Abstract

Using plasma deposition, researchers in China and the U.K. have developed a new technique called dropwise condensation in electric turbine condensers. Compared to filmwise deposition, the new technique is able to enhance the heat transfer coefficients (HTCs) of the condensers. With this technique, steamside HTCs of 30-40 kW/m2K are achievable at condenser pressure levels and steam to cooling water HTCs of 5-6 kW/m2K are obtainable using 0.5 mm wall titanium tubes at moderate water velocities. Dropwise deposition reduces the cost of electric generation by reducing the number of tubes and the pressure levels. When used in coal-fired plants, savings in coal consumption and reduction of CO2 emissions can be achieved.
