摘　　要：焦炉加热优化串级控制系统(简称OCC系统)采用以炉温反馈控制为主,前馈、反馈相结合的优化控制方案。为了提高控制精度和灵敏度,开发了炉温反馈与焦饼中心温度反馈的主、副双反馈调节方法,已在多个焦化厂得到成功应用,节能率提高了2.48%～4.06%,取得了明显的经济效益和社会效益。The optimized control of coke ovens（OCC） that taking oven temperature feedback control as primary,and combining feed forward,feedback controlling methods were adopted in study on the optimizing cascade control of coke oven heating system.Oven temperature and central temperature of coke cake main-side double-feedback adjusting methods were developed recently to improve controlling precision and sensitivity.It was used in some of coking pants,and energy saving rate is up to 2.48%~4.06%.It obtains obvious economic and social benefits with the OCC system.
