COAL POWER Direct

The Obama administration often says that there is room for coal in our future fuels mix. However, the administration’s actions lead me to believe President Obama has something much more profound in mind.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of this three-part report, we introduced the A-USC boiler. In this segment, we look at the metallurgical advancements required for the A-USC boiler to operate at such high temperatures. The final report will explore the A-USC boiler’s unique design challenges.

This unconventional technique for removing slag from solid fuel-fired boilers, used for more than two decades, has exploded in popularity. But the risks are very real, and not all blasters are created equal.

Moving into the election season, President Obama has again pointed to the number of green jobs supposedly created by his administration in a recent campaign advertisement, although the claims are not supported by available data. Now, other government authorities are using the same poor data as an excuse to increase spending.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of a three-part report, we introduce the A-USC boiler. Future reports will discuss the metallurgical and boiler design challenges.

What killed global warming as the president’s number one priority?

Freedom, opportunity, prosperity, and a civil society have made America exceptional. But without energy—secure and affordable energy—many of our great accomplishments would not have been possible.

FirstEnergy Corp., AEP, and GenOn have all announced coal-fired plant closures, totaling over 13 GW, caused by the recently finalized Mercury and Air Toxics Standards.

A proposed rule issued in late February by the Environmental Protection Agency (EPA) will not change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs. However, it includes revisions to the permitting program that would provide some flexibility in how compliance is achieved with GHG emission caps.

A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered over North America. Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes.
