Electrostatic Precipitator Conversion

Electrostatic Precipitator Conversion to
Pulse Jet Fabric Filter (PJFF) Technology

Work Performed: dismantling, high lift and crane rigging

Project Description

This project was a fast track conversion of an existing electrostatic precipitator (ESP) to Pulse Jet Fabric Filter (PJFF) technology. Casey Industrial was PacifiCorp’s chosen design building contractor for this project. Project specs were identical for both the Hunter Power Plant Unit 2 and the Huntington Power Plant Unit 1..

The projects took place during the Owner’s planned outage in September of 2010. Notwithstanding, North American Dismantling Corp. (NADC) worked hand in hand with Casey to develop an execution plan months in advance of the outage date.

This execution plan included Casey engineering and installing a 4600 Manitowoc ringer crane as the main hoisting device for the project. In addition, Casey assisted the Owner in planning and executing an environmental “sweep” of the ESP at the inception of the shutdown. This allowed for a fluid transfer of the precipitator to Casey and its’ subcontractors.

NADC was mobilized and ready to begin operations as was originally specified. The ringer crane was used to stage demolition equipment on the precipitator as it was turned over. Cut lines were identified and laid out to confirm as built conditions. NADC then began its dismantlement operations.

The existing roof mounted transformers/rectifiers were dismantled and hoisted from the roof. The bulk of the ESP was removed in large components (80,000 lbs.) or “bundles”. This was unique and essential because the new PJFF would utilize the existing hoppers, structure, interior bracing and center dividing structure.

To insure the safety of traffic traveling along the roadway, NADC provided the necessary road/landing area security during the course of its operations. The project was completed without incident or OHSA recordable accidents.
