A desire to do things right led Constellation Energy to invest $70 million to convert its 400-MW C.P. Crane Generating Station to burn Powder River Basin coal and develop the culture critical to making that conversion a success. In addition to being named a 2012 POWER Top Plant, the PRB Coal Users’ Group recognized the plant for its efforts with its Plant of the Year Award

Sierra Instruments launched a new cryogenic version of its InnovaMass 240 multivariable mass vortex flow meter for advanced, more reliable measurement of liquefied gases, including liquid nitrogen, liquid oxygen, liquefied natural gas, and liquefied petroleum gas, down to –330F. The InnovaMass contains no moving parts that will wear out or require service. This new meter […]

To comply with the New Hampshire law governing mercury emissions, Merrimack Station management recently installed a single scrubber system on the facility’s two coal-fired boilers. The plant’s Clean Air Project was completed on Mar. 30, 2012, ahead of schedule and under budget. Now the 440-MW Merrimack Station has reduced its mercury and sulfur dioxide emissions by more than 95% and is one of the cleanest coal-fired power plants in the nation

The Deltabar FMD72 Electronic Differential Pressure measurement system launched by Endress+Hauser uses two pressure sensor modules connected electronically to a single transmitter and eliminates the need for impulse lines or capillaries and their related issues of icing up, clogging, leaky taps, dry/wet leg inconsistencies, and problems with temperature changes. Ambient temperature changes cause measurement drift […]

Since the Northside Generating Station’s two repowered units were placed into service in 2002, a series of modifications and repairs have been undertaken to make its two circulating fluidized bed boiler plants reliable. The two chief problems were ash agglomeration on heat transfer surfaces and poor Intrex heat exchanger performance. JEA reports these problems have been permanently resolved, and data shows the two units have joined the top tier of reliable fossil plants.

The brave men and women of the U.S. military spend years crafting special skills and developing traits that prepare them for the challenging assignments they will be given throughout their terms of service. They receive orders for tours of duty and venture without hesitation into places steeped in peril and instability. Because of their consistently courageous responses to unimaginable challenges, civilians herald America’s servicemen and women as heroes. How can we begin to repay our veterans for defending our freedom?

Units 3 and 4 expand the Tanjung Jati Electric Generating Station’s capacity by adding 1,320 MW of reliable power that helps to boost Indonesia’s growing economy. Now the 2,640-MW coal-fired facility provides approximately 12% of the electricity available on the Java-Bali grid. The new units feature a flue gas desulfurization system and electrostatic precipitators that reduce air emissions and protect the environment.

Dominion’s 585-MW Virginia City Hybrid Energy Center, located in southwestern Virginia, relies on two circulating fluidized bed boilers that burn coal and local waste coal mixed with up to 20% biomass. The project also features one of the industry’s largest air-cooled condenser systems to minimize the plant’s water usage. The $1.8 billion project entered commercial service July 10, on budget and on schedule

The 1,309-MW Claus C power plant showcases the successful repowering of an existing steam power plant by upgrading it and adding a highly efficient combined cycle plant that doubles the original plant’s power output for just a 35% increase in fuel consumption. In addition, the newly retrofitted plant is cutting CO2 emissions by 40% compared with a simple-cycle gas-fired plant of equal capacity.
