Power plant condensers


Most of thermal power plants or steam power plants use condensers to convert the exhaust steam from a steam turbine to its liquid phase. The improvement of heat transfer between the steam and the coolant in the condenser enables those plants to generate electricity more efficiently and to reduce the amount of the coolant water usage. One of the simple and economical methods to enhance the heat transfer is to modify wetting characteristic of the condenser surfaces. Dropwise condensation obtained by low-energy hydrophobic coating offers 5-10 times higher heat transfer coefficient than the commercial metal condenser surfaces.


MEL develops advanced condenser surfaces coupled with well-designed micro/nanostructures or water-repellent lubricants to control condensation dynamics and to further increase the heat transfer performance at various environmental conditions.
