Entergy’s “big catch”
Entergy christened its Performance Monitoring and Diagnostic Center several years ago to leverage the expertise of its most senior operators and technicians across the company’s entire fleet of plants. The center also makes use of advanced software tools that increase plant availability and reliability by identifying faults before they become major, unplanned outages. The center paid for itself for years to come with a single “big catch” last year.

Boryeong Thermal Power Complex, Boryeong-Si, Chungcheongnam-do Province, South Korea
Top Plant: From tall skyscrapers and flashing neon signs to Buddhist temples and pagodas, South Korea is a mixture of the new and old Asia. Doing its part to help modernize this country, the Boryeong Thermal Power Complex operates six coal-fired 500-MW units that provide electricity to power South Korea’s economic growth. One of the important reasons for this facility’s overall success is its operational reliability. An example of this is Boryeong Unit 3’s outstanding achievement of 3,000 days of trouble-free operation.

Computer simulation as a NOx reduction design tool
A utility evaluated various methods of obtaining a NOx reduction of at least 30%, as required by upcoming regulations for its boiler, which originally produced 0.54 lb of NOx/million Btu at 410 MW full load. Nalco Mobotec engineers performed a computational fluid dynamics (CFD) simulation of the boiler to first understand the boiler’s combustion process and then determine the most economical method to achieve the required NOx reduction.

Dubuque Generating Station, Dubuque, Iowa
Top Plant: Alliant Energy’s Dubuque Generating Station is a fine example of why small doesn’t mean insignificant in the power generation industry. This winner of the EUCG Best Performer award in the small plant category shows that its operating excellence towers over that of many larger and much newer coal-fired power plants.

Double duty flowmeter
As fluid passes through Exact Flow’s new DX-DL dual-rotor turbine flowmeter, the dual rotors become hydraulically coupled due to their counter-rotation. Not only does this allow the rotors to overcome the inertia and drag that typically affect single-rotor turbine flowmeters, it also extends the flow range to 500:1—five times the 100:1 flow range of a […]

Transmission: Lines that connect the renewable energy dots
The United States is used to transporting fuels to electric generation centers that are close to where the power supply is needed. We see trains carry coal by the carload from resource-rich areas to generation centers across the country. Natural gas is distributed through pipelines. Even uranium is transported to supply our nuclear stations. However, […]
