RF Level Switch for ESP Fly Ash Hoppers

In thermal power plants, ESP hoppers are used to collect fly ash which is generated from the burning of coal. Since coal burns continuously in these plants, the exhausting gases contain high amounts of fly ash. The fly ash is, hence, collected by the boilers. These boilers contain economizers that work on the principle of gravity. Yet, a large amount of fly ash still manages to escape, and hence additional plates are placed to collect the fly ash. These plates are placed horizontally and are known as Electrostatic Precipitator (ESP) Hoppers.
