Electrostatic Precipitators (ESP)
Specifically Designed For Biomass Systems
Wellons’ Dry Electrostatic Precipitator (ESP) is specifically designed for cleaning particulate entrained in flue gases from biomass-fired energy systems. Whether integrated in а complete Wellons system, or as an addition to an existing biomass system, Wellons ESPs are designed for long life and low repair and maintenance costs.
Standard & Custom Sizes
Wellons has 18 standard ESP sizes (utilizing single or multiple fields). Custom designed models are available upon request.

ESP Test Platform
Wellons Canada can provide coпtiпuous emissioп moпitoriпg systems (CEMS) and opacity monitoring systems (COPS) for both пеw апd existing ESP’s. Operating data from the ESP and combustor can be displayed on a related emissions report, and integrate into Wellons computerized control system.
8 of 8Modular, Scalable, & Reliable
Wellons uses a modular, pre-engineered design approach. Using this results in a project specific ESP selection. Increased shop assemblies speeds site installations, and the use of proven components ensures high reliability.
Wellons’ ESPs are designed and manufactured to rigorous standards using design criteria and components with proven superior performance. Our design ensures stable high voltage operation for best particulate charging and crisp impact rapping to neatly remove ash from ESP internals.
High Frequency Power Supplies
(60kHz Vs 25kHz)
60 kHz provides higher collection efficiency and reduced capital cost.
Rigid Discharge Electrodes (RDEs) And Collecting Plates
Allow easy and quick alignment. This results in more precise electrode tolerances and higher, more consistent performance.
Rappers
Electric sledge hammer rappers dislodge all types of dry dusts using variable impact intensity and frequency.
Welded, Gas-Tight Enclosure
Integrated casing design for structural stiffening and tight-fitting thermal insulation prevents cold spots and corrosion.
Ash Augers & Hoppers
Dust is collected and continuously removed by heavy-duty ash augers and rotary airlock valves.
Optional Roof Enclosure
An optional roof enclosure is available to protect ESP components and facilitate ongoing maintenance in harsh environmental conditions.
Electrostatic Precipitators
Continuous Emissions Monitoring
Wellons provides Continuous Emission Monitoring Systems (CEMS) and opacity monitoring systems (COPS) for both пеw апd existing ESP’s.
Operating data from the ESP and combustor is displayed on a related emissions report, and integrated into Wellons computerized control system.
Electrostatic Precipitators
Engineering Support
Wellons uses its extensive biomass boiler system experience and past test results to accurately estimate flue gas flows and emissions from the ESP, including filterable and condensable particulate. Wellons engineers select the optimum ESP for each project and assist customers with emission analysis and related permitting.
