image-asset (5).jpeg

Paul Gremaud, Aftermarket Services Manager for Nooter/Eriksen will be discussing key areas of focus for HRSG owners and operators.  Major issues addressed will include:

  • The basics of a successful HRSG inspection program (daily and every outage)

  • Cyclic vs. baseload operation - reliability improvements

  • Risks of low load operation

  • The impact of cycling and fast starts due to market price opportunity

  • Specific reliability issues – condensate management, desuperheaters, water chemistry

  • Life assessment tools and assumptions

  • Need for large capital projects – coil replacements, grid/duct burner replacements, CO catalyst supply and installations

Below are some of the questions discussed during the webinar:

  • Is Nooter/Eriksen able to perform a gas side differential pressure (dp) review on non-Nooter/Eriksen equipment?

  • Can you discuss in more detail why HP Drum Manway System is so successful?

  • How do you remove the tube bends from the configuration shown?

  • Where do you install thermocouples?

  • Can you discuss failures?

  • At low loads during start-up, customer's plant is experiencing large vibrations that shake the HRSG. They have considered installing acoustic baffles in the SH sections, but the CIP project is 2 years old. Should they consider moving the project up?

  • What are typical inspection guidelines to support the reliability claimed here?

  • How old were the units on which LP evaporator coils or economizers were replaced?
