HRSG Cleaning: Project Case Study

ExPro Services patent pending Kinetic Energy Cleaning System for cleaning combined cycle HRSG’s is the Most Effective HRSG Cleaning Method Available. A case study of two 174 megawatt HRSG units cleaned at a facility in West Texas reflected the following results: The cleaning was required due to elevated back pressure in both HRSG units. It had been a number of years since the units had last been cleaned. ExPro Services’ process was able to reduce the back pressure on the first unit from 7 to 3 and 9 to 5 on the second unit.

ExPro Services completed the cleaning with:

  • No scaffolding required
  • No tube spreading required
  • The plant needed to repair dampers, this maintenance was accomplished in conjunction with blasting operations
  • The project was completed within the 3 day’s (6 shifts) per unit, as was originally estimated.
