Abstract (en)
[origin: WO0148434A1] A tube nest heat exchanger with shell under pressure has a lower inlet tube plate (12) separating the interior of the shell from an inlet manifold for arrival of the fluid to be cooled. The tube plate has fluid passages (14) and near the internal surface of the tube plate are side cleaning passages (35) for communication with the exterior of the shell and designed for introduction into the shell of means (45, 46) for cleaning the plate zone at the foot of the nest tubes. There can be inspection passages (38) near the plate surface for visual inspection of the zones to be cleaned.
