In a shell and tube heat exchanger,
baffles are provided on the shell side to ________ .
prevent the stagnation of shellside
fluid
improve heat transfer
provide support for tubes
all options are correct
all options are correct
Baffles are flow-directing or
obstructing vanes or panels used in some industrial process vessels, such as
shell and tube heat exchanger chemical reactors and static mixers.Baffles are
an integral part of the shell and tube heat exchanger design.
The main roles of a baffle in a shell
and tube heat exchanger are :
Hold tubes in position (preventing
sagging) both in production and operation
Prevents the effects of steam starvation,
which is increased with both fluid velocity and length
Direct shell-side flow along tube
field
To increase fluid velocity and
effectiveheattransfer co-efficient of the exchanger.
Hence, the correct option is (D).
