| 摘 要： | 研究了JN43型炼焦炉对象特性,将广义预测控制应用于立火道温控中,由于采用直接算法,减少了在线计算量。该控制算法较好地解决了由于装煤量、结焦周期、配煤水分等因素引起的炉温波动,运行结果表明:炉温变化由原来的±10℃减少到±5℃,年平均节煤气量约为1 032万m3,节能量达3.1%。

| Abstract: | On the basis of having studied the characteristic of JN43' coke oven, Generalized predicative control algorithm has been designed for coke oven heating control system, by using of direct algorithm, calculate work on line is reduced. the control algorithm preferably settled down the fluctuation of flue temperature due to some factors,like as the amount of coal, coking period, the moisture in compound coal and so on. the results show that the fluctuation of flue temperature reduced from ±10℃ to ±5℃, and annual average economized BFG capacity for 1 032 m3, the energy saving is 3.1%. |
