摘要： The invention relates to a method for cleaning a heat exchanger. The heat exchanger comprises a plurality of tubes extending between a first header and a second header, and further comprises an insertion unit for introducing a plurality of projectiles thereinto. A first step of the method comprises pumping a fluid into the first header. A second step comprises inserting the plurality of projectiles into the fluid, such that the plurality of projectiles are distributed within the fluid. A third step comprises flowing the fluid and the projectiles through the tubes, such that the projectiles abrades at least one tube. A fourth step comprises discharging the fluid and the projectiles out of the second header. Among the plurality of projectiles, at least one projectile has a different specific gravity, relative to the fluid, from at least one of the remaining projectiles.

摘要： Fluid is circulated through a heat exchange system for heat exchange to occur at a bundle of tubes making up a portion of the heat exchange system. Heat exchange efficiency at the bundle of tubes requires debris and fouling deposits accumulated therewithin to be substantially removed. Taking the heat exchange system off-line for physical flushing is not only ineffective but also disallow use of the heat exchange system for the duration it remains off-line. Described herein is an embodiment of a cleaning system which uses a displacement system for displacing cleaning balls carried in fluid into the bundle of tubes for cleaning thereof. A flow diverting system is configured and operable for introducing the cleaning balls to the bundle of tubes when in a first operating mode and for retrieving the cleaning balls from the plurality of tubes when in a second operating mode.
