Of nearly 18 GW of U.S. generating capacity permanently shuttered in 2015, 77% was conventional steam coal–fired. About 30% of that 13.7 GW in coal capacity was retired in April 2015, when the Environmental Protection Agency’s (EPA’s) Mercury and Air Toxics Standards (MATS) rule went into effect, said the Energy Information Administration (EIA) on March […]

China has been struggling for years with endemic air pollution in major cities like Shanghai, and the nation’s traditional heavy reliance on coal has been challenged head-on by new government policies to cut emissions and reduce the carbon intensity of the power sector. While major advanced coal plants and China’s massive build-out of its nuclear […]

MPW’s Bundle Blaster Side Cleaner system is designed to remotely clean the shell side of small to medium
sized tube bundles, up to 36 feet in length. The tube bundle is placed on hydraulically actuated rollers to
incrementally turn the bundle during the cleaning process while the cleaning head runs horizontally on a track
over the bundle. MPW’s

Entergy Corp. announced on March 4 that three of its subsidiaries had closed on a transaction to purchase the 1,980-MW Union Power Station near El Dorado, Ark. The plant includes four combined cycle gas turbine (CCGT) units, each rated at 495 MW. Each unit operates two GE 7-FA combustion turbines with inlet air fogging, two […]

The fleet of Siemens H-class high-efficiency gas turbines achieved more than 200,000 operating hours in January 2016. There are currently 19 turbines in the SGT-8000H series in commercial operation, and they are setting the standard for efficiency, reliability, and availability. Siemens has sold a total of 76 H-class gas turbines worldwide to date: This makes […]

Steam turbines have to be warmed slowly to avoid excessive differential expansion of the various components, rotor stress, and potentially reduced service life. For that reason, startup times must be extended

Gas power technologies set new benchmarks over the past few months as gas turbine “gorillas” Siemens, General Electric (GE), and Mitsubishi Hitachi Power Systems Americas (MHPSA) all reported new

At the ballyhooed Paris climate conference last December, a little-noticed event occurred that could lead to important developments for electric generators. At the Paris meeting, some 80

Germany’s Energiewende (energy transition) was adopted as policy beginning in September 2010, some six months before the disaster at Japan’s Fukushima nuclear plant, and full legislative support was

Many combined cycle and cogeneration plants with heat recovery steam generators (HRSGs) were originally intended as baseload power sources or steam producers. In recent years, however, some have been
