Engineering Study & Feasibility Analysis

Fruit of the Loom Steam Facility

Evaluation of Existing Wood-Fired Boiler System

Owner: Fruit of the Loom

Project Location: Rabun Gap, Georgia

Project Completion: February 2003

Project Description:

ESI performed an engineering study and economic feasibility analysis for Fruit of the Loom to perform an assessment of the existing wood-fired boiler system and make recommendations for capital improvements to allow continued operation for 10 to 20 years. This study included a cost estimate to upgrade the existing wood-fired boiler system with: new electrostatic precipitator (to replace failing scrubber system) and ID fan, SNCR system, upgrades for overfire air system to improve efficiency and reduce emissions, modifications to existing fuel delivery, and upgrade of existing control system. The economic analysis was performed to evaluate the viability of upgrading the existing system versus installation of a new natural gas boiler system. The economic proforma analyzed capital cost for both systems along with annual maintenance, fuel, ash disposal, personnel, parasitic power, depreciation, insurance and tax costs. The study included recommendations for both short-term continued operation as well as long-term capital improvements for safety, reliability, efficiency, and environmental compliance.
