  • PRB Tech Notes: Pay Me Now or Pay Me Later

    Money is always spent with the best intentions. We look for the best deal, often identifying it by the lowest price. Sometimes, our choice works out and we save money and get a great product. When it doesn’t work out, however, we find ourselves spending more and more money to repair or replace our “great […]

  • Coal Plant O&M: River Locks and Barges Are an Aging Workforce, Too

    During 2005, about 150 million tons of coal were transported to power plants by hopper barges plying U.S. inland waterways. With coal-fired plants expected to continue producing 50% of America’s electricity, coal barge traffic is not likely to fall off. In fact, it may increase, for two reasons. One is cost. Shipping coal by barge […]

  • Pollution Control: LCRA Fayette Lowers NOx Below 0.10 lb/mmBtu

    The Fayette Power Project (FPP, aka the Sam K. Seymour Power Station) is a three-unit, coal-fired generating plant sited near La Grange, Texas (Figure 1).

  • Pollution Control: Low-NOx Combustion Retrofit Options

    Reducing NOx emissions from large utility coal-fired boilers has been a primary focus of the U.S. power generation industry since passage of the 1970 Clean Air Act and subsequent legislation. By the early 1990s, nearly all such boilers had installed some form of low-NOx burner (LNB) technology and/or overfire air (OFA) — the least expensive […]

  • The Coal Pile

    Ninety years ago America was at war, and producers of coal (principally anthracite) were struggling to meet demand. It’s hard now to conceive of coal as the universal fuel, but there was a time when it was used in the U.S. to heat homes, schools, and libraries as well as to make steel and manufacture […]

  • Nuclear ambitions

    Ten years ago, any self-respecting U.S. utility executive might have been drawn and quartered for publicly promoting a nuclear power revival. How times have changed. Today, more than half of America’s nuclear plants have outsourced their operations to specialty firms, and the prospect of a nuclear renaissance in the U.S. (see Cover Story) is brighter […]

  • Full-service utilities prove their value

    During the past year, the debate over the structure of the nation’s electricity systems has continued at a steady clip. It seems that almost every month a new study or report is issued that proclaims the advantages or disadvantages of one market structure over another. Although a report or study may have value, the Community […]
