Is electric heating necessary for the hopper at the bottom of the electrostatic precipitator?
Thread Content
Is it necessary to install electric heaters in the conical hopper at the bottom of the electrostatic precipitator in coal-water slurry boilers? Such heaters were included in the original design, but they are now damaged, in the Shandong region
It is necessary to add this, as the purpose is to prevent moisture from condensing at low temperatures and causing dust accumulation; in severe cases, this can lead to a short circuit in the electrical field grounding
Conical hoppers are generally equipped with electric heating. There are different types of electric heating systems available: some use heating cables, while others use PTC heating plates. Which type did you choose for your design?
We used heating plates, but after prolonged heating, the steel plates got damaged; it wasn’t noticed at first. However, when no heating was used, there were no problems either
