Power Plant Conversion

PacifiCorp-Hunter-PJFF

Power Plant Conversion may be the best solution for plant operators

There is a growing trend in the utility industry to convert existing coal-fired power plants to burn other fuel types, such as biomass and natural gas. Conversion is being driven by a number of factors, including renewable portfolio standards; federal incentives and looming environmental regulations; consumer demand and environmental awareness. These factors combined with a new economic climate are making coal less attractive. Although conversion costs can be expensive, utilities already have the facilities sited and water supply and transmission lines established. Converting existing facilities can often cost less than installing the emissions control systems required to keep an antiquated coal plant running.

NADC has compiled a portfolio of major power plant conversions. This experience can be beneficial to those facilities that want to convert rather than dismantle or demolish power plants. Contact us for more information.

The following project highlights these capabilities:

PacifiCorp Energy – Hunter & Huntington Power Plants
Electrostatic Precipitator Conversion to Pulse Jet Fabric Filter (PJFF) Technology

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.
Work Performed: dismantling, high lift and crane rigging

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.
