Republicans picked up more than enough seats during the mid-term elections to assume control of the House, but don’t expect any relief from the administration’s war on coal-fired power plants.

Boiler auxiliary equipment often receives no respect for the role it plays in maintaining efficient boiler performance. In this second installment of our Power 101 series, we examine the design and performance of the air preheater.

A long-awaited Clean Air Act regulatory guidance document released by the Environmental Protection Agency recommends that state air regulators strongly emphasize energy efficiency in determining the most cost-effective and technically feasible greenhouse gas control technologies that must be used by utilities and other major industrial emitters when expanding existing facilities or building new ones.

With utilities already alarmed by looming federal regulations that could force construction of expensive cooling towers that would sharply increase water use, a report by the Energy Department’s Argonne National Laboratory warns that nearly 350 U.S. coal-fired power plants are vulnerable to potential water demand or supply conflicts over the next 20 years stemming from increased competition for dwindling water resources—particularly in the Southeast.

While U.S. coal production has been stagnant in 2010, demand for coal in China and India has sharply risen this year and could represent the early stages of a "long-term supercycle" for the global coal industry, according to Peabody Energy, the world’s largest private coal company.

Combustion flue gas analysis has been used to optimize the boiler air/fuel ratio for decades. Measuring the amount of excess oxygen and/or carbon monoxide in combustion flue gases gives an indication of boiler efficiency and, thereby, plant operating economics. New sensors make those measurements simple and accurate.

Energy efficient and environmentally responsible dry bottom ash technologies will soon be required by regulation. Progressive companies will bring their plants into compliance early because it’s a good business strategy. Here are your compliance options.

The Environmental Protection Agency (EPA) last week issued a long-awaited document that provides policy guidance to state agencies on how to start issuing permits to power plants and other stationary sources of greenhouse gases (GHG) when the rules take effect on Jan. 2. The document also provides technical information on how to implement the “Best Available Control Technology” (BACT) requirement for GHG sources applying to Prevention of Significant Deterioration (PSD) permits under the Clean Air Act—though it stops short of prescribing BACTs.

FirstEnergy Corp. today announced it would permanently shut down units 4 and 5 at its R.E. Burger Plant in Shadyside, Ohio, by Dec. 31, abandoning plans to repower the coal units with biomass. The Akron-based company cited a significant plunge in market prices of electricity, saying that they “no longer support a repowered Burger Plant.”

The UK’s Department of Energy and Climate Change (DECC) on Thursday approved a 900-MW combined cycle gas turbine (CCGT) power station in Spalding, Lincolnshire, in an effort to boost the nation’s energy security. The consent was given on the condition that the plant reserves enough space to allow for a future retrofit of carbon capture technology.
