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

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.
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.
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.
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
One uses tubes, the other uses hollow, flat conduits.
advantages and disadvantages of plate heat exchangers
Yes, heat exchangers are used.
There are three main types of heat exchangers on the market today. Type 1, Brazed Heat Exchangers, are a collection of plates, vacuum brazed together with no gaskets. They have a high turbulent flow, which reduces particle build up and the need for maintenance. They are good for water based systems such as radient floor heating and swimming pools. Type 2, Shell and Tube Heat Exchangers, are copper U-tubes in a carbon shell. They are rugged, and are frequently used when the materials being cooled are corrosive. Type 3, Shell and Coil Heat Exchangers, are made of circular layers of corrugated tubing and are installed vertically. They are very efficient and are appropriate where space is at a premium. There are many different types of heat exchangers. The types of heat exchangers are: shell and tube, plate, regenerative, adiabatic wheel, plate fin, fluid, waste, dynamic scraped surface and phase-change.
blocked lines and wear of lines are the most important problems of heat exchangers.
They are pretty similar to a plate heat exchangers. They have large surface areas. It's used for removal of liquid containing in food and in beverages. The real definition is by the css.
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.

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.
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.
