PressureWave+™ HRSG tube cleaning

Yes, we performed more than 200 cleanings in the last 5 last years without any safety issues.

None of our customers have experienced either short-term or long-term damage to HRSG components such as tubes, tube-to-header welds, casing liners, expansion joint and catalysts.
 

Yes, EPRI recently conducted an evaluation that found “No evidence of damage to tubes or other HRSG components…observed during these tests.” You can read the abstract here: Program 218: Heat Recovery Steam Generators | Product Abstract (epri.com). In addition, The University of Zurich and Bang&Clean conducted an independent study and concluded that “…in the considered realistic load cases, a permanent deformation due to the detonation can be excluded, unless both the boiler tubes and the weld seam are already weakened by overloading or corrosion.”

No, the PressureWave+ solution involves detonating a measured amount of gas, which is deployed inside plastic bags placed near the areas where buildup needs to be removed. We will tailor the solution to match the amount of cleaning your HRSG needs, which will involve either decreasing or increasing the cleaning force needed.
