Condensers are used for condensing of steam exiting the turbine exhaust and extraction of excess heat out of the thermal cycle. Low backpressure in condensers increase the overall efficiency of turbine enthalpy gradient. Condensers consist of tube bundles made of straight tubes, shell, water boxes and neck. Condenser designs are based on thermodynamic calculations, using Doosan Škoda Power’s custom made software and internationally recognized design standards. We are also able to perform steam flow and condensation simulations by using 3D CFD methods.
