浅谈湿法烟气脱硫系统的控制及就地测量仪表的选型

Discussing the Control of the Wet FGD System and the Selection of Measuring Instruments

燃煤发电厂烟气净化系统中测量仪表的适当选型,对于监视和控制整个工艺过程至关重要,既要满足控制系统的配置要求,又要考虑被测量仪表的精度要求,使污染物排放的参数测量符合有关法规及环保部门的要求。湿法烟气脱硫系统的工艺过程较为复杂,因此对仪控设备的选型及安装需要充分考虑FGD系统的特殊性。

The proper selection of measuring instruments of FGD system in coal-burning power plant is vital to supervising and controlling the whole technological process. The instruments should meet the distribution requirement of control system and also make the pollutant discharge fit the requirement of the related laws and environmental protection. Because the technological process of wet FGD system is very complicated, the selection and installment of the FGD control system should agree with the characteristics of the FGD system.
