Green Strategies for Aging Coal Plants: Alternatives, Risks & Benefits
There are quite a few power stations less than 400 MW in size with successful and long histories of operation.
Properly Monitor Your Scrubber Chemistry
Within the last several years the flue gas desulfurization (FGD) market has mushroomed and many utilities have purchased and are erecting wet FGD systems.
Zero-sum Game?
Water issues are becoming a huge factor in U.S. economic development activities and the power generation industry is feeling the effects.
Putting a Stop to the Stop-and-Go
Stopping and starting is expensive. Cars last longer and get better mileage with freeway rather than city driving.
A New Coal Blending System for AES Cayuga
A The AES Cayuga Plant (previously New York State Electric and Gas’ Milliken Station) stands along the shore of Lake Cayuga in New York State.
Benchmark Globally, Improve Plant Performance Locally
Since the 1970’s, the World Energy Council Performance of Generating Plant committee (WEC PGP) has collected power plant performance statistics from various countries with the goal of identifying means to collect/disseminate data as well as means for evaluating performance and identifying performance opportunities.
Export Markets for U.S. Clean Coal Technology
Larry Hunt knows the coal mining business as well as anybody. After all, he came from an Eastern Kentucky coal mining family, first working the mines with his father in 1962.
Clearing Weather at Mt. Storm
A fuel change clouded the outlook at Dominion’s Mt. Storm station, but changing the feeders and delivery system to mass flow improved the forecast.
Why Alignment?
Proper shaft alignment of directly coupled machines has proven to be one of the greatest money savers for machinery-intensive industries over the last 25 years.
Boiler Optimization and SCR Systems: Reducing NOX, Managing Tradeoffs
For nearly five years, two selective catalytic reduction (SCR) systems have operated almost around the clock at Dynegy Midwest Generation’s Baldwin Energy Complex in Baldwin, Ill.
O&M Notebook: Leak Reduction Programs
Many sites, nuclear and fossil, lack a program and subject matter expert for fluid sealing.
Central Solar Power for the Southwest
As utilities in the United States seek to develop renewable energy projects, one promising option is central station solar power (CSSP).
Here Comes Cyber Security
Same power plant, different point of view. Where some might see hard physical assets that include a boiler, generator, turbine and emission control equipment, others—in particular those who work with the plant’s data and security—might see a network of data points, routers, servers and display panels.
A Big “If”
In light of spiraling costs coming from every direction coupled with a sagging economy, the thought of making electricity even more expensive than it already is may not be a pleasant one.
Compliance Is a Four-Letter Word
Air permitting people love acronyms. And have you noticed that they all seem to sound the same? You’re not imagining things.
POWER-GEN International @ 20:A Look Back at Issues and Events from 1988
Twenty years ago on page 6 of the January 1988 edition of Power Engineering magazine, a full-age ad introduced “POWER-GEN ‘88” to the world.
Technologies Shine on Parabolic Trough Solar Plants
After more than a decade of hibernation, parabolic trough concentrated solar power (CSP) has emerged from its slumber with a mighty roar.
10 Ways Generating Assets Become “Sub-Optimized”
The staff of most every power plant believes that their plant is “good” or at least “above average,” with the exception being those plants that have suffered with problems for so long that it has become painfully obvious that they could do better.
The Elephant in the Room
Ongoing talk about the nuclear renaissance is both exciting and encouraging, but it always must dance around the elephant in the room: project finance.
Fiberglass Pipe Replaces Wood Stave Penstock
Jackman Hydro Station, built in 1926, is one of nine hydroelectric plants owned by Public Service of New Hampshire (PSNH).
Carbon Sequestration Efforts Advance
New coal projects designed to capture carbon dioxide (CO2) appear to be on hold pending national legislation that would set standards, laws and regulations for doing so—and also establish a price for carbon.
Products
SMA America Inc. released the Sunny Island 5048U.
Three Questions
Basin Electric ran a print and radio ad campaign in North Dakota, South Dakota, Minnesota and Montana beginning in May that asked the public to question whether or not federal climate change legislation makes economic sense.
