Maintaining Nuclear Plant Ice Condensers: A ‘Cool’ Responsibility

Although nuclear plant ice condensers are rare—only seven sites throughout the world have them—the theory behind these passive heat sinks is quite novel. In fact, some next-generation plant designers have built upon the concept and incorporated passive accident intervention schemes into their plans. A nuclear plant ice condenser is a passive, static heat sink that […]

Building the Case for Power System Hardening

Purse-string holders are pretty easily swayed to approve funding to upgrade transmission and distribution systems following major events like Superstorm Sandy and Hurricane Irene. However, it is becoming

MPW’s Improvements Lead to Savings for Southeastern Pulp and Paper Facility

Problem
A Florida pulp and paper mill faced a complicated, dangerous process to clean its power boiler during scheduled outages.
Previous efforts to clean the boiler included manual water blasting from scaffolding, which posed a safety risk to workers below due to the potential for falling debris.
Solution
The Operations team at MPW Industrial Services recommended that the facility’s

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 […]
