摘要
为了有效控制燃煤电站锅炉NOx的排放、保证锅炉高效率运行,运用模糊综合评价法建立了锅炉系统能效与污染物排放综合评价模型,对电站锅炉系统运行实施有效的控制。利用热效率及氮氧化物的预测优化模型确定包含经济性和环保性多级评价指标的隶属度函数;选用序综合法和熵权法确定指标权重;并利用某实际运行锅炉的数据验证了评价结果的准确性,为确立切实可用的协调能效与大气污染物排放的锅炉系统综合评价方法奠定基础。
In order to effectively control the NOx emission of coal-fired power boilers and ensure the high efficiency of boiler operation,in this paper the fuzzy comprehensive evaluation method is used to establish a comprehensive evaluation model for energy efficiency and pollutant discharge of power boiler systems,and to implement effectively the control of power boiler system operation.The thermal efficiency and nitrogen oxide prediction optimization model is used to determine the membership function of multi-level evaluation indicators including economic and environmental factors.The order synthesis method and the entropy weight method are used to determine the index weight.And the evaluation results are verified by using the data of an actual operating boiler.So the foundation of a comprehensive evaluation method is established for boiler systems that can coordinate energy efficiency and atmospheric pollutant emissions.
