摘　　要：为进一步提升电网对可再生能源发电量的消纳水平,提高电网低谷运行的可靠性,开展了燃煤机组最小出力运行方式的核定研究。基于电站锅炉切圆燃烧机理与运行调整技术,并兼顾安全、稳定、环保、节能等指标,进行了最小出力稳定性评价方法探讨,并在示范机组完成了25%额定负荷的稳燃能力评价,以供同类进行借鉴。In order to further enhance the consumption level of renewable energy generation by the power grid and improve the reliability of power grid operation at low ebb,the verification research on the operation mode of minimum output of coal-fired units was carried out.Based on tangential combustion mechanism and operation adjustment technology of power plant boilers,and taking into account safety,stability,environmental protection,energy saving and other indicators,the minimum output stability evaluation method was discussed,and the stable combustion ability of 25%rated load was evaluated in the demonstration unit,aiming to provide reference for similar situations.
