W. R. Grace: Plant Uses Six Sigma Methodology and Traditional Heat Balance Analysis to Identify Energy Conservation Opportunities at Curtis Bay Works (Revised)

The plant-wide energy assessment at W. R. Grace's Curtis Bay Works helped identify four projects with combined potential savings of $840,000 per year. A separate, unique project that would partner W. R. Grace with the City of Baltimore to recover and use landfill gas (methane) to cogenerate steam and electricity was also identified during the assessment. If implemented, the project would recover gas from the landfill to replace 40% of the electricity and 65% of the fuel currently required to produce steam at Curtis Bay Works. Annual savings are estimated at $900,000 to $1.2 million.

Weirton Steel: Mill Identifies $1.4 Million in Annual Savings Following Plant-Wide Energy-Efficiency Assessment

The Weirton Steel Corporation performed a plant-wide energy assessment of its steel mill plant in Weirton, West Virginia. Based on the assessment results, the company found strong economic justification for six projects that would reduce the use of fossil fuel, electrical energy, and water. All of the projects would save fossil fuel either for heating steam or firing the furnace. This savings totals 108,300 million British thermal units (MMBtu) annually or $1.27 million. Other yearly savings include 119 million gallons of water ($87,110) and 84,000 kilowatt-hours (kWh) or $3,357 of electrical energy. All of the projects could be applied to other steel mills and possibly other industries using steam processes and furnaces.

Boiler Blowdown Heat Recovery Project Reduces Steam System Energy Losses at Augusta Newsprint (open access)

Boiler Blowdown Heat Recovery Project Reduces Steam System Energy Losses at Augusta Newsprint

The boiler blowdown process involves the periodic or continuous removal of water from a boiler to remove accumulated dissolved solids and/or sludges. During the process, water is discharged from the boiler to avoid the negative impacts of dissolved solids or impurities on boiler efficiency and maintenance. However, boiler blowdown wastes energy because the blown down liquid is at about the same temperature as the steam produced. Much of this heat can be recovered by routing the blown down liquid through a heat exchanger that preheats the boiler's makeup water. A boiler blowdown heat recovery project at Augusta Newsprint Company's Augusta, GA mill will save almost $31,000 annually in fuel costs.
