.62%。
Because Baling Petrochemical thermoelectric devices have consumption of milling system, the unstable fineness of pulverized the problems： the higher power coal, the instability of control parameters etc., the pulverized coal system reliable running condition were researched with theoretical analysis and experiment. Then based on non-linear control theory, the global automatic control of the entire milling system was implemented. It didn＇ t only keep the pulverized coal system working on the best condition but also longterm and reliable running. The control system presented in this paper controlled the coal uniformity effectively, reduced the milling power consumption, reduced emissions of boiler water and increased boiler thermal efficiency by 1.62% .
