基于经济环保性能的低氮燃烧智能闭环控制策略研制与应用

摘要

This paper analyzes various factors influencing the operation control of boiler low Nox combustion in coal-fired power plants.The design conception is elaborated for closed-loop control of low Nox combustion,and the control strategy is introduced based on optimal economic and environmental performance.The strategy has been exemplified by the actual application in a 300 MW coal-fired boiler in terms of the technical approaches and practical results.%分析了影响燃煤电厂锅炉低氮燃烧系统运行控制的因素,指出影响锅炉经济性的可变因素。阐述了低氮燃烧智能闭环控制的设计思想,并介绍了基于经济环保性能最佳的低氮燃烧闭环控制策略。介绍了该策略在某300 MW燃煤锅炉实施的技术路线与应用结果。
