Three U.S. Nuclear Plants Get Poor Marks from NRC

Officials with the U.S. Nuclear Regulatory Commission (NRC) plan to hold a public hearing May 31 on the safety record of the Arkansas Nuclear One power plant in Arkansas, whose two units are among three cited by the agency for poor performance and other problems in its annual assessment of the nation’s nuclear fleet. The […]

MPW Mobile Ultrafiltration and Demineralization Units Exceed Canadian Power Plant Expectations

Challenge:
After a major refurbishment, a Canadian nuclear plant required additional process and boiler feed water for plant start-up and commissioning.
The plant’s raw water supply contained measurements ranging from 1-10 NTU, conductivity from 70-100 and color units ranging from 180-420. The plant also experienced highly variable flow rates, ranging from 0-600 GPM, and issues with the

Wind Power Faces a Post-PTC ‘Valley of Death’

Wind power capacity in the U.S., whose explosive growth has tripled since 2008—even overtaking hydropower to become the nation’s largest source of renewable electricity—could face a period of stagnation once the production tax credit (PTC) is phased out in 2021. Analysts at WINDPOWER 2018 in Chicago last week called the period between 2021 and 2026 […]

The engine room of the Falk Co. power plant in Milwaukee, Wis., included a 550-kW main generator and a 125-kW auxiliary generator, both driven by Allis-Chalmers horizontal cross-compound Corliss engines.

From the Pages of POWER Magazine: #TBT #ThrowbackThursdays

In early 1882, U.S. industry was still heavily dependent on the water wheel, and many housewives cooked on wood-burning stoves. Power was made where it was used because there was no effective means of transmitting energy long distances. But 1882 was a year of dramatic changes. The world was just beginning to grasp the implications of a new, incredibly versatile […]

The Best Place to Sample HRSG Tubes

Finding the best place to sample heat recovery steam generator (HRSG) tubes isn’t as hard as finding a needle in a haystack (but it’s like that). Ask most HRSG users where they take their routine tube samples for monitoring under-deposit corrosion in the high-pressure evaporator, and they’ll tell you, “first row, because it’s the hottest […]

The Siemens SGT-800 industrial gas turbine combines a reliable robust design with high efficiency and low emissions.

GE Sets Sights on MHPS and Siemens Customers

Drawing on decades of gas turbine experience, GE’s Power Services business announced on May 16 that it is expanding its cross-fleet service offerings to a broader portion of the F-class market, including Siemens’ SGT6-5000F and SGT-800 models, and Mitsubishi Hitachi Power Systems’ (MHPS’s) 501F technology. “GE is proven as one of the technology leaders and […]

Basics of Sound and Noise Propagation

According to the Occupational Safety and Health Administration, 22 million people—including nearly all power plant workers—are exposed to potentially damaging noise at work each year in the U.S. Hearing

Egyptian Ethylene and Derivatives Co. (ETHYDCO) was determined to implement a process for water recycling and reuse, enabling water to reach ZLD by applying the most modern technology to meet compliance.

Bringing New Life to Industrial Wastewater

As water demand soars in every corner of the world amid widespread drought and water scarcity concerns, recovery and recycling of wastewater is increasingly becoming a valuable solution to alleviate pressures
