Electrostatic Precipitator (ESP) Upgrades & Modernization – Engineering Solutions

Extending the service life and sustainably improving the performance of existing electrostatic precipitators requires a holistic engineering approach that integrates process engineering, mechanical design, as well as modern high-voltage technology and control systems.

AB Clean Air Solutions supports plant operators with technology-neutral concepts for the modernization and performance optimization of electrostatic precipitators. Typical engineering focuses include retrofit concepts, TR upgrades, gas distribution optimization, energy efficiency measures, and solutions to meet modern emission limits — while retaining existing steel structures and minimizing downtime.

The scope of services includes engineering concepts to increase efficiency, CFD-based gas flow optimization, modernization of electrical equipment, as well as mechanical and structural modifications — all tailored to specific process conditions in cement plants, power plants, sinter facilities, steel plants, and other industrial applications.

Modern ESP upgrade concepts enable:

• Reduction of dust emissions to < 10 mg/Nm³
• Improved energy efficiency through optimized high-voltage systems
• More stable process operation under fluctuating gas volume flows
• Extended equipment lifetime through targeted retrofit engineering measures
