What is Heat Exchangers ,Their Types and Applications

A heat exchanger may be simply based on a device that is configured to efficiently transfer heat from one medium to another. Heat exchangers are used in a variety of applications, such as heating, cooling, air conditioning, petrochemical plants, refineries and natural gas processing. In many industrial processes allows a heat exchanger to use waste heat from one process to be used in another process, which saves a lot of money, while efficiently.

There are several types of heat exchangers available, depending on their application in various sectors of the industry.

Shell and Tube Heat Exchanger:

Simply put, this heat exchanger uses a series of tubes containing the liquid that must be either heated or cooled, and these tubes run into a bowl or pipe a lot more one another Liquid contains either heated and heated tubes or absorbed and cools the liquid in small tubes. Shell and tube heat exchangers work best in high pressure and demanding environments.

Plate Heat Exchanger:

This heat exchanger works with a network of a plurality of thin and close plates, which have a very large surface area of ​​the fluid passages and for a better distribution of heat. Plate heat exchangers are more convenient compared to hull and pipe applications in applications where there is a restriction of space.

Adiabatic Wheel Heat Exchanger:

This type of heat exchanger uses a separate material, which can be a solid or a liquid material to store heat retained, which moves to the other side of the heat exchanger to be released.

Finned Plate Heat Exchangers:

Finned Plate Heat Exchangers are generally made of aluminium alloy with different models such as cross-flow, counter-current, with different types of fins, which lead to a transfer Very effective heat. However, they offer a disadvantage at times in the maintenance procedure properly due to extremely thin plates.

What is a heat exchanger?

 

What is a heat exchanger?

Suppose you have a gas central stove (boiler) that heats a hot water radiator in different rooms of your house. It works by burning natural gas, forming a line or grid of hot gas jets on top of the water flowing through a network of pipes. As water is pumped through the pipes, the heat energy is absorbed and heated. This arrangement we call through the heat exchanger: the gas jet cools and the water heats up.

                              

A heat exchanger is a device that allows heat from a fluid (liquid or gas) to flow into a second fluid (another liquid or gas) without the two fluids having to mix or come into direct contact. If that's not completely clear, consider this. In theory, we could get the heat from a burst of gas just by pouring cold water on it, but then the fire would go out! The important principle of the heat exchanger is that it transfers heat without transferring heat-carrying fluids.

Heat Exchangers Manufacturers In India | Galaxy Industrial Equipment

Galaxy Industrial Equipments Pvt. Ltd. is a leading manufacturer, supplier, exporter of high-quality heat exchangers. For efficient operation, most industrial applications use some type of cooling medium, which is generally fluid. Heat exchangers are used to cooling such fluids. Heat exchangers are industrial devices that transfer heat from one medium to another during the manufacturing process.  

Heat is transferred by conduction and convection through the exchanger material which separates the media being used. The hot fluid is cooled by dissipating heat into the cold medium. Heat exchangers are widely used in various industrial applications such as injection molding machines, blow molding machines, hydraulic presses, furnaces, pharmaceutical plants, food processing, dairy products, chemical processes, engines, and refrigeration. There are two types of heat exchangers: shell & tube type heat exchangers and gasket plate type heat exchangers. Galaxy Industrial Equipments Pvt. Ltd. offers both types of heat exchangers.

Shell and Tube Heat Exchanger:-

The shell-and-tube type heat exchanger regulates temperature fluctuations in the tube, and liquids such as oil and water flow through the shell pipe by dispensing coolant. The fluid to be cooled passes zigzag through the shell around a tightly mounted copper tube with a large number of baffles. The liquid transfers heat to the water and the water flowing through the copper tube follows multiple paths. This improves the water-fluid contact time for optimal heat transfer. This makes the heat exchanger very efficient.

Exhaust Gas Heat Exchanger

Galaxy Process Heat Exchanger Manufacturer, Shell and Tube Heat Exchanger.

Galaxy process - Heat Exchanger Manufacturer In India

Exhaust gas heat exchangers (exhaust gas heat exchangers) are devices specially designed for the exhaust gases on a heat carrier. The heat is transferred with a tube bundle. The exhaust gas can thereby be guided through the tubes of a straight tube bundle or also in the shell around the tubes. The decision for one or the other variant ultimately depends on an optimal flow guide and thus a good heat transfer, the possibility of cleaning the apparatus and a low pressure loss.

With regard to the other components in an exhaust pipe, such as silencers and catalytic converters, the total pressure loss according to the data sheet of the engine manufacturer must not be exceeded. Significantly lowering the permissible pressure loss, on the other hand, leads to a significant increase in engine efficiency and can be the goal of optimum plant design. This is because the higher motor efficiency is offset by the increased heating surface requirement and thus the higher costs of the exhaust gas heat exchanger.

A tube bundle heat exchanger can be designed in a variety of ways and can be designed to meet the special requirements as an exhaust gas heat exchanger. Water is used as a heat carrier, either as hot water or as steam, and various heat transfer oils (thermal oil / thermal oil) are used to make the exhaust gas heat of the engine usable for various application processes.

Heat Exchanger : Paper And Pulp Applications

Some industries will benefit more than others from certain industrial products or machinery. Heat exchangers are very popular across the board, but are for absolute basis the paper industry. Without heat exchanger paper mills have extremely high energy costs, which is bad for the environment and the portfolio size of the companies. There are a few ways that paper and pulp industry use heat exchangers, both financial strengthening, ecological methods, efficient and effective. Galaxy is Best Heat Exchanger Manufacturer In India.

Essentially, the paper process, starting with the processing of wood pulp and processing, then go into bleach and cleaning before paper formation, help with any heat exchanger. More specifically, plate heat exchangers are used to heat liquids that are used to produce wood pulp, a method which comprises chemical compounds which separate the wood structure, wherein a fork-like substance remains , Which can be further formed into paper. Secondary processes include discoloration or death of the pulp, which is a procedure that is heated by a plate or spiral heat exchanger. Once the desired color is reached, the pulp, paper, knitting on a paper machine, which form the paste into thin strips, leaves. Throughout the humidity is eliminated and some type of fan is used to dry completely.

Heat Exchanger

A part of the paper machine also uses a type of heat exchanger which is known as a waste heat recovery system, which is one of the means that heat exchangers are able to save energy Businesses, resources and money. Heat Recovery Machine is able to absorb heat and moisture in a room to be reused without having to put a larger load on the power source, which normally provides air and water For the paper making process. For the most part, it is a recycling system.Galaxy is Leading Heat Exchanger and High Speed Disperser Manufacturer In India.

Types of Heat Exchangers

Heat Exchanger Manufacturer In India

• Shell & Tube heat exchanger
• plate Heat exchanger
• Regenerative Heat Exchanger
• Adiabatic wheel heat exchangers

Shell & Tube Heat Exchanger:

Tube heat exchanger are made up of several tubes, circulates through the liquid. The tubes are divided into two sets: the first set contains either heated or liquid cooled. The second assembly contains the liquid which is responsible for the initiation of the heat exchange and exhaust heat either from the first set of tubes by absorption of cooling heat and substantially transmits the heating fluid or the phrase by Its own heat pressed against the liquid. In interpreting this type of heat exchanger Caution must be exercised in determining the correct wall thickness and pipe diameter to allow an optimal heat exchange. With regard to the flow envelope and the heat exchanger tube can take one of the three flow path patterns. Galaxy is best Heat Exchanger Manufacturer In India.

Plate Heat Exchanger:

Plate heat exchangers consist of thin plates, which are connected to one another, with a small amount of space between each plate, which is generally held by a small rubber seal. The surface is large and the corners of each rectangular plate have an opening, can flow between the plates through the fluid, wherein heat is extracted from the plates as it flows. Change themselves fluid channels hot and cold liquids, which means that the heat exchanger can actually cool and heat liquid - they are often used in refrigeration applications. Since plate heat exchangers have such a large area, they are often more efficient than the shell-and-tube heat exchanger.

Regenerative Heat Exchanger:

In a heat exchanger with regeneration of the same fluid is directed on both sides of the heat exchanger, which may be either a plate heat exchanger or a tubular heat exchanger. Since the liquid can become very hot, the outgoing liquid is used to heat the incoming fluid, in which a substantially constant temperature is maintained. In a regenerative heat exchanger a large amount of energy is recorded because the process is cyclical, with virtually all of the relative heat of the outgoing fluid to the inflowing fluid being transmitted. To maintain a constant temperature, only low energy must be required to increase the temperature of the total and lower liquid.

Adiabatic Wheel Heat Exchangers:

In Adiabatic Wheel Heat Exchangers, a middle of the road liquid for warm capacity is utilized, which is then exchanged to the inverse side of the exchanger unit. An adiabatic wheel comprises of a huge wheel with wires that go through fluids - swinging to remove warmth or exchange - both hot and frosty.

Furnace Heat Exchanger

Heat exchangers can be found in all kinds of equipment, from refrigerators and smoke stack air conditioners to diesel engines. But when we talk about the heat exchanger in your furnace, we hear some type of technology. Here is a brief explanation of what the heat exchanger does in your furnace.

Heat Exchanger Manufacturer In India

All heat exchangers have the same function - the movement of heat from one fluid (liquid or gas) to another, but depending on the technique of operating in different ways.

The furnace heat exchanger used fuel - propane, natural gas or oil - to generate heat. The air motor of the blower or fan then projected onto the heat exchanger and into the house of the house, which distributes it throughout the house. Pretty simple, right?

To explain a little more, ignite the burner's combustion gases. The gases are sent to the heat exchanger where heat is transferred from the gases to the walls of the heat exchanger.

As the gases cool, the train fan directs in induction evacuation tubes and they are exhausted from the house. This is done at the same time when the hot air absorbs combustion gases before its distribution through the heat of the pipeline from the walls of the heat exchanger.
