Article history: Heat losses from the thermal power plant cycle are due mainly to heat rejection through the condenser.
Received 14 January 2011 Operating the condenser at optimum circulation water flowrate is essentially important to ensure
Accepted 10 August 2011 maximum efficiency and minimum operating cost of the plant. In this study, computer program codes

were developed in Microsoft Excel macros for simulation of a thermal plant at various circulation water
flowrate, to determine the optimum condenser cooling water flowrate for the process. The study
Keywords: revealed that operating the condenser at reduced cooling water flow rate of 32,000 m3/h instead of the
