The coal-fired power generation industry is in the midst of uncertainty. In February, the U.S. Environmental Protection Agency issued final Clean Air Act standards for boilers and other equipment.
Due to the uncertainty over future carbon dioxide emissions regulations, many power companies are turning to combined-cycle power technology for future generation. Of course, the combustion turbine is the key component of a combined-cycle plant, but so are the heat recovery steam generator (HRSG) and steam turbine.
In 2010, the U.S. Department of Energy’s National Energy Technology Laboratory (NETL) sponsored demonstration projects to reduce CO2/MWh using generation efficiency improvements through combustion balancing at two coal-fired power plants1.
In Stephen King’s 1994 made-for-TV movie “The Stand,” most of the human race is wiped out by a deadly virus. As a result, power stations are unmanned and Americans are left without electricity for months.
Faced with competitive pressures to cut costs and reduce carbon emissions, owners and operators of industrial and commercial facilities are actively looking for ways to use energy more efficiently. As electrical prices rose in recent years, the allure of combined heat and power (CHP) grabbed many people’s attention.
The most-up-to date discussions of what is happening in the coal-fired power generation industry will take place when the 11th annual Coal-Gen conference and exhibition gets underway in Columbus, Ohio beginning Aug. 17 and running through Aug. 19.
Over the last 10 years, much time and money has gone into the development of numerous carbon capture technologies, as well as the study of the costs and impacts of utilizing these technologies. Many owners would like their plants to be “capture ready,” or would like to know what it would take to make them capture ready.
Thank you for your “After Japan” editorial in the April issue of Power Engineering. As a Ph.D. nuclear engineer, I could not agree more with your opinion that Japan’s nuclear crisis should not end the era of commercial nuclear power generation.
New nuclear’s future may depend less on what happened at the Fukushima Daiichi nuclear power station in Japan than what is happening at two construction sites in Europe.
In March 2011, the Environmental Protection Agency released with much fanfare a guidance document to provide “the basic information that permit writers and applicants need to address greenhouse gas (GHG) emissions in permits.”
Electric utility companies are installing digital electronic devices and communications gear to make the nation’s electric grid “smarter.” These efforts include deploying advanced relaying and automated monitoring systems to make the grid more reliable and creating technology-based partnerships with other innovators to help customers better manage their energy use.
Developers of small modular reactors (SMRs) have got to be cursing their bad luck. Just when they were building some momentum in their efforts to break into the big leagues, Fukushima Daiichi threatens to cancel their baseball season for who knows how many years...or has it?
Combined heat and power (CHP) plants account for 84 GW of capacity and the Department of Energy has set a goal to increase that to 241 GW by 2030. If met, CHP will provide 20 percent of U.S. power generation. Since 2005, nearly 4 GW of combined heat and power capacity has been retired and around 1 GW a year has been added.
While billions of dollars are being invested in promoting clean energy, coal is still the reliable workhorse of power generation worldwide. Coal gassification or carbon capture technologies may provide cleaner power at some point in the future, but for right now utilities are increasingly turning to dry scrubbers as a way to meet toughening emissions standards.
ABB has announced the launch of its Symphony Plus distributed control system (DCS). Key customer benefits include improved plant productivity and energy efficiency, as well as enhanced operational security, plant safety and a lower total cost of ownership.
Seems Thomas Edison may have been something of an architect and building materials guy, too.
