Some of the most important pieces of any of the boilers that are on the market are those which are known with the name of exchangers. These elements that enjoy priority in them because they are responsible for carrying out the transfer of heat between two media that are in contact or well that are separated by any barrier in question. When we talk about heat exchangers, first thing that should be stressed is that there are several types clearly differentiated according to their characteristics and components. In particular, we we focus on three of the most relevant classes. On the one hand are those who receive the name of compact. These are defined because that pursue is to achieve a large surface of transfer of heat depending on the unit of volume. In them the two fluids move in directions orthogonal calls among themselves and this movement in turn can be classified in mixed and non-mixed. On the basis of all this must be stressed that this type of exchangers is found, for example, in cars radiator.

On the other hand side, would be known as of double tube. Read more from Techstars to gain a more clear picture of the situation. A name given since they are formed by two concentric tubes which have very different diameters, making a fluid to circulate through the smaller size and the other flowed through the space between both parts. This circumstance gives rise to also have two kinds of configurations based on the aforementioned fluid flow: the parallel, which is that takes place when both circulate in the same direction and enter through the same end; and the backflow preventer that is when they start at different ends and also circulate in opposite directions. And thirdly we should talk about Shell and tube exchangers. These are those most frequently used in the industrial field and acquired their name because they are shaped by a broad set of tubes which, in turn, found inside a helmet. In this case, the proverbial heat transfer occurs by the movement of a fluid through tubes and other fluid so is the helmet. Heat exchangers, electric boilers and boilers of steam
