Hi,

 

Can anyone answer that why Surface Condenser is called a "Surface Condenser"...??

In old times British Navy decided to use steam engine boats and replace sail. Steam boats operates on principle of condensing the steams to move the piston by creating a very low pressure in the barometric condenser. In barometric condenser, condensing is done by direct mixing of cooling medium to the steam. The condensing medium in the case of Navy boats will be an abundant seawater. Problem is that this seawater mixes with steam condensate which is not a good idea.  

 

The solution is not to condense the steam by direct contact with cold water, as is done in the barometric condenser. Condense the steam by indirect contact, with the cold surface of the tubes in a shell-and-tube condenser. Thus the term surface condenser.

 

Simply by condensing thru cold surface and not by direct mixing of cold fluid.

Hi,

 

Surface condensers are called as indirect condensers which separates satd vap & cold fluid mixes together. These condensers generally operate at low pressure with sat. temp of vap near to the atmospheric temp. This helps in preventing contamination of condensate with cooling water.
