摘要
为提高HXD燃烧炉温度的稳定性,通过研究燃烧炉热容过程的影响因素,建立了基于PID与误差补偿的炉温控制模型,并运用DOE试验获得最佳参数值,实现了燃料阀门开度对温度偏差和变化速率的快速响应。结果表明:1炉温波动大幅度减小,标准偏差值由12.31下降至4.83,过程控制能力指数Cpk值由0.68提高至1.49。2提高了工艺气温度的稳定性,HXD烘丝出口水分标准偏差由0.21降低至0.14,达到烟草行业先进水平,充分保障了卷烟产品的内在感官质量。
To improve the stability of HXD furnace temperature, this paper establishes furnace temperature control system based on PID and error compensation through analyzing the affecting factors of heat process of furnace and realizes the quick response of fuel value opening degree to temperature deviation and change rate with adoption of DOE experiment to attain best pa- rameters. Results show that 1. The fluctuation of furnace temperature is greatly reduced,standard deviation decreases from 12. 31 to 4. 83 and Cpk value of process control ability index increases from 0. 68 to 1.49. 2. Improve the stability of process temperature and the water standard deviation at HXD drying wire outlet decreases from 0. 21 to 0. 14, which achieves the advanced level of tobacco industry and fully guaranteed the internal sensory quality of cigarette products.
