Using Turbine Performance to Improve your Maintenance Strategy

Wednesday, December 2, 2020 @ 2:00pm EST/11:00am PST

Presentation Synopsis

Knowing performance shortfalls and most likely cause of the loss prior to the outage can reduce outage duration and cost. We will give examples of pre-outage performance test results and what was found during the steam path audit to identify the source of loss. Presentation will cover how to use performance testing and analysis to improve effectiveness of outage maintenance.

Key Takeaways for Users

1 – Using performance testing and steam path audits as part of a turbine maintenance program can help improve performance and reduce maintenance costs.

2 – Comparing performance test results to steam path audit results will ensure identification of performance losses. Case studies will be provided to illustrate this point.

3 – Repairs should be prioritized based on cost of the repair and the estimated recovery.

4 – Performance testing and steam path audits help evaluate the internal condition of the turbine, but other factors should also be considered.

Presenter

James G Miller, P.E. Manager of Performance Services

JMiller-head-shotJames Miller received his bachelor’s degree in mechanical engineering from the University of Florida. He is a registered Professional Engineer in Florida. His expertise lies in thermodynamics and power plant performance analysis.

Mr. Miller is employed as the Manager of Performance Services at Mechanical Dynamics & Analysis, with corporate headquarters located in Latham, New York. He provides fossil, industrial and nuclear engineers with consultation on power plant performance, steam path audits, steam turbine performance analyses, power plant testing, and heat balance analyses.

Jim has 20 years of experience in the areas of thermal performance and performance testing for fossil, combined cycle, cogeneration and nuclear power generating facilities. Prior to working in the commercial power generation industry, Jim worked as a mechanic on submarines in the US Navy.

Mr. Miller has a wealth of experience gained from his work at a major utility in the southeast. In addition to his Performance Engineering work, he has worked as a Turbine Outage Planner, Maintenance Manager and Nuclear System & Program Engineer to broaden his knowledge base and skills.

With extensive experience in performance monitoring, performance testing, thermal modeling, causal analysis and identification of cycle losses, Jim can identify performance deficiencies and determine the necessary actions required to recover losses.

Mr. Miller routinely provides on-site steam path audit services that have saved operating costs by providing audit information used to make repair decisions that resulted in a reduction in heat rate and a decrease in annual fuel costs.

Jim has been involved in numerous performance tests on equipment from many different manufacturers. Testing experience includes component testing on gas turbines, combined cycle, fossil, cogeneration, industrial and nuclear steam turbines as well as overall plant performance testing.

Jim is passionate about improving plant performance and can help you reduce operating costs, improve reliability and increase output.
