Fly ash is the fine particulate matter identified as environmental pollutant emitted from thermal power station. Self priming venturi scrubber is now-a-days getting importance for its high performance efficiency in case of nuclear power plant accident. Therefore, the present paper focuses on the control of fly ash particulate matter from the air using self priming venturi scrubber in both the condition, submerged and non submerged. Detailed investigation on the pressure drop inside the venturi scrubber and scrubbing of particulate matter has been discussed in the present study. It has been found from the experiment that the maximum pressure drop is observed at highest throat gas velocity of 72 m/s, water level height of 0.77 m. Maximum removal efficiency of fly ash, 99.89% is obtained at throat gas velocity of 60 m/s, water level height of 0.77 m with fly ash inlet concentration of 0.3 x10⁻³ kg/Nm³ in submerged condition. Furthermore, empirical model has been developed to validate the experimental results of pressure drop and removal efficiency and compared with the existing mathematical model.

粉煤灰是从火力发电厂排放的被确定为环境污染物的细颗粒物。自吸式文丘里洗涤器由于其在核电站事故中的高性能而变得越来越重要。因此，本文着重于在淹没状态和非淹没状态下使用自吸式文丘里洗涤器从空气中控制飞灰颗粒物。在本研究中，已经对文丘里洗涤器内部的压降和颗粒物的洗涤进行了详细研究。从实验中发现，在最高喉道气体速度为72 m / s，水位高度为0.77 m时观察到最大压降。喉气速度为60 m / s，水位高度为0时，粉煤灰的最大去除效率为99.89％。淹没条件下为^-3 kg / Nm ³。此外，已经开发了经验模型来验证压降和去除效率的实验结果，并将其与现有的数学模型进行比较。
