Systems and methods for cleaning a heat recovery steam generator system including tubes and fins associated therewith using deep cleaning alignment equipment are described. The deep cleaning alignment equipment primarily includes at least one wedge and at least one wand. The wedge may be an elongate wedge configured to maximize the surface area that contacts the tubes and fins, which in turn minimizes the amount of stress about any specific point of the tubes or the fins. Additionally, the wedge may be made of a soft, composite material, such as a high strength carbon fiber nylon. The composite material is softer than the material that makes the tubes and fins. As a result, when the wedge contacts the tubes and fins, the tubes and fins will not sustain damage. Instead, any damage that may occur would be to the wedge.

A heat exchanger is disclosed having a first cylindrical tube and a lead screw which extends coaxially inside the first cylindrical tube; the inner surface of the first cylindrical tube has guiding grooves, and a cleaning element is secured to the lead screw in such a way that a rotating movement of the lead screw moves the cleaning element in the axial direction along the guiding grooves.
