Design of Ortho Two Potassium Heat Exchanger
Abstract: Ortho two potassium heat exchanger was designed in this paper. The main task is to design a horizontal shell and tube heat exchanger. Under the given conditions and resistance to the thermal design of heat transfer design combined with the structural design calculations, structural design is mainly housing, chamber, head of design with the design of some parts, shell, tube box and head are primarily designed to determine the thickness and form. In the design of components designed for the tube sheet is more complex, taking into account the pressure tube plate is a critical component, its design is quite critical, need to be pre-estimated, after the check. Then the design of other components, such as the pressure vessel flange flange design is a complicated place, we must consider that a good air tightness, and also taking into account processing. Finally using ANSYS finite element analysis carried out over the stress of opening reinforcement.
KeyWords: shell and tube heat exchanger; heat transfer design; structural design; finite element analysis
