Design of Floating head heat exchanger
Abstract: The design manual is about the floating head heat exchanger, which included the structure and intensity of heat exchanger. The design is according to the given design conditions design the structure and intensity of the floating head heat exchanger. This part is just on the selected type of heat exchanger to design the heat exchanger’s components and parts, such as vesting, baffled plates, the distance control tube, circle hook, tube boxes. This part of design mainly include: the choice of materials, identify specific size, identify specific location, the thickness calculation of tube sheet, the thickness calculation of floating head planting and floating head flange, the opening reinforcement calculation etc. In the end, the final design results through eight maps to display. The each aspects of the floating head heat exchanger has detailed instructions in the design manual.
Key word: Shell-Tube heat exchanger; floating head heat exchanger; tube sheet; floating head planting; floating head flange
