Achieving Efficiency and Reliability in Air-Cooled Condensers with Effective Cleaning, Testing and Inspection

Presented by Gary Fischer, BS, MBA of Conco Services Corporation

Achieving the perfect balance of efficiency and reliability in your Air-Cooled Condenser (ACC) is attainable through effective cleaning, testing and inspection.

Presentation Takeaways

Because of the large surface area of ACC units and the absence of cooling water, operating costs can be much higher than water-cooled equivalents, especially in hot summer months. Conco’s automated ACC cleaning uses a computer driven carriage and precision water jets that match fin geometry to safely and quickly remove fouling and debris.

Conco engineer Gary Fischer will discuss fouling tendencies in ACC units, the real-time impacts of fouling, the importance of keeping fin tubes free of debris, offline and online ACC cleaning options, as well as a case study of choked finned tubing in a Montana, USA plant.

 

Optimizing Generator Testing and Inspection During Your Turbine Outage

Developing and Implementing an Effective Generator Assessment Program
Presented by Phil Karwowski, EthosEnergy Group

The generator is routinely overlooked when developing an operation and maintenance program. As fleets mature, the potential for availability-limiting events caused by the generator continues to increase. However, if an operation and maintenance program is developed early to coincide with the outage windows of the turbine, forced outages can be minimized and availability requirements managed. EthosEnergy offers such a plan with its Generator Assessment Program (GAP).

Presentation Highlights

  • Discussion of different levels of testing and recommended inspections
  • Review of key potential failure mechanisms identified and corrected during outages.
  • Successful risk management and life cycle optimization by implementing a proactive GAP.

501F Compressor Solutions

Rotor Unstacking and Compressor Rotor Repair
Presented by Fernando Romero, Sulzer Rotating Equipment Services

The case studies in this presentation showcase two separate instances where cracks were detected on the W501 compressor low pressure stubs. The presentation includes a basic overview of the rotor design and construction as well as a step by step explanation of the unstacking process. A repair solution is presented as it was applied on the first rotor where such failure was detected. The solution was implemented successfully and the rotor has been in operation for more 36,000 hours.

501F Compressor Diaphragm Repair
Presented by Fernando Romero & Matt Walton, Sulzer Rotating Equipment Services

501F compressor diaphragm wear and tear is a natural occurrence for any operator. In this presentation Sulzer reviews 501F diaphragm construction and the primary damage and failure modes typically seen in these machines. Typical and advanced inspection and repair processes will be reviewed to guide users’ understanding of disassembly and repair methodology and what to observe during shop/major repairs. After viewing, users will have gained insight to generally diagnose compressor diaphragms that need to be repaired versus rows that can be left in the machine.
