Why Condensers?

Ideal Rankine cycle

PMM2

Condenser is a device in which steam is condensed to water and rejects latent heat.

Why Condensers?

Needs More Efficiency!

Vacuum Creation!

Classification

I) Surface condensers 1- Air Cooled Condenser

I) Surface condensers 2- Water cooled condensers

I) Surface condensers 3- Evaporative Condenser

II) Jet Condensers 1,2- Parallel vs. Counter Flow Jet Condensers

Jet vs. Surface Condensers:Jet Condensers• Mixing.• Condensate

can not be FW.• less quantity of

CW.• low vacuum

efficiency.• Less suitable

for high capacity plants.

• Simple.

Surface Condensers

• No Mixing.• Condensate can

be FW.• large quantity

of CW.• High vacuum

efficiency.• More suitable

for high capacity plants.

• Complicated.
