KNOWLEDGE and EXPERIENCE is needed to develop and implement an effective heat rate monitoring and improvement program. HPC Technical Services will provide the fundamental knowledge. Then, with this knowledge, experience can be applied more effectively as you're better prepared for the tasks at hand.
  • Are high fuel costs having an impact upon your plant's bottom line? Improved efficiency can help survive these costs.
  • Do long-term fuel contracts have you down? Improved efficiency can help lift you back up.
  • Are you evaluating the competitive positioning of your plant? Improved efficiency will certainly improve your market positioning.
  • Are you new to this position and/or just been given these responsibilities? If yes, this Seminar gives you a significant head-start over the OJT approach.
The Seminar is designed to provide combined cycle power plant personnel with the fundamental knowledge to be able to begin the development, or to implement an effective heat rate improvement program. Design and operating theories of combined cycle plant equipment are presented. Thermodynamics and heat transfer are reviewed and practically applied to operation. Calculations are performed, using actual test data, to determine steam and gas turbine efficiency, condenser cleanliness, turbine cycle heat rate, corrections, HRSG efficiency, and feedwater heater performance.

At the successful completion of this Seminar the attendee will be able to:
  1. Describe the thermodynamic principles that apply to a steam turbine, gas turbine, HRSG within a combined cycle power plant.
  2. Describe the operational / performance factors that impact the combined cycle performance.
  3. Demonstrate an understanding of the level of testing and monitoring required to determine plant heat rate performance.
  4. Describe the major steps required to perform 3 major component performance tests.
  5. Demonstrate the ability to analyze plant performance data to determine where component efficiency has deteriorated
  6. Determine realistic heat rate improvement goals
  7. Develop corrective action plans to achieve the established heat rate performance goals.
  8. List the types of measuring equipment and perform the calculations required to analyze plant performance.
