Abstract: A heat exchanger has an intake header, a discharge header, a bundle of tubes extending in parallel between the intake header and the discharge header, an intake pipe connected to the intake header and extending transversely to the axes of the tubes of the bundle, the intake pipe having a first end opening into the header and a second end connectable to a process fluid supply pipe, and a baffle assembly for modifying the direction and rate of flow of the process fluid through the intake header, the baffle assembly being located within the intake pipe and secured to the intake pipe at a position adjacent the second end of the intake pipe. The baffle assembly comprises a plurality of slats lying in planes generally parallel to one another and inclined to the direction of fluid flow, and runners connected to the ends thereof to form a rigid structure.

Abstract: A method is disclosed for cleaning the shell side of the core of a heat exchanger formed of a set of tubes passing through transverse plates which include two end plates and at least one baffle plate. A hole is first formed in an end plate in a region between core tubes. A lance is next inserted into through the hole and used to jet the section of the core between the end plate and the first baffle plate. A boring tool inserted through the hole in the end plate is then used to drill a hole in the baffle, allowing the cleaning process to be repeated for further sections of the core.
