REDUCING COSTS

Greater efficiency leads to cost savings

Having a clean heat recovery steam generator (HRSG) is integral both for your plant reliability and efficiency. PressureWave Plus™ improves backpressure to near-design specifications, while improving full and minimum CC heat rates and increased plant performance.

Our facility saw a 5" reduction in GT backpressure as a direct result of the GE Pressure Wave cleaning on a single HRSG, from 23" H2O down to 18" H2O. This increased plant summer output by around 5 MW total from just a single HRSG cleaning. Winter output had been limited due to the increased mass flow, and backpressure surpassing the trip limits. The cleaning allowed us to avoid a 20+ MW reduction in winter output by gaining margin to the exhaust pressure trip limit

PRESSUREWAVE PLUS

A more effective way to clean

GE offers a solution for effective tube cleaning for all HRSG types. PressureWave Plus™, developed by BANG&CLEAN® Technologies AG, uses controlled pressure waves to penetrate deep into the tube bundle for a more effective and efficient cleaning.

deeper-clean

Pressure waves penetrate deep into the module, achieving a better cleaning compared to alternative cleaning methods

no-scaffolding

No need for scaffolding, which makes it a safer, faster, and more cost-effective solution

half-the-time

Can be completed in a much shorter cycle compared to other methods, without damage to tubing

PRESSUREWAVE PLUS

How it works

step1
PressureWave Plus Enhanced Image1

Complete HRSG cleaning easily while offline

PressureWave Plus cleanings can be completed in parallel to regularly scheduled gas turbine maintenance, reducing plant downtime.

step2
PressureWave Plus Enhanced  image2

No scaffolding needed

A special lance is introduced into the area between the pressure part modules. A bag at the end of the lance is then inflated with a combustible mixture which is ignited remotely.

step3
PressureWave Plus Enhanced image3

No damage to tubing during cleaning

The resulting pressure wave and tube vibrations dislodge deposits without damaging tubing, and is repeated in many locations. This provides a more effective and efficient cleaning as compared to traditional HRSG cleaning methods.

step4

A fast, deep cleaning

Once the HRSG tubing is thoroughly cleaned, the debris is removed from the floor of the unit.
