Boiler Conversion: Converting a Boiler from Burning Bituminous Coals to PRB Coals Can Be a Challenge
Design techniques and operating experience with Powder River Basin (PRB) coals have advanced significantly over the past 35 years for boilers that were originally designed for this fuel. Today, boiler installations looking to effectively utilize PRB coals fall into two primary categories: units that were initially designed for bituminous or other coals and units that […]

Case Histories: Co-Firing Coal and Oat Hulls Reduces Emissions at University Power Plant
The University of Iowa (UI) Biomass Fuel Project has produced significant reductions in greenhouse gas emissions, regulated boiler stack emissions, and purchased energy costs. The project utilizes a renewable, biomass fuel source and provides an opportunity for UI to partner with a local industry. UI was approached by Quaker Oats Co., Cedar Rapids Facility in […]

Case Histories: Asheville Power Station’s Retrofit First to Meet North Carolina’s Clean Smokestacks Act
Asheville Power Station’s Unit 1 in Arden, North Carolina, was the first coal-fired unit to be modified with a flue gas desulphurization (FGD) system and placed in service to meet the clean air requirements of the state’s Clean Smokestacks Act. As of November 16, 2005, at least 97% of the sulfur dioxide that had been […]

Case Histories: Synthetic Oil and Enhanced Filtration Reduce Wear and Extend Gear Life
A coal-fired power plant operating in the western U.S. was experiencing short gearbox life in its coal-pulverizing operation. After an annual gearbox inspection, oil analysis results indicated that the AGMA 6EP (ISO 320) gear oil recommended by the original equipment manufacturer (OEM) had failed to provide adequate lubrication and protection. This conclusion was based on […]

Coal Users Community: Growth Is the Byword for Gasification
The Gasification Technologies Council (GTC, www.gasification.org) was created in 1995 with a straightforward mission: to promote the greater use of gasification as an environmentally and economically preferred alternative for the production of power, fuels, and chemicals from low-value energy sources. Those energy sources include high-sulfur coal, petroleum coke, and wastes. Since that time the GTC […]

Currant Creek Power Plant, Mona, Utah
Commercial operation of PacifiCorp’s first new power plant in more than 20 years coincided with the company’s acquisition by MidAmerican Energy Holdings Company this past March. Currant Creek treads lightly on the environment, provides needed power to PacifiCorp’s eastern control area, and has demonstrated its commitment to be a good corporate citizen of the local community. By any account, Currant Creek is a model for how to develop a power project.

Monticello Steam Electric Station, Mount Pleasant, Texas
Why does Monticello, a 30-year-old plant, deserve recognition as one of POWER’s Top Plants of 2006? Because TXU has been blending Powder River Basin (PRB) coal with local lignite at the plant for the past decade, and steady reductions in air-pollutant emission rates have been the result. That positive experience has made the company confident enough to propose building nearly 9,100 MW of new coal- or lignite-fired capacity in Texas by 2010 at a cost of $10 billion. Read on to share some of the lessons that TXU has learned about handling PRB coal safely.

Coal: The cornerstone of America’s energy future
In April 2005, U.S. Secretary of Energy Samuel W. Bodman asked the National Coal Council to develop a “report identifying the challenges and opportunities of more fully exploring our domestic coal resources to meet the nation’s future energy needs.” The council has responded with eight specific recommendations for developing and implementing advanced coal processing and combustion technologies to satisfy our unquenchable thirst for energy.
