| 摘 要： | 湿式石灰石/石膏烟气脱硫(FGD)是燃煤电站占主导地位的脱硫方法,目前FGD系统中吸收塔液位的测量方式、测量精度存在较大误差,故提出加设压力监测点的方法来提高测量准确性,并在现场应用中得到验证,由此导出的公式可以用于防止吸收塔发生溢流起泡现象.

| Abstract: | The wet FGD(flue gas desulfurization) plays a predominant role in desulfurization of coal-fired power plant around the world.Currently,measuring mode and precise of absorption tower liquid level is not satisfying.The reason for this was analyzed and an improvement approach using pressure monitoring is proposed in the paper.The proposed approach has get field test.Field data shows that precise of liquid level increases notably using an additive pressure measurement at absorption tower.The formula derived fro... |
