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

Compared with traditional HRSG cleaning methods, PressureWave Plus provides a more effective and efficient cleaning. How?

step1
stills-step1

Complete HRSG cleaning easily while offline

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

step2
stills-step2

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
stills-step3

No damage to tubing during cleaning

The resulting pressure wave and tube vibrations dislodge deposits without damaging tubing, and is repeated in many locations.

step4
stills-step4

A fast, deep cleaning

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