灵活性改造机组电锅炉配置及优化策略

Electric Boiler Configuration and Optimisation Strategies for Flexibility Retrofit Units

针对低负荷情况下的稳燃、低负荷脱硝以及热电解耦等问题,总结了一系列可靠且成熟的解决方案。从目前我国燃煤机组运行现状出发,结合火力发电厂锅炉特点,阐述了灵活性改造的必要性,并对电厂的运行方式和技术特点进行分析。针对低负荷条件下的燃烧稳定性、低负荷脱硝等问题,提出了相应的解决方案。

A series of reliable and mature solutions have been summarised to address the issues of stable combustion,low load denitrification and thermo-electric decoupling under low load conditions.Starting from the current operation status of China's coal-fired units and combining the boiler characteristics of thermal power plants,the necessity of flexibility modification is elaborated,and the operation mode and technical characteristics of power plants are analysed.Corresponding solutions are proposed for the problems of combustion stability under low load conditions and low load denitrification.
