What is Electrostatic Precipitators (ESPs)?
Gas Cleaning Plants - Electrostatic Precipitators (ESPs)
The flue gases from Sponge Iron Kilns/AFBC or WHRB Boilers are carrying lot of suspended dust particles which are harmful to nature & not permissible by Pollution Control Board. There are many ways to treat these gases but the way that is proven & widely accepted globally is Electrostatic Precipitators (ESP). This is so because of
- Its unbeatable gas cleaning efficiency (Outlet Emission achieved as low as 50 mg)
- Low energy consumption because of low pressure drop across ESP (Only 15-20 mm of water gauge)
- Low Maintenance cost
Principle of Operation of ESP:
It works on precipitation principle where dust particles are charged by a flow of ions from
the discharge electrode& drift under the influence of the electrical field towards collecting electrode. The dust then dislodged through the effective Rapping mechanism.
