摘　　要：针对炼焦生产过程中缺少性能评估环节而难以确保过程优化运行的问题,提出了一种基于经济性能评估的炼焦生产过程优化运行方法.该方法在炼焦生产过程经济效益指标和焦炭质量过程性能指标对协调优化级进行性能评估的基础上,结合模型置信度,建立专家规则,及时修正经济指标预测模型;基于焦炭产量、炼焦能耗等经济指标,以焦炭质量和工艺条件为约束,对炼焦生产过程进行协调优化,使得炼焦生产达到良好的运行状态.仿真结果表明,所提方法能显著地提高焦炭产量、降低能耗.In coking process,the optimal operation cannot be ensured due to lack of performance assessment.This paper proposed an optimization operation method based on economic performance assessment for the coking process.Based on performance assessment with economic indicators and quality indicators,combined with the confidence level model,the expert rules were established to timely correct forecasting model of the economic indicators,or optimize the coke production process to achieve good operating conditions,while taking the economic indicators including coke yield and energy consumption as the goals,the cokes quality and mechanism conditions as constraints.The simulation shows that the method proposed in this paper can obviously increase coke yield and reduce energy consumption.
