New Exclusive Workshop from Intek!

Condenser Performance: Essential Monitoring, Air In-Leakage Valuation, and Reporting

July 10 – 11, 2018

This online workshop, presented through Energy-Tech University, will include case studies and technical materials that have been demonstrated to be impactful on plant engineers and managers. The presentation will include general knowledge about condenser design and operation, as well as information that highlights best practices, efficient troubleshooting, essential fundamentals, and valuable condenser performance related tools and analysis techniques.

Information presented will cover nearly all maintenance and design related performance deficiencies but will have a primary focus on budget-minded instrumentation, air in-leakage, and condenser upgrade potential.

ILS-Integrated Lab Solutions Uses Rheotherm Model 210
in High-Temperature Reactor

ILS-Integrated Lab Solutions, based in Berlin, solved a difficult application challenge in their Vinyl Acetate Monomer Reactor using Intek’s Rheotherm Model 210. The process, which involves extremely high temperatures and low flow rates, could not be controlled using most commercial thermal mass or Coriolis mass flow controllers. The application required the selection and integration of both a flow sensor and a control valve capable of handling both the high temeperature and the corrosive acid used in the process. They chose to use a high-temperature Intek flow meter combined with an Equilibar dome-loaded multiple orifice control valve.

Condenser Monitoring Instrumentation Identifies Abnormal Condition

This article describes how Intek’s condenser instrumentation, which was installed to monitor condenser performance at East Kentucky Power Cooperative’s Spurlock Generating Station, helped the plant to identify an abnormal condition caused by debris in the cooling water before it caused major damage to the system.

Condenser Performance Response to Air Ingress (Air In-Leak) and Exhauster Operation

In this article, Intek engineers explain how the measurement of a new parameter provided exclusively by Intek’s RheoVac Air In-Leak Monitor can help identify the source of condenser performance issues including excess back pressure, reduced heat rate and output, increased DO and other performance-stealing problems.

Power Magazine article: Improve Condenser PerformanceThrough Better Instrumentation

This linked article discusses the value power generation plants receive from having appropriate online monitoring of plant parameters. One of the Case Studies looks at a plant’s experience with real-time air in-leakage monitoring. Read more by clicking here.

Installation of Steam Side Retrofit Results In Lower Condenser Pressure (0.6-1.0″ HgA)

Performance study by Intek on an Ingersoll Rand and a Westinghouse condenser concluded that the condensers were 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 to both units 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 New Tool for Reducing Back Pressure

An 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 used in power plants, 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 came to Intek for a solution to their unique 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.

Condenser Performance: Meaningful Data with Minimal Instruments

In this presentation from the EPRI Condenser Technology Conference, Intek engineers Collin Eckel and Dr. Tim Harpster describe the instruments developed by Intek for shell and tube heat exchangers and their measurements made in operating large scale condenser units. The results obtained from analyzing the data provided by these instruments have been used to design upgrades for underperforming steam surface condensers.
