INTERVIEW QUESTIONS
EQUIPMENT - HEAT EXCHANGER
Test your knowledge on heat exchangers.
1. What is the use of a heat exchanger?
The heat exchanger
transfers heat from one stream of process fluid to another without mixup of
streams.
2. How heat exchangers are classified according to
construction?
According to
construction heat exchangers are classified as Tubular, Plate type, Extended
Surface and Regenerative.
3. How heat exchangers are classified according to
flow arrangement?
According to flow
arrangement heat exchangers are classified as Co-Current flow, Counter-current
flow, cross flow.
4. How heat exchangers are classified according to
heat transfer process?
According to heat
transfer process heat exchangers are classified as Direct Contact Type and
Indirect Contact Type. An example of direct contact type is cooling tower. An
example for Indirect contact type is Shell and Tube heat exchanger.
5. How heat exchangers are classified according to
service?
According to
service, heat exchangers are classified as Heater, Cooler, Condenser, Re-boiler
and Pre-heater
6. What is the function of Baffle?
Baffle is a device
to direct the shell side fluid across the tubes for optimum heat transfer.
7. What is the function of support plate in a shell
and tube heat exchanger?
Support plate is a
device to support the bundle or to reduce unsupported tube span without
consideration for heat transfer.
8. What is tubesheet ligament?
Tubesheet Ligament
is the shortest distance between edge of adjacent tube holes in the tube
pattern.
9. What is welded tube joint in shell and tube heat
exchanger?
Welded Tube Joint
is a tube-to-tubesheet joint where the tube is welded to the tubesheet.
10. What are the functions of tie rods and spacers in
a shell and tube heat exchanger?
Tie rods and spacers,
or other equivalent means of tying the baffle system together, shall be
provided to retain all transverse baffles and tube support plates securely in
position.
