  What is fouling in heat exchangers? Crystallization:       Crystallization usually occurs in streams of cooling water containing dissolved sulphates and carbonates. As the solubility of these salts decreases as the temperature rises, it tends to precipitate on the heat transfer surfaces when the water is heated and forms scale. This type of pollution can be reduced by limiting the temperature of the exhaust water to a maximum of 110–125◦F. heat exchanger , heat exchanger fouling, crystallization fouling, shell and tube heat exchanger pollution, heat transfer heat exchanger problems, pollution types, scaling Dissolution: Some organic compounds can decompose when heated or come in contact with a hot surface and form carbonaceous deposits, such as coke and tar. In cracking furnaces, the goal is the partial decomposition of the hydrocarbon feedstock and the formation of coke is an undesirable but inevitable result. read more.....

  What is fouling in heat exchangers?                    Contamination is the accumulation of unwanted material on the surfaces of the heat exchanger tubes. After a period of operation, the heat transfer surface of the heat exchanger can be covered with various deposits that occur in the fluid system. This layer is an additional resistance to heat flow and therefore reduces performance. Pollution factors are best determined based on experience with similar units in the same or similar service. If such information is not available, it may be necessary to publish data. The most comprehensive table on pollution factors is the one developed by TEMA, which is available from Ref. Contamination can occur through various mechanisms that work alone or in combination.  Corrosion:           Corrosion products such as rust can gradually build up on tube walls, resulting in reduced heat transmission and eventual tube failure. This type of fouling can be minimized or eliminated by the proper choic

  Hi, Pravin here and welcome to another exciting and interesting video on engineering machinery. Now, in this blog, we`re gonna be talking about the shell and tube heat exchanger . Some of you might think you know a lot about shell and tube heat exchangers and that's fine. Then you can read this blog and it will just reinforce what you already know. Some of you might not know anything about shell and heat exchanges and that's also fine because you`re going to learn a lot in this blog.  read more...

             let's take a look at all the main components that make up a shell and tube heat exchanger . I will show you some of its design features, these are the pros and cons and I will also show you how it works. so let's start. now, this is not what a housing and tube changer normally looks like in the workplace. If it were, it would be much easier to understand how it works. Let's fix the configuration tool for a moment and now you can see the balance and the tube heat exchanger as it normally would be in the workplace. There are different variation designs, but this is quite standard. So, let's start looking at the outside of the heat exchanger.         We have the reservoir, it is a pressure vessel, which means that it will be under pressure to correspond to the pressure of the fluid or the system that flows through it or specifically through the reservoir. Sometimes, people also refer to the wrapper as the box. We also have a front and a rear part of the heat e

 Extended surface heat exchangers In some applications, a much higher exchanger efficiency (up to about 98%) is essential, and the volume and mass of the box are limited so that a much more compact surface is mandatory. plate and Tubular exchangers are all main surface heat exchangers, except for a shell and tube exchanger with low finned tubing In addition, in a heat exchanger with gases or some liquids, the heat transfer coefficient is quite low on one or both sides of the fluid. This results in a great need for the heat transfer surface area. One of the most common methods for increasing the exchanger's surface area and compaction is to add the extended surface (fins) and use fins with the density of the fins (frequency of the fins, fins / m or fins / in.) As high as possible in one or both sides of the fluid, depending on the project requirements. The addition of fins can increase the area of surface by 6 to 15 times the primary surface area in general, depending on the design

 Heat Exchanger Manufacturer In India            Equipment often necessary and found in the practice of heat transfer is the so-called “ heat exchanger ”. Basically, this is the device that allows the transfer of energy, due to the temperature difference, between a hot fluid and a cold fluid. it occurs through a solid barrier that interposes between the two fluids to prevent their mixing, or to and from this solid wall as a result of the alternating passage of hot and cold fluids over the barrier. In the figure below is a schematic image of such a general heat exchanger. In general, there are also, as shown in the figure, other surfaces whose function is to confine one or both fluids and which essentially do not have heat transfer through them. In many heat exchangers, the barrier between the fluids will be a pipe wall or a flat wall and the other containment barriers can be circular cylindrical surfaces or flat surfaces.
