A new optimizer tool for wet electrostatic precipitators

| By Mary Page Bailey and Gerald Ondrey

This company has launched a digital optimizer for the Editube wet electrostatic precipitator (WESP). The new WESP Optimizer improves the operation of the WESP unit by better adjusting it to changes in the overall process, and has important built-in functions to protect units with plastic tube bundles (photo) during low acid-load operation, as well as during startup and commissioning. In addition, the Optimizer increases removal efficiency during high acid-load operation, and provides energy savings whenever there is spare capacity. The Optimizer also monitors the behavior of each WESP, enabling faster damage detection, and provides operators with otherwise unavailable information, such as calculated removal efficiency, says the company. The WESP optimizer continuously monitors the process conditions and provides a combination of automatic optimization of transformer rectifier (T/R) unit parameters, information and suggested actions for operators. — Metso Outotec Oy, Helsinki, Finland
