Which type of heat exchanger is preferred for heavy heat loads ?

ANS:C - Series and parallel set of shell and tube

For heavy heat loads, the preferred type of heat exchanger is typically the "series and parallel set of shell and tube" heat exchanger. This type of heat exchanger offers several advantages for handling heavy heat loads:

1. High Heat Transfer Surface Area: Shell and tube heat exchangers can be designed with a large number of tubes and multiple passes, allowing for a significant heat transfer surface area. This increased surface area enables efficient heat transfer even for high heat loads.
2. Robust Construction: Shell and tube heat exchangers are often constructed with sturdy materials such as metal alloys, making them suitable for handling high pressures and temperatures associated with heavy heat loads.
3. Flexibility in Design: Series and parallel configurations of shell and tube heat exchangers offer flexibility in design, allowing for optimization based on specific heat load requirements and space constraints.
