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

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.

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.
