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: 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 […]

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 […]

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). Units 1 and 2, each with a nominal rating of 600 MW, are co-owned by the Lower Colorado River Authority (LCRA) and Austin Energy (AE). LCRA is a conservation and […]

The Coal Patrol: Coal-to-Liquids Resurfaces after 20 Years

It’s déjà synfuels all over again. With crude oil prices seemingly interminably pegged at over $60 a barrel, the old, beguiling notion of turning coal into liquid fuel — a task accomplished by the Nazis in the 1940s and the South Africans in the 1970s and 1980s — is once again front-page political news in […]

Speaking of Coal Power: Illinois Coal Poised for Comeback

Sylvester Stallone, as Rocky Balboa, staged another magical comeback earlier this year — in the ring and at the box office. Just when you think Rocky is down and out for good, the sixth release of the Rocky franchise just may be the best of the lot. "Down but not out" is also an apt […]

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 […]

At CERA Week 2007, most life was carbon-based

For the past 25 years, Cambridge Energy Research Associates has hosted an annual conference that has drawn the captains of the worldwide oil and gas and electricity industries. The 120 distinguished speakers at this year’s summit attracted more than 2,000 delegates from 55 countries, making it the largest and most diverse ever. Naturally, one of POWER’s contributing editors was there, too; here’s his take on what transpired.

Exploring the many carbon capture options

Carbon capture and sequestration have many technical hurdles to leap in coming years. The capture and reuse of CO2 to enhance oil recovery preceded the current clamor over climate change, and that experience is often used as an example that the process is a viable way to handle this greenhouse gas. This article explores options for the first part of the process: CO2 separation and capture.
