Design & Analysis of Shell & Tube Type Heat Exchanger

Introduction

Shell and tube heat exchanger

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. The fluid temperature inside the shell and tube are different and this temperature difference is the driving force for temperature exchange. Used for wide temperature and pressure range, Shell and tube heat exchangers are compact in design, easy in construction and maintenance and provide excellent heat exchange. As the name specified, it consists of a shell and a number of tubes. Shell is the housing of the exchanger and tubes are mounted inside the cylindrical shell.

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.

Design & Analysis of Shell & Tube Type Heat Exchanger

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. The heat exchanger then conducted the testing. The experimental results obtained were then compared with the result of theoretic.

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. Another example is the heat sink , which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant. There are three primary classifications of heat exchangers according to their flow arrangement.

TEMA designations for shell- and -tube heat exchangers. A disadvantage of this design isthat since the bundle is fixed to theshell and cannot be removed, the outsidesof the tubes cannot be cleanedmechanically. Thus, its application islimited to clean services on the shellside. However, if a satisfactory chemicalcleaning program can be employed,fixed-tubesheet constructionmay be selected for fouling serviceson the shellside. In the event of a large differentialtemperature between the tubes and the shell, the tubesheets will be unableto absorb the differential stress,thereby making it necessary to incorporatean expansion joint.

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.

Это ей снится. Трудно было даже пошевельнуться: события вчерашнего дня вычерпали все ее силы без остатка. - Дэвид… - тихо простонала. Ответа не последовало. Она открыла глаза, не в состоянии даже протянуть руку. Простыня на его половине кровати была холодной. Дэвид исчез.

Он был первым афроамериканцем на посту директора Агентства национальной безопасности, но эту его отличительную черту никто никогда даже не упоминал, потому что политическая партия, которую он поддерживал, решительно не принимала этого во внимание, и его коллеги следовали этому примеру. Фонтейн заставил Мидж и Бринкерхоффа стоять, пока сам он молча совершал свой обычный ритуал заваривания кофе сорта Гватемальская ява. Затем он сел за письменный стол и начал их допрашивать, как школьников, вызванных в кабинет директора, а они по-прежнему стояли. Говорила Мидж - излагая серию необычайных событий, которые заставили их нарушить неприкосновенность кабинета. - Вирус? - холодно переспросил директор.

Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике. Чуть впереди, у остановки, притормозил городской автобус. Беккер поднял. Дверцы автобуса открылись, но из него никто не вышел. Дизельный двигатель взревел, набирая обороты, и в тот момент, когда автобус уже готов был тронуться, из соседнего бара выскочили трое молодых людей. Они бежали за уже движущимся автобусом, крича и размахивая руками.

 Ну и проблема! - засмеялся Хейл.  - Думаю, коммандер мне его откроет. Разве не так, коммандер. - Ни в коем случае! - отрезал Стратмор. Хейл вскипел: - Послушайте меня, старина. Вы отпускаете меня и Сьюзан на вашем лифте, мы уезжаем, и через несколько часов я ее отпускаю.

 Боже всемилостивый, - прошептал Джабба. Камера вдруг повернулась к укрытию Халохота. Убийцы там уже не. Подъехал полицейский на мотоцикле. Женщина, наклонившаяся над умирающим, очевидно, услышала полицейскую сирену: она нервно оглянулась и потянула тучного господина за рукав, как бы торопя. Оба поспешили уйти.

Но он настолько устал, что ему было не до любопытства.

    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.

    Seamless tubing is produced in an extrusion process; welded tubing is produced by rolling a strip into a cylinder and welding the seam.
