In this work, a step-by-step method was used to study the effectiveness of the steam turbine exhaust condenser. Calculations in this method include a set of parameters in addition to the condensing temperature, vapor temper-ature, inlet and outlet temperatures and pressure distribution. A quasi-two-dimensional model was applied twice on the tube, one on the water side and the other on the vapor side. A computer program in MATLAB was built to evaluate the performance of the condenser. It is applied with different operating conditions of the condenser, such as operating pressure (corresponding saturation temperature of vapor), air percentage mixed with steam, cooling water temperature, and fouling factor on the tube side for the summer and winter seasons. The proposed model was verified for the field operating conditions of the Northern State Company for the Fertilizer Industry (Baiji-Iraq) and showed good agreement with the field data. This technique can be employed to investigate the pressure drop and determine heat transfer properties for all configurations of the condenser (geometrical shape).
