Preparation keyed Entergy’s responses to Katrina, Rita
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.
Cheng Cycle flirts with 2 ppm NOx— and CO
Three years ago, an article in POWER described how Cheng Power Systems, by modifying the combustors of several popular gas turbines, had used steam injection to lower the units’ NOx…
How accurate primary airflow measurements improve plant performance
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.
Solving plant vibration problems
Solving insidious vibration problems in rotating equipment may sometimes seem like a black art that requires the right incantation. But identifying the root cause of the vibration is actually a…
