Installation of Steam Side Retrofit Results in Lower Condenser Pressure (0.6-1.0" HgA)
A performance study by Intek on an Ingersoll Rand condenser concluded that the condenser was under performing. Intek's advanced instrumentation subsequently identified air storage in the steam space as the main culprit for the poor performance. A condenser retrofit designed by Intek and installed during a retubing outage eliminated the air storage and significantly improved condenser performance. Read more (PDF)
Circulating Water Flow and Fouling Meters: A Tool for Reducing Back Pressure
A recent article in Energy-Tech magazine highlights the valuable information provided by Intek's unique Circulating Water Flow and Fouling (CWFF) meters. Part of the Rheotherm family of precision flow instruments, these CWFF meters gave the subject power plant a look at the water flow conditions in the circulating water system in an effort to combat microbiological influenced corrosion. In addition, a clearer picture was obtained of circulating pump operation, debris flushing efforts, and eductor plugging. Read the article (PDF)
Helping a Nuclear Power Plant Solve a Problem
Based on Intek's extensive experience with condenser operation and design, a nuclear power plant recently came to Intek for a solution to a problem. An issue encountered during outage work in the condenser needed to be accurately, and quickly, analyzed. A thorough analysis of the problem, with a specific recommendation was provided within a week.

Optimizing Condenser Performance: A Case Study
Intek undertook a project to improve the performance of a 37 year old condenser during a retubing outage. Since coming back on line after the retrofit, the plant has achieved record low condenser pressures for equivalent operating conditions, record low condenser condensate DO levels below 4 ppb, a 200% increase in polisher resin life, and a 6% heat rate reduction for the two years following the retrofit outage.

Intek Modification Reduces DO by 70% at Entergy Little Gypsy
Entergy’s Little Gypsy, Unit 2, is a 450 MW unit originally designed for base load operation. Since becoming a peaking power operation, the plant has had problems with excessive dissolved oxygen (DO), especially during periods of low load. Intek, Inc was contracted to identify and correct condenser design deficiencies responsible for the high DO. The result was a 75% reduction in DO at only 5% of full load. At 22 MW, dissolved oxygen decreased from 22 to 5 ppb and at 180 MW, dissolved oxygen was reduced from 13 ppb to 2 ppb (below the range of the DO meter). Click here to learn more.
