The document discusses barometric jet condensers. It describes how barometric jet condensers work by directly mixing cooling water and steam for condensation. Vapors entering the top of the condenser are condensed by water from spray nozzles, while non-condensables are drawn into the tailpiece and discharged through the bottom with the condensing water. Barometric jet condensers are commonly used in various industries to remove vapors where large capacities are required and fluctuations in temperature or steam loads occur.

2. JET CONDENSER
● A type of condenser in which we
condense steam at constant
temperature and pressure
● In jet condenser, we directly
mix cooling water and steam for
condensation.

3. Barometric jet condenser
●Barometric jet condenser is also
called high level jet condenser
●This type has long vertical
discharge which delivers condensate
to the hot well without needing
condensate extraction pump

4. Barometric jet condenser
● The Barometric Condenser is
employed in a variety of industries
as an economical means of removing
air, exhaust steam, and other vapors
from vacuum equipment.
●It has been used for decades in the
food industry for processing edible
oil, milk and other products- for
nearly a century in sugar refining

6. OPERATION
Vapors
entering the
condenser

7. OPERATION
at the top are
condensed by
water from the
spray nozzles.

8. OPERATION
Non-condensables
are drawn into the
tail-piece of the
condenser by the
converging water
stream from the jet
nozzles.

9. OPERATION
Condensing water
and noncondensables are
discharged
through the tail
pipe at the
bottom.

10. APPLICATION
● Condensers are generally employed
where large capacities are required
and where wide fluctuations in water
temperature or steam load occur.

11. APPLICATION
● They are used extensively in
canneries, in sugar, milk, and
other food plants; in pulp and
paper mills, distilleries;
petroleum refineries, and a
wide variety of chemical and
salt manufacturing companies.
