Kansas City Power & Light Installing SCR at La Cygne Generating Station Kansas City Power & Light (KCP&L), a subsidiary of Great Plains Energy, has awarded The Babcock & Wilcox Company (B&W) a contract for the installation of new emissions control equipment on Unit 1 at its La Cygne Generating Station. When completed, the selective […]
St. Johns River Power Park (SJRPP) is a two-boiler, 2 x 660-MW station jointly owned by JEA (formerly Jacksonville Electric Authority) and Florida Power & Light (FPL). JEA is the plant operator. The Foster Wheeler boilers went into commercial operation in 1987 and 1988. Each boiler has seven OEM vertical spindle pulverizers (mills) and 28 […]
If engineered well and drained properly, a simple finned-tube heat exchanger can help maximize a fossil-fueled power plant’s combustion efficiency, capacity, and air pollution reduction. Use the guidelines in this article either to return a disabled steam coil air preheater to service or to improve the performance of a unit that may have been wasting […]
Primary airflow has a major impact on the efficiency, capacity, and cleanliness of pulverized coal–fired generation. Inaccurate measurements that underestimate primary airflow levels can lead to negative operational outcomes that include increased boiler gas temperatures, flyash loss-on-ignition, excessive NOx emissions, and higher-than-necessary fan power consumption. We remind you how to avoid those headaches.
Understanding why stack emissions become opaque leads to better choices of systems for controlling SO3 and other pollutants, based on current and future plant operating configurations.
With the 2006 hurricane season about to begin, climatologists are predicting that the Atlantic Ocean will spawn 17 “named” storms this summer and fall, with 9 categorized as hurricanes and 5 expected to be “intense.” Whether or not your plant lies in a vulnerable coastal area, you’d do well to learn a few lessons from Entergy’s unique experience last year.
T/P92 is being heralded as a superior and lower-cost alternative to T/P91 for new power plants with pressures above 3,600 psi and temperatures above 1,100F—such as the supercritical and ultra-supercritical units proposed to be built in the U.S. over the next few years. The switch from T/P91 to T/P92 would represent the next step in […]
The California Energy Commission (CEC) recently awarded about $14 million for carbon sequestration projects to be overseen by the West Coast Regional Carbon Sequestration Partnership. Westcarb, as the partnership is known, is part of the U.S. DOE’s effort to deploy technologies through its Regional Carbon Sequestration Partnership (RCSP) program. New members Alberta and British Columbia […]
Increased cycling of combined-cycle plants has made precise control of attemperator spray water within heat-recovery steam generators more important if damage to their hardware and piping is to be avoided. Complicating the issue is the industry’s still-limited experience with cycling and the fact that demands on the attemperator and turbine bypass of cycled plants are more stringent than those on baseloaded units.
