Heat ExchangersIntroduction
The energy from nature have to be converted into useful work. This can be achieved by transferring the energy from one fluid to another fluid either by conduction,convection or radiation or with all the three modes of heat transfer. manufacturing some special heat transfer equipments or devices to transfer heat energy from one source to another to transfer energy effectively. One such equipment which most efficient in transferring heat from one fluid to another fluid is Heat Exchangers.
what is Exchanger ?
Heat exchangers are intended for high pressure BOILERS that is used for transferring Heat Energy from one media to another media (ie. between fluids ) Generally it is suitable for High pressure applications.
Design Criteria Operation
Fundamental concepts involved in common types of heat exchange equipments have many design approaches considering in addition to the thermal properties of the substances , the temperature and chemical properties of the heat transferring substance, the weight and size and space requirement of heat exchangn equipment with economic consideration and the capablity of long lasting service of equipment etc. are taken for consideration for designing the Heat exchanger equipment called Heat exchangers.
Heat exchanger consists of a shell called pressure vessel large in size with a bundle of tubes inside it. This arrangement is to transfer heat from one fluid to the other while One fluid runs through the tubes, and another fluid flows over the tubes through the shell .
Operation
Primary function is to transfer heat from the hot fluid to cold fluid most efficiently.
During flow of high temperature fluid it transfers heat through conduction,radiation and convection or all of the three
Types of Heat Exchangers Classification
There are basically three types of Heat Exchangers according to its working features.
1. Recuperative
2. Regenerative
3. Mixed Type
These Heat Exchangers are further classified into three main groups according to the direction of flow of fluids.
1. Parallel flow
2. Counter flow
3. Cross-flow
