A common issue for combined cycle plants is deposition of combustion byproducts on HRSG pressure parts and other components which in turn can negatively impact performance. These can be a result of operating mode, equipment malfunction, fuel or duration between outages.
The consequences of operating with a HRSG experiencing gas side fouling include:
- Increased turbine exhaust gas backpressure
- Reduced heat transfer in the HRSG
- Excessive stack gas temperature
- Reduced steam production
- Tube and fin corrosion
- Reduced MW output
- Increased cost/MW
Now offering Certificates of Completion for all our Webinars.
The degree to which fouling impacts your plant will vary based on the plant design, operating mode, maintenance practices, plant location and fuel type, fuel source region and quality. Each of these factors will be discussed. Cleaning your HRSG can help your plant achieve optimal thermal performance and maximize your ROI.
Topics covered will include:
- Why deposits form
- Impact of deposits on HRSG performance
- Cleaning methodology
- HRSG performance monitoring plan
- Available cleaning methods
- Strengths and weaknesses of various cleaning methods
- High Pressure Blasting
- Deep Bundle Cleaning
