COAL POWER Direct

Certain small utilities with some of the nation’s highest carbon dioxide emission rates want to change the climate bill pending before Congress to give themselves more allowances to emit carbon dioxide (CO₂). This would be the ultimate “cash for clunkers” program for dirty power plants, with one key difference: Unlike the real program, in this case the clunkers would get to stay on the road. The Senate should reject this change.

The commentary "No ‘Cash for Clunkers’ in Climate Bill" creates a fictitious history of climate change and seriously harms good faith efforts within the industry to address the legitimate issues many utilities have raised with the Waxman-Markey bill.

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.

Environmental researchers from Harvard and Tsinghua Universities released a new study, published as the cover story in the September 11 issue of Science, suggesting that China could meet its entire future electricity needs through wind power alone. Studies that focus on a single technology as the silver bullet that solves all of our energy problems often ignore the practical side of their solutions, leaving mistaken impressions in the public mind.
