摘　　要：火电机组为了配合我国能源“双碳”战略的实施,进行了灵活性改造和低负荷稳定运行,分析了某660 MW超临界机组切圆锅炉低负荷运行的数值模拟方法,通过煤粉燃烧、辐射、气固两相流等数学模型分析30%负荷下对流情况、燃烧情况和NOx的产生情况,为实际运行提供理论依据。In order to match with the implementation of energy "dual carbon" strategy,thermal power units need to be retrofitted for flexibility and stable operation at low loads. The numerical simulation method of low-load operation of a tangential boiler of a 660 MW supercritical unit is analyzed. Through mathematical models such as pulverized coal combustion, radiation, and gas-solid two-phase flow, the convection, combustion and NOxgeneration under 30% load is analyzed. The result can provide theoretical basis for actual operation.
