Difference between direct contact and indirect contact condenser
Jet condenser
|
Surface condenser
|
Direct contact heat exchanger
|
Indirect contact heat exchanger
|
Simple design. Manufacturing cost and maintenance cost is low
|
Manufacturing cost and maintenance cost is high
|
Mixing of vapour and condensing medium occurred
|
There is no mixing of vapour and condensing medium. They both
separated by wall/surface
|
Condensate may get impure due to mixing. Condensate cannot
recirculate to the system unless it is free from impurities.
|
|
The cooling medium should be pure.
|
Since there is no mixing quality of cooling medium is not important.
|
Condensation is very fast. It requires less amount of condensing
medium to condensate.
|
Condensation process is slow. Require a large amount of condensing
medium to condensate unit amount of vapour.
|
It requires small floor space
|
It requires large floor space
|
It requires condensate extraction pump, the failure of this condensate pump
leads to flooding of condenser.
|
Condensate extraction pump not required.
|
Low vacuum efficiency.
|
High vacuum efficiency.
|
It is less suitable for high capacity plants.
|
It is suitable for high capacity plant.
