So that the water, or other heated fluid, is exitting at the hottest point in the exchanger; where the hottest steam enters the unit.
blocked lines and wear of lines are the most important problems of heat exchangers.
Yes, heat exchangers are used.
The types of heat exchangers commonly used as super-heaters are shell-and-tube heat exchangers and plate heat exchangers. These heat exchangers are designed to efficiently transfer heat from the combustion gases to the steam in power plants, increasing the temperature and improving the efficiency of the system.
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.
Plate heat exchangers use flat plates to transfer heat between two fluids, providing a large surface area for efficient heat transfer in a compact design. Tube heat exchangers utilize tubes to facilitate heat exchange between fluids, offering a more traditional and versatile approach to heat transfer applications. Plate heat exchangers are typically more efficient and cost-effective for certain applications compared to tube heat exchangers.

A contraflow system is where two cars meet at a junction either going left or right
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.
