ESP (Electrostatic Precipitator (ESP))

Highly Efficient and Economical Dust Collection Solution

Electrostatic Precipitators (ESP) are advanced air pollution control systems used to separate very fine dust particles (ash, soot, etc.) found in the flue gases of industrial facilities and power plants with high efficiency.

Working Principle: Dust Collection Step by Step

ESPs are based on the principle of capturing particles with a static electric charge. This process occurs in three basic steps:

1. Particle Charging (Ionization): Dusty gas entering the filter passes past discharge electrodes to which high voltage is applied. These electrodes create an electric field called a "corona," which ionizes the gas molecules. Dust particles passing through this field become negatively charged.
2. Particle Collection: As negatively charged dust particles move with the gas flow, they are attracted to grounded, positively charged collection electrodes (plates). The particles adhere to these plates and are separated from the gas stream.
3. Particle Removal: The dust layer accumulating on the collection plates is shaken off by periodically operating mechanical rapping systems. Dust falling from the plates is collected and discharged into bunkers located at the bottom of the filter.

Main Components and Advantages

ESP systems are preferred especially in facilities with large volume gas flows thanks to their low operating costs and high efficiency.

• High Efficiency: It provides collection efficiency of over 99% even for very fine particles.
• Low Operating Cost: Because they cause very low pressure loss compared to bag filters, fans consume less energy. There are no consumable costs (bags, etc.).
• High Temperature Resistance: It can operate without any problems in high temperature flue gases.
• Main Components: The system basically consists of discharge electrodes, collection electrodes, shaker device and high voltage transformers.
