CFD Modeling

Electrostatic precipitators rely on electrostatic attraction to collect particles from a stream of gas flow. In many cases, an electrostatic precipitator can be operated with up to 99% efficiency with a wide variety of operating conditions. As new clean air regulations take effect and utilities strive to improve efficiency and performance, few products can be as cost effective as PECO-FGC’s CFD (Computational Fluid Dynamics) Modeling. CFD Modeling takes into consideration the several different variables including; temperature, flow, gas distribution throughout the precipitator (from inlet to outlet), as well as flyash collection trends on plates, in ductwork, in the hoppers, and reintrainment throughout. Having the ability to model the exact gas flow and temperatures of an existing precipitator can help provide solutions for ESP retrofits and improvements. By combining computational and experimental modeling to predict fluid behavior in new and existing ESP installations, flow problems can be found, analyzed and prevented. Corrective flow devices such as turning vanes, or variable porosity perforated plates can then be modeled, designed, tested and installed to ensure that flow characteristics meet the desired results of each application.
