A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. [ 1 ] [ 2 ] [ 3 ] These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure .
The condenser condenses the steam from the exhaust of the turbine into liquid to allow it to be pumped. If the condenser can be made cooler, the pressure of the exhaust steam is reduced and efficiency of the cycle increases. Diagram of a typical water-cooled surface condenser. [10] [11] [14] [15]
Steam leaves the boiler and reaches the condenser after passing through the main valve, regulating valves, nozzles, clearance spaces between nozzles and moving blades, diaphragm and rotating shaft, and other passages. Further, there is a large pressure difference between the inside of a steam turbine and the ambient atmosphere and also from one ...
The steam which was used to turn the turbine is exhausted into the condenser and is condensed as it comes in contact with the tubes full of cool circulating water. The condensed steam, commonly referred to as condensate. is withdrawn from the bottom of the condenser. The adjacent image is a diagram of a typical surface condenser.
When the officer in charge on ship's bridge orders an increased bell, the steam turbine power output is demanded, using more steam and requiring an increased feed rate. This draws more water from the condenser, potentially to the point of going dry and starving the boiler or steam generator resulting in a loss of propulsion. This is until the ...
"In the ordinary way this would have created much noise and clouds of steam, but with the condensing set in action it was all absorbed with the ease with which snow would melt in a furnace! The engine was as silent as an electric locomotive and the only faint noises were due to slight pounding of the rods and a small blow at a piston gland.

The condenser coil of a refrigerator. In systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In doing so, the latent heat is released by the substance and transferred to the surrounding environment. Condensers are used for efficient heat rejection in many ...
