Design & Analysis of Shell & Tube Type Heat Exchanger

Shell and tube heat exchanger

Shell and Tube Heat Exchangers are one of the most popular types of exchanger due to the flexibility the designer has to allow for a wide range of pressures and temperatures. There are two main categories of Shell and Tube exchanger :. Regardless of the type of industry the exchanger is to be used in there are a number of common features see Condensers.

Undergraduate thesis, undip. Heat Exchanger is the equipment used to perform the process of heat exchange between two fluids, both liquid hot or cold and gas, where this fluid has different temperatures. Some types of heat exchanger are frequently used shell and tube heat exchanger, double pipe heat exchanger and plate heat exchanger. This research aims to determine the rate of heat transfer with temperature variation on the inlet tube and knowing the effective efficiency on heat exchanger shell and tube type. From these data, it is the heat exchanger is a heat exchanger used for fluid warming or fluid cooling process.

Abstract:- Shell and Tube heat exchangers are having special importance in boilers, oil coolers, condensers, pre-heaters. They are also widely used in process applications as well as the refrigeration and air conditioning industry. The robustness and medium weighted shape of Shell and Tube heat exchangers make them well suited for high pressure operations. The basic configuration of shell and tube heat exchangers, the thermal analysis and design of such exchangers form an included part of the mechanical, thermal, chemical engineering scholars for their curriculum and research activity. Heat exchangers are used to transfer thermal energy between two or more media and widely applicable to chemical industries, food industries, power engineering and so on. The shell. Shell and Tube heat exchangers are having special importance in boilers ,oil coolers, condensers, pre-heaters.

Shell and tube heat exchanger

In this study, several types of baffle including segmental baffle, butterfly baffle, helical baffle, combined helical-segmental baffle, combined helical-disk baffle and combined helical-butterfly baffle are examined. Two important parameters as the heat transfer and pressure drop are evaluated and analyzed. Based on obtained results, segmental baffle has the highest amount of heat transfer and pressure drop. This investigation showed that among the presented baffle types, the heat exchangers equipped with disk baffle has the highest heat transfer. In addition, in the same mass flow rate, the performance coefficient of the shell and tube heat exchanger equipped with helical-butterfly baffle is the highest among the proposed models.

Shell and tube heat exchangers are used in various industrial processes, and are one of the most commonly used heat exchangers. The pressure drop in the tube and shell side was also investigated for all five cases in this study. The effect of the location of tubes on heat transfer was investigated. It was shown that tubes located near the shell have a greater impact on heat transfer compared with tubes located in the center of the shell. Shell and tube heat exchangers are used in various industrial processes [ 1 ].

A shell and tube heat exchanger is a class of heat exchanger designs. As its name implies, this type of heat exchanger consists of a shell a large pressure vessel with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes through the shell to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc. Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes the tube side and the other flows outside the tubes but inside the shell the shell side. Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa.

There are various types of heat exchangers used in process piping. Shell and tube heat exchanger is the most widely used heat exchanger and are among the most effective means of heat exchange. Shell and tube heat exchanger is a device where two working fluids exchange heats by thermal contact using tubes housed within a cylindrical shell.

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air.
