Advantages of shell and tube heat exchanger are:
* Its compact design * Capability of withstanding high pressure
Disadvantages:
* It is difficult to readily inspect the shell side of the tubes for scaling or tube damage

Better heat transfer than natural convection. When compared to water or liquid cooled heat exchangers, the argument could be made that air is a cheaper cooling medium.
Heat exchangers are not indentical to furnaces. However, they do serve a similar purpose. Both heat exchangers and furnaces serve important individual purposes. They also aee ulilitzed for different devices.
The purpose of a heat exchanger is that it transfers heat from a liquid to another fluid on the opposite side of a barrier. There are two kinds of heat exchangers parallel-flow and counter-flow.
a plate heat exchanger is a metal plate which is will be in contact with another item eg air or another metal object to move heat from one to another
advantages and disadvantages of plate heat exchangers
Yes, heat exchangers are used.
blocked lines and wear of lines are the most important problems of heat exchangers.
Water tube heat exchanger swimming pool, Coaxial heat exchanger for laser and stainless steel exchangers are some of the heat exchangers used as super-heaters.
the advantages are-keep heat for longerreusablelightweightpopularthe disadvantages are- expensivesometimes made from bad materialscan be harmful to environment
Metal gets oxidized.

heat duty refers to the heat exchangers. heat duty of the heat exchangers is defined as the amount of heat transfered of 1kg of hot fluid to the 1 kg of cold fluid in one hour.
One uses tubes, the other uses hollow, flat conduits.
Fouling factor is essentially used in determining the efficiency of the heat exchangers. Fouling factor is obtained from service (product) on either side of tubes and material of tubes. It basically represents corrosion of heat exchangers tubes which affects efficiency of heat transfer.
