Electrostatic Precipitators (ESP)

Expertise from Extensive Experience in ESP Retrofits and Upgrades

ESP Fuel Tech Shop Fabrication

The rehabilitation of existing Electrostatic Precipitators (ESP) is a cost effective means of improving the performance of aging equipment, thereby regaining lost efficiency and meeting new, more stringent, particulate emission levels. Retrofits to ESP systems minimize capital expenditures; eliminate risks inherent when bringing new equipment on line, as well as, equipment down time by keeping outage requirements as short as possible.

ESP Design Expertise

Our systems are designed to match the physical layout of the existing ESP shell. In most cases, the original equipment can be enhanced with our improved designs for mechanical and electrical systems, including: collecting plates, discharge electrodes, electrical sectionalization, power supplies, control systems and rapping.

ESP DesignWe have had a great deal of success with complete or partial retrofits to wide plate spacing and rigid discharge electrode (RDE) configurations. Our strong background in flue gas conditioning (FGC) systems also compliments the ability to provide enhanced ESP performance guarantees.

Beyond this, we have both the physical and computational fluid dynamic (CFD) modeling capabilities along with proprietary numerical based ESP performance modeling which is the basis for determining performance guarantees. This includes ESPs where DSI systems for SO2, HCl or mercury control may require improved performance or where low rank fuels create particulate emissions challenges. As an established single-source supplier within the marketplace, we combine the best equipment concepts to develop an ESP system that is cost effective and reliable.
