World leaders have begun arriving in Copenhagen days before the international conference’s close on Dec. 18 to sign a comprehensive pact to curb climate change, but disagreements—mostly on rich-poor lines—among the 193 attending nations on issues from emissions reductions to technologies such as carbon capture and storage (CCS) could mean there may be nothing to sign.

Sen. Lisa Murkowski (R-Alaska) on Monday said she would file a disapproval resolution to stop the Environmental Protection Agency (EPA) from regulating greenhouse gas emissions (GHG) under the Clean Air Act.

By Kennedy Maize Having just returned from three weeks of vacation, where I paid no attention to power issues, here are some items I’ve discovered since my return. I hope my take will spark some conversations. First, “Climategate.” This flap of major proportions, threatening to unravel the alleged scientific consensus behind global warming, blew up […]

The U.S. Environmental Protection Agency has adopted final rules tightening emissions limits for coal preparation and processing plants and imposing new reporting requirements on those facilities.

In a major air regulatory development, the Environmental Protection Agency has agreed to issue rules by November 2011 to reduce mercury and other hazardous air pollution from coal- and oil-fired power plants under a settlement agreement resolving a lawsuit filed by a host of environmental organizations.

The Environmental Protection Agency has decided it will reconsider the 2008 ozone standards issued by the Bush administration, with the agency suggesting in a court that it would toughen the standards because it has concerns about whether standards “satisfy the requirements of the Clean Air Act.”

There are four approaches to measuring fly ash content and, therefore, the quality of fuel combustion in a boiler. Before choosing one, you should understand their relative levels of complexity and accuracy.

Erosion can significantly reduce the operational life of boiler components. Abrasion-resistant ceramic parts can be a sound alternative to expensive metallic parts when replacing boiler components.

If the basic science related to man’s contribution to a warming planet is based on flawed fundamental science, a conscious circumventing of the peer review process, political expediency, and refusing to release the fundamental data used by a computer program that has yet to replicate actual ambient temperatures, then it’s time to pause, take a breath, and regroup.

When the Łagisza power plant began commercial operation in late June 2009, it marked the beginning of a new era in the evolution of circulating fluidized bed (CFB) technology. At the heart of this 460-MW plant is the world’s largest CFB boiler, which is also the world’s first once-through unit supercritical CFB boiler.
