摘　　要：为了应对火电机组深度调峰的常态化需求以及实现降碳减污的协同增效目标,降低脱硫系统氧化风机能耗,文章结合2×340 MW机组的氧化风机现有配置状况,提出了双塔双循环脱硫氧化风系统设备公用和风量母管制的改造方案。通过对脱硫氧化风需求量的精确计算,得到不同负荷水平和燃煤硫分条件下的脱硫氧化风需求量,为氧化风机在母管制和单元制之间的运行切换提供了坚实的理论依据。具体而言,在机组负荷为270 MW或燃煤硫分低于1.2%的情况下采用氧化风母管制运行方式,能够大幅降低脱硫系统能耗并有效提升设备备用余量。In order to meet the normalized demand for deep peak shaving of thermal power units and achieve the synergistic efficiency goal of carbon reduction and pollution reduction,and to reduce the energy consumption of the oxidation fan in the desulfurization system,this article proposes a renovation plan for the common equipment and air volume main pipe of the dual tower dual cycle desulfurization oxidation fan system based on the existing configuration of the oxidation fan in the 2×340 MW unit.By accurately calculating the demand for desulfurization oxidation air,the demand for desulfurization oxidation air under different load levels and coal sulfur content conditions was obtained,providing a solid theoretical basis for the operation switching of oxidation fans between the main control and unit systems.Specifically,when the load of the unit is 270 MW or the sulfur content of the coal is less than 1.2%,adopting the oxidation air main control operation mode can significantly reduce the energy consumption of the desulfurization system and effectively improve the equipment reserve capacity.
