Electrified Gravel Bed Precipitator (EGB)
Eka Synergy Projects is one of the trusted electrified gravel bed filter manufacturers in India, offering cutting-edge Electrified Gravel Bed Precipitator (EGB) systems. Our EGB units serve as high-performance dry electrostatic precipitator systems designed for fine particle removal and final-stage flue gas cleaning.
These systems are engineered to capture sub-micron particulates, sticky tars, and alkali-rich dust in challenging combustion processes. Whether for palm biomass boilers or distillery waste incinerators, our EGB filters deliver exceptional collection efficiency and regulatory compliance.
What Is an EGB?
An Electrified Gravel Bed Precipitator (EGB) is a specialized type of dry electrostatic precipitator system that uses a high-voltage field across a gravel bed to trap ultra-fine particles and tars. It acts as a polishing filter, particularly effective with high-resistivity dust and alkali-laden emissions.
Features of Our Electrified Gravel Bed Precipitator (EGB) Systems
As a trusted construction company in Trichy, Eka Synergy Projects stands out for its end-to-end building solutions, delivering value-driven outcomes across residential, commercial, and smart city segments.
High Efficiency in Capturing Fine and Sub-Micron Particles
Our EGB units are designed to effectively capture even the smallest particulates, including PM2.5 and sub-micron dust. This makes them ideal for use as polishing filters in applications where ultra-clean emissions are required.
Excellent for High-Resistivity Dust
Perfectly suited for sticky and high-resistivity dust environments such as spent wash, lignite, palm shell, and biomass-fired boilers. EGB systems excel where conventional ESPs struggle.
No Wastewater or Sludge Generation
As a dry filtration method, the EGB avoids creating additional environmental hazards. There’s no dirty water, sludge, or mud—ensuring a cleaner, more sustainable operation.
Low Energy Consumption and Low Maintenance
The EGB electrostatic precipitator system uses minimal power and has fewer moving parts, resulting in lower operating costs, simplified maintenance, and greater long-term reliability.
Modular Design: 10,000 to 300,000 m³/h per Unit
Our EGB systems are scalable and modular, handling wide airflow ranges—from small industrial units to large-scale plants. This modularity enables easy upgrades and faster installations.
Uniform Gas Flow and No Slipstream Losses
The system ensures even gas distribution across the gravel bed, eliminating slipstreams and dead zones, which are common problems in conventional systems—leading to higher collection efficiency.
Proven for Upgrading Existing ESP Installations
Our electrified gravel bed filters are commonly used to retrofit or enhance underperforming ESP systems, allowing clients to meet tight air quality regulations without completely replacing legacy equipment.
Applications of Electrified Gravel Bed Precipitators (EGB)
Eka Synergy’s Electrified Gravel Bed Precipitator systems are trusted across a wide range of industries for effective removal of fine and sticky particulate matter in high-resistivity dust environments.
Distillery Boilers (Spent Wash Firing)
Ideal for removing sticky tars and fine particles from flue gases in distilleries using spent wash as fuel — a common source of challenging emissions.
Palm Shell / EFB Biomass Boilers
Perfect for biomass-based boilers that burn palm shell, empty fruit bunch (EFB), or palm fiber. Our EGB technology handles alkali-laden, high-resistivity dust with ease.
Coal & Lignite-Fired Power Plants
EGB systems are used as polishing filters in lignite and coal-fired power plants, often retrofitted to existing ESP systems to meet stringent emission norms.
Chemical & Fertilizer Plants
Industrial units handling fine powders, vapors, or hazardous byproducts benefit from our electrostatic precipitator systems to reduce air pollution and improve plant safety.
Paper & Pulp Mills
Effective in treating emissions with high organic content, our systems reduce visible emissions and support clean production in the paper industry.
Cement & Steel Manufacturing Units
Our EGB filters ensure the capture of ultra-fine particulates released from kilns, furnaces, and sintering units in cement and steel production.
Sugar Industry
In sugar mill boilers, especially those using bagasse or biomass, electrified gravel bed filters help control particulate emissions and ash residues.
Food Processing Units
Designed for safe air handling in food production facilities, the EGB system controls dust from drying, roasting, or combustion processes.

Frequently Asked Questions – Electrified Gravel Bed Precipitator (EGB)
1. What is an Electrified Gravel Bed Precipitator (EGB)?
An Electrified Gravel Bed Precipitator is a type of dry electrostatic precipitator system designed to remove fine particulate matter, tars, and sub-micron dust from flue gases. It’s especially effective in high-resistivity dust environments like distilleries and biomass boilers.
2. How does an EGB differ from a conventional ESP?
Unlike conventional ESPs, an EGB system uses a bed of electrified gravel to create a strong electrostatic field, ensuring higher efficiency for sticky, alkali-rich, or high-resistivity dust. It also does not generate sludge or wastewater.
3. In which industries is EGB commonly used?
EGBs are ideal for:
- Distillery waste-fired boilers
- Palm shell & EFB biomass boilers
- Coal & lignite-fired power plants
- Cement, steel, sugar, and chemical industries
4. What is the typical airflow capacity of an EGB?
Each EGB module can handle air volumes ranging from 10,000 to 300,000 m³/h, and multiple modules can be configured to scale based on plant capacity.
5. Is EGB suitable for emission norm upgrades?
