Shell and Tube Heat Exchanger.
Shell and Tube Heat Exchanger
Shell and Tube Heat Exchanger are popular in industries because they
occupy less space and offer reasonable temperature drop
The apparatus
consists of fabricated SS shell, inside which copper tubes with baffles
on outer side are fitted. This is two-pass heat exchanger so that hot
water passes to one end of shell through the tubes and returns to
another end through remaining tubes. The cold water is admitted at the
one end of shell, which passes over the hot-water tubes. Valves are
provided to control the flow rates of hot and cold water. Flow rates of
hot and cold water are measured using Rotameters. A magnetic drive pump
is used to circulate the hot water from a re-cycled type water tank,
which is fitted with heaters and Digital Temperature Controller.
Experiments
The main object of the experimental setup is to study the following at various flow rates:
