Improve HRSG Efficiency
Boiler deposits of iron oxide and ammonium bisulfate on the flue gas side can lead to tube fouling of heat recovery steam generators. This reduces the heat transfer efficiency and increases backpressure on the adjoining gas turbine. Additionally, it lowers the HRSG and turbine efficiency, which can lead to higher operating costs.
A heat exchanger cleaning system is required for an effective tube bundle cleaning solution. GE offers innovative cleaning boiler technology through PressureWave PlusTM, developed by BANG&CLEAN® Technologies AG, that uses pressure waves to penetrate deep into the tube bundle for a more effective boiler cleaning.
How PressureWave Cleaning Works
Pressure wave cleaning for boilers and HRSG tubes is done with a special lance, which is inserted into the spaces between the tube bundles. A bag at the end of the lance is then inflated with a mixture of combustible gases which are remotely ignited. The resulting pressure wave and ultrasonic tube vibrations dislodge and clean the deposits from the boiler without damaging the boiler tubing.
Pressure wave cleaning is much faster than the traditional method of CO2 blasting—it can be done in about half the time—and it requires no internal scaffolding. This heat exchanger tube cleaning technology is also much more effective at removing corrosion, as the pressure wave cleaning can reverberate into areas previously unreachable by other industrial boiler cleaning methods.
