Scope
This standard specifies the design requirements for wet flue gas desulfurization plants without bypass in thermal power plants. This standard applies to the simultaneous construction of limestone-gypsum wet flue gas desulfurization plants without bypass for new and expanded power plants with boilers of 670 t/h and above. The design of desulfurization plants without bypass added to existing power plants, desulfurization systems with existing bypass that need to cancel the bypass, or desulfurization plants for power plants with boilers below 670 t/h may refer to this standard for implementation; the design of other wet desulfurization plants may also refer to this standard.
本标准规定了火电厂无旁路湿法烟气脱硫装置的设计要求。本标准适用于670 t/h 及以上锅炉的新、扩建电厂同期建设的无旁路石灰石-石膏湿法烟气脱硫装置。已建电厂加装无旁路的脱硫装置、已建有旁路的烟气脱硫系统需要取消旁路或670 t/h 以下锅炉的电厂脱硫装置设计可以参照执行,其他湿法脱硫装置设计可参照执行。
