There may be multiple closed-loop cooling systems at your power plant. Chances are good that they cool or control temperature on some very critical components. The two that are most likely to exist are the

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

Case Study: MPW’s Automation Simplifies RO Replacement Process for Indiana Energy Plant

INDUSTRIAL WATERMPW’s emergency response pays off for Virginia Challenge:
When a Virginia power station had an issue with its existing Reverse Osmosis [RO] process, it called on MPW to supplement its water needs during an excessively cold winter.
The plant lost RO functionality at one of its four power-production units, which would severely damage its ability to

The identification and containment of coal ash has risen to the top of the priority list for plant managers across the U.S. after inadvertent releases of coal ash into unintended areas resulted in adverse

Drax Power Station, a 3,960-MW six-unit facility located in North Yorkshire, England, is the largest power plant in the UK. It was constructed in two stages, with the first three units completed in 1974 and

When we undertook an initiative at Granite Ridge Energy (GRE) to identify, prioritize, and assess components that were due for their 10-year assessments, we didn’t know quite what we were taking on or how to

The historic winter storm that buried the Eastern U.S. in snow over the weekend shut the lights off for more than a million customers from Arkansas to Massachusetts as it downed power lines and hampered operations at some power plants. According to the Department of Energy’s Office of Electricity Delivery and Energy Reliability, at one […]

Grid resiliency has become a widely discussed topic recently. Experts have been called before congressional hearings to testify on the topic, and close calls—including a massive solar storm that missed Earth

The Electric Power Research Institute (EPRI), in conjunction with Suprock Technologies, has conducted a research project to develop and demonstrate an advanced wireless sensor technology for monitoring torque

It is true that electric motors and transformers are some of the most dependable pieces of equipment installed at power plants. They can, in many cases, withstand a high level of mistreatment while continuing

Gas-fired power is booming—even more than expected. For only the second time ever, but also the second time this year, gas generated more electricity in a month in the U.S. than coal. According to statistics

Coal pulverizers are the heart of a pulverized coal-fueled boiler. Often, the root causes of nonoptimized combustion lie with the pulverizers. Capacity; reliability; and environmental issues such as slagging

Two hyperbolic cooling towers rise 495 feet over Exelon Corp.’s Byron Generating Station about 110 miles west of Chicago, Ill. The towers help cool the two Westinghouse pressurized water reactors that are capable of generating up to 2,346 MW at the site. Like all classic wet transfer hyperbolic cooling towers (Figure 1), the Byron Generating […]

Some critters may be cute, but when jellyfish gum up power plant cooling systems; birds, rats, snakes, or squirrels cause electrical shorts; or invasive mollusk species obstruct hydropower plant pipes, losses can be steep. Here’s how some power plant operators are dealing with their critter troubles. There are countless cases of wildlife entering power plant […]

As many coal-fired power plants designed for baseload service are asked to cycle, unforeseen stresses have been introduced to boiler pressure parts. Understanding the effects and implementing mitigation strategies could prevent premature component failure and keep facilities operating reliably. On August 3, 2015, the U.S. Environmental Protection Agency finalized the Clean Power Plan, which calls […]

Creeped out and fatigued—that’s the state of many coal-fired boilers these days. Understanding failure mechanisms and suitable testing methods for identifying potential trouble can help you find problems before the problems find you. Even as the current regulatory environment pushes new power generation to utilize natural gas over other fuel sources, a significant amount of […]

Coal dust combustion events injured employees and damaged equipment at Laramie River Station in May 2013. Any dust-filled facility could consider implementing some of the plant’s corrective actions to reduce the risk of experiencing a similar incident. When Laramie River Station (LRS), near Wheatland, Wyo., was built nearly 35 years ago, it was state-of-the-art. Constructed […]

Entergy Corp.’s Palisades Power Plant returned to service on Oct. 19, following a month-long outage to implement upgrades, inspections, and safety enhancements.  The Michigan plant was shut down on Sept. 16 to begin a planned refueling outage. The company spent $58 million for upgrades and plant inspections, and $63 million for new fuel. The outage […]

Replacing blades on a wind turbine is not a simple task. Blades range from 40 to 60 meters in length and can weigh 16 tons or more. Combined with hub heights that can exceed 100 meters and locations that are, by definition, subject to prevailing winds, replacing blades becomes challenging. Add in the cost of […]

Shaft collars are used as stops or locators on shafts in a wide variety of applications. There are two basic types. One uses a setscrew to lock the collar in place, while the other utilizes a clamp-type collar. Shaft Collar Designs Setscrew collars are the oldest type of shaft collar. These units function by gouging […]

In presentations to the Federal Energy Regulatory Commission (FERC), the nation’s regional transmission organizations (RTOs) and independent system operators (ISOs) on Sept. 17 outlined measures they are taking to prevent issues if faced with extreme weather this winter.  The measures are to prevent widespread generation outages as occurred during the Jan. 6–7, 2014, polar vortex. […]

Duke Energy Indiana reached a settlement agreement with some of the state’s key consumer groups related to operating costs at its Edwardsport integrated gasification combined cycle (IGCC) coal power plant. The deal was submitted to state regulators on Sept. 18 and is subject to Indiana Utility Regulatory Commission (IURC) approval. If approved, it would resolve […]

Exelon has optimized the efficiency of its operations, maintenance, and engineering staff. By automating data collection, plant engineers now focus on analyzing data rather than manually collecting data and risking radiation exposure. Download this case study to get more details then go here to learn more about Condition Based Maintenance (CBM) for Power Generation.

In today’s digital world, an optimally run power plant relies on valuable and accurate data in order to ensure assets are running reliably and with minimal downtime. Streaming in from control systems, SCADA

There is a synergistic relationship among the three major cooling water treatment issues: corrosion, scale or deposit formation, and microbiological fouling. In order to control one, you need to control all

While having lunch at a downtown café with my friend the biology professor, the subject of animal extinction arose. “When it comes down to it, we really don’t know exactly why most prehistoric species

The power generation industry is undergoing a period of rapid transformation. A growing number of operators are considering the adoption of condition-based maintenance (CBM).  This whitepaper discusses the forces that are driving demand for CBM, how CBM works and why it is an effective alternative to planned maintenance strategies.

U.S. wind power is becoming more widespread and costs are generally on the decline, but the sector is troubled by policy uncertainties, a new report from the Energy Department says.   After a lackluster year in 2013, wind power capacity additions in the U.S. rebounded nearly 8% in 2014, driven by recent improvements in the […]

I’ve got some good news and some bad news. The good news is that, according to the U.S. Bureau of Labor Statistics, the number of occupational fatalities resulting from exposure to electricity has decreased steadily during the past 10 years (Figure 1). The bad news is that 141 people died on the job in the […]
