Comparison of Jet condenser (contact type) and Surface condenser (non-contact type)

Jet condenser (contact type) 

• Exhaust steam mixes with cooling water.
• Temperature of the condensate and cooling  water is same while leaving the condenser.
• Condensate cannot be recovered.
• Heat exchanged by direct conduction
• Low initial cost 
• High power required for pumping water.

Jet Condenser

Surface condenser (non-contact type)

• Steam and water do not mix.
• Condensate temperature higher than the cooling water temperature at outlet.
• Condensate recovered is fed back to the boiler.
• Heat transfer through convection.
• High initial cost.
• Condensate is not wasted so pumping power is less.
