Question: What Is Heat Exchanger Network?

What is a heat exchanger and how does it work?

Heat exchangers, metal shells and tubes, work by transferring heat from one place to another.

When a furnace burns natural gas or propane fuel, its exhaust/combustion by-products (also known as flue gas) enter and travel through the heat exchanger..

What is heat exchanger channel?

Channels or heads are required for shell-and-tube heat exchangers to contain the tube side fluid and to provide the desired flow path. Many types of channels are available. … Most channels can be removed for access to the tubes. The most commonly used channel type is the bonnet.

What is the point of a 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 fluids may be separated by a solid wall to prevent mixing or they may be in direct contact.

What is difference between condenser and heat exchanger?

A condenser is a device which converts vapour into the liquid state whereas a heat exchanger is a device which is used for heat recovery also to transfer heat from two fluids. Heat exchanger only heat is transferred without phase change and heat is transferred along with the phase change in the condenser.

How do I choose a heat exchanger?

The following criteria can help in selecting the type of heat exchanger best suited for a given process:Application (i.e. sensible vapor or liquid, condensing or boiling)Operating pressures & temperatures (including startup, shutdown, normal & process upset conditions)More items…

What is the difference between a heat exchanger and a radiator?

But a heat exchanger is any device that transfers heat from one fluid to another. Some equipment depend on air-to-liquid heat exchangers. The most familiar example of an air-to liquid heat exchanger is a car radiator. The coolant flowing in the engine picks up heat from the engine block and carries it to the radiator.
