Design & Analysis of Shell & Tube Type Heat Exchanger

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. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side.

There are various types of heat exchangers used in process piping. Shell and tube heat exchanger is the most widely used heat exchanger. Shell and Tube Heat exchangers can be used for wide temperature and pressure range. 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. The working of a shell and tube heat exchanger is fairly simple.

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 ].

Basics of Shell and Tube Heat Exchangers (With PDF)

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.

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.

The shell side usually contains theprocess fluid and the tube side water f;om the t o w n mains or a cooling tower or an ethylene glycol solution from a chiller unit. In certain circumstances this flow arrangement can be reversed, but please consult us first.

Effectively Design Shell-and-Tube Heat Exchangers (PDF)

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. A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell.

 - Потише и помедленнее. Что случилось. По голосу Стратмора, мягкому и спокойному, никто никогда не догадался бы, что мир, в котором он жил, рушится у него на глазах.

Беккер поморщился. - Предпочитаю вид спорта, в котором я могу выиграть. - Победа любой ценой? - улыбнулась Сьюзан. Защитник Джорджтауна перехватил опасную передачу, и по трибунам пронесся одобрительный гул. Сьюзан наклонилась к Дэвиду и шепнула ему на ухо: - Доктор. Он смотрел на нее с недоумением.

Introduction

Беккер дотронулся до руки погибшего авторучкой. - Может быть, он и жил. - Вовсе. Пересек границу неделю. - Наверное, хотел сюда переехать, - сухо предположил Беккер.

Цепная мутация. Она знала, что цепная мутация представляет собой последовательность программирования, которая сложнейшим образом искажает данные. Это обычное явление для компьютерных вирусов, особенно таких, которые поражают крупные блоки информации. Из почты Танкадо Сьюзан знала также, что цепные мутации, обнаруженные Чатрукьяном, безвредны: они являются элементом Цифровой крепости. - Когда я впервые увидел эти цепи, сэр, - говорил Чатрукьян, - я подумал, что фильтры системы Сквозь строй неисправны.

 - Мне нужен список очередности работы на ТРАНСТЕКСТЕ. Если Стратмор обошел фильтры вручную, данный факт будет отражен в распечатке. - Какое отношение это имеет к директорскому кабинету.
