火电厂脱硫增容改造系统优化

Optimizations of Rehabilitations for Wet Flue Gas Desulfurization Systems of Thermal Power Plants

随着电厂燃煤含硫增加以及国家对火电厂大气污染物排放标准更为严格,电厂早期所上的脱硫装置已经很难适应煤种变化及新标准的要求。火电厂脱硫增容改造迫在眉睫。该文论述了电厂脱硫各系统增容改造、部分测量仪表优化以及运行中药剂的添加。

The FGD devices of thermal power plants were difficuk to adapt as the sulphur content in coal increasing and the standards for the discharge of atmospheric pollutants tightened. Therefore, rehabilitation for wet flue gas desulfu- rization system was extremely urgent. Rehabilitation for wet flue gas desulfurization subsystems, optimizations of some measuring instruments and additives＇ supplying during service were discussed.
